Mark is an motorcycle magician! I've been coming to DMC for almost 2 years, found him through Yelp & I wouldn't trust my bikes anywhere else!! Every time I stop by the shop he treats me like a friend. He's getting super busy these days but he always takes the time to explain any problems & describe his work. I'm a new rider but on my second motorcycle. I started with an old Susuki savage that had been sitting for years, he tuned it up, got it running smoothly, & solved my nagging dead battery issues. It took some trouble shooting but apparently the starter / single cylinder 650cc can pretty hard on batteries (despite being on a trickle charger). I needed an upgrade to a super tough battery - Mark was hesitant because the cost was higher but it was really necessary to solve the problem, haven't had an issue since. When I upgraded to a 1989 Yamaha Virago 1100 (with only 6K miles on it!) I took it straight to Mark for a tune up. Obviously this bike has spent most of its life in storage. He flushed the fluids out of all the systems & spent hours getting nearly solid gunk out of her arteries. All the build up was causing the engine to idle & rev at variable RMPs. After a week or so I brought her back in to see why it was difficult to handle at low speeds (in 1st gear keeps wanting to die & required a lot of throttle) I thought I was just a wimpy new rider but Mark make adjustments to the engine to choke it back a bit & worked on the clutch so it was easier for my small hands work the engaging point. His efforts have really improved my ride! It's so much easier to handle & still have tons of power. Thanks Mark!! read more

I've been here 4 or 5 times and every time they've been super helpful. I like to do a lot of my own work and they are more than happy to give me info and recommendations. When I can't do the work myself they have great prices and fast service. They let me know that I had a pretty worn dirt bike tire and offered a used one from one of their race bikes that was in better condition for free. Couldn't ask for better service. You can see the shop from outside and it's very clean and organized with nice equipment. These guys really care about what they do and they do a great job. read more

Asked them to perform a pre-purchase inspection on a motorcycle for me. Amazingly professional, quick, and insane value. Caught something I never would have been able to inspect myself and gave me some extra knowledge before the purchase. Would absolutely recommend them to any of my family or friends who ride in the area. Impeccable communication and service!! read more

I'm so stoked I found DMC performance to service my Suzuki. Thank you so much to Mark for squeezing me in. I'm a huge fan of supporting small local shops that really focus on good customer service & have high quality tech's in the back! Although they didn't do any major repair work this time around, I can assure you they will be handling all future work I can't do on my own. I'd also like to thank Toni for being super friendly, and very detailed with me discussing the charges prior to doing any work. I'll will 100% be calling them in the near future to schedule maintenance. read more

One word, phenomenal! Mark was absolutely outstanding and very knowledgeable. Also very honest. Highly appreciated, I'll be back and would recommend to everyone! Thanks Mark, I'll be back! read more

I went to DMC being super excited to get my motorcycle fixed and looking like a fresh newborn baby. I had high expectations because my motorcycle is my baby and I don't let anyone fix on it. So I trusted this place. They ended up ripping me off and not doing what I asked for. I think the owners name starts with an m? I don't know but if I could give this place 0 stars I would. Please don't go here I don't want you to be ripped off like I was. read more

We purchased our Dyna Streetbob last year and have been taking it to DMC since. The team here has looked out for us and the prices are more than reasonable. We've always called ahead to schedule and they'be been up front with us, if they can get to it right away they do, if they can't they let us know so we are prepared. Seriously, the pricing and the customer service at this location have been fabulous. I'm particular about who I want touching our bike since we "built" her and she was handed to us right out of the crate. I completely trust this team and will continue to do business with them until we leave So Cal. Thanks DMC!! read more

Mark and the DMC team have done great work on my bikes and I've been very happy and satisfied every time I've brought something in. I've had them do everything from custom engine guard installations on a Honda ADV bike to full work-ups on my Ducati Monster as well as tire work. The biggest challenge is that they're a busy shop and that means sometimes a couple of calls to get through and get the bike scheduled. I appreciate that they've discussed options with me if they run into snags along the way and don't push toward just the way they want to do things. Prices and times are very reasonable and appropriate for an indy shop. Will continue to be a repeat customer here. read more

Mark & Brent are awesome! I was given a scooter as a gift, that no one else in San Diego wanted to repair. Not only were they (DMC Performance) doing what needed to be done to it (change the tires) but they went over and above by changing the oil, spark plug and giving it a thorough inspection including nuts and bolt replacement. The attention to detail has made feel safe riding it! I highly recommend these guys for all of your motorcycle needs. I'll be back when I get the new Ninja! Thank you DMC Performance for your fantastic service! read more

Independent mechanic specializing in servicing dirt bikes! Mark is an ex-AMA racer, really knows his bikes, and is one of the nicest and most honest mechanics you'll ever meet. I trust him with my Honda CRF250X, and he's helped clean the carbs and adjust the valves. His prices are outrageously inexpensive and the work is top-notch. My only gripe is that it takes a while to get scheduled and have the work completed.. he really needs another mechanic helping out to speed things along. For the area, no one comes close to the level of service and prices at DMC, but obviously word is out on this place because it's very popular! read more

I highly recommend DMC for any service on your motorcycle! Mark is very knowledgeable, fast, and super customer friendly! I had to fix my bike fast because I needed to sell it, as moving abroad. He went out and beyond to get my old bike serviced, fast, and without overcharging. He even came and picked up the bike with his trailer. I would use DMC again, and again, if it wasn't that i'm moving abroad. read more

DMC Performance - Motorcycle Repair Near Me - El Cajon, California

So imagine this scenario: dead 500 pound bike & 150 pound girl with no real bike riding skills or muscles. Enter a motorcycle shop right near my house and a man named Mark. He saved the day by walking my flat tired, dusty hunk of metal to his shop and brought the beast back to life. Lucky for me (and my laziness) I was recommended to this shop by a friend, and subsequently the glowing reviews on Yelp. The reviews only further highlight Mark's love for motorcycles and excellent service. To be honest, I'm not very familiar with bike repairs so I didn't really know what to expect. I knew I had done a disservice to my bike but I didn't know if it was going to be a $150 endeavor or a $2000 kind of deal. When Mark took my bike and called me to confirm that the battery did indeed need replacing among a few other things, my heart sank when he said, "well I want to warn you, it is kind of expensive." I imagined dollar bills stacking before my eyes and igniting on fire in the few seconds before he continued. I was relieved when he actually gave me the price for the work. The repair was very reasonably priced for the work and time required but not capital "E" expensive where I was going to be eating top ramen for a few weeks. Plus, when I went to pay, he made sure I knew in advance that if I brought cash I'd save a few bucks in card processing fees. I really appreciate this kind of thing since there are plenty of business owners that could care less. I'm likely going to sell the bike unfortunately since it's too grande for this girly, but when I get back around to riding again one day I know where I'd take my bike. Highly recommend this shop if you're looking for a trusty bike mechanic. read more

Mark was very professional and above reproach. I was able to drop my bike off and pick it up the same day and had no issues. Thanks Mark, I will be seeing you again for future service. read more

Junk place , he rips people off left and right . Charged me 500$ to bend metal . He didnt even fix the problem . Needless to say . Just save your money and time snd take your bike to superbike powersports on midway . He is knowledgeable friendly and more than fair . As mark will not return your phone calls if he amswers them in the first place .WARNING WARNING WARNING RIP OFF ARTIST .I WOULDNT LET THIS GUY FIX A BIRD SCOOTER . read more

This is a man dedicated to his work and willing to fulfill what he says he will do to the very end. I have brought my ninja 250r two times now and each time the experience was amazing. I brought in my ninja randomly the first time to do a rear tire change and he happened to have a lift open. did it right then and there no hassle and was out of there within the hour. On top of that they noticed my pads were about done and replaced them at the same time. The second time was for my 6k maintenance. Brought it in Friday evening and he stayed after hours on Saturday till 7 pm to finish it up for me. Now that is dedication that you can't find everywhere. I plan to keep on coming back with all my issues. Thanks Mark, you are awesome!! read more

Came to DMC to see if there was a way to lower my enduro bike a bit so I could get my feat flat on the ground. I spoke to Mark who had some really good ideas and after talking to him decided to give it a go. He fixed a couple other things and switched out the springs and made some other adjustments. It's exactly what I was hoping for and I couldn't be happier. Even the parts he ordered match the bike so it looks great! I'm so happy I brought my bike to DMC! Thanks Mark! read more

Avoid fixing your motorcycle at this place. I have the worst experience ever with them, their mistake costed me more than $3K. They know nothing but treating costumers mean after receiving the money. Also, I asked them over the phone about the prices and once I got there they gave me a higher prices. I HIGHLY NOT RECOMMEND THIS PLACE, You have to be clear with costumers. read more

Mark has been my "go to guy" for anything bike related since I heard about his shop about 6 months ago. His business etiquette and want for return business is unmatched. Recently I ordered some tires for my Fiance's ninja 250 and called up Mark to get them put on. Unfortunately Mark told me for the time frame I was looking for, he would struggle to accomodate. I ended up going to another shop to get them mounted. HOWEVER, Mark called me later in the afternoon and asked if I still needed the job done, when I told him my decision he apologized for not fitting me in and said he'll make it up to me next time I need something. THIS IS PRIME AMERICAN BUSINESS ETHICS RIGHT HERE. When is the last time you had a shop call you and apologize that they were too busy and still try to fit you in? Mark Duncan has FOREVER secured my cycle business repair/maintenance. read more

Mark was professional and offered great service. I compared prices at other motorcycle mechanics and DMC is less expensive. Plus you know you're getting the best service when the owner is working on your bike. I'll be coming back here for another full tune for sure! read more

I started riding a couple of years ago and went to DMC performance when it was still in PB, since it was close by. I moved to Mira Mesa but I still take my bike here, since Mark is exceptionally trustworthy and down to earth. I'm not very mechanically inclined, so it's nice to have confidence that I'm not being scammed. Especially in the realm of motorcycles, where a good mechanic can be the difference between life and death. Anyway my clutch recently took a shit on me, and Mark was not only professional and friendly (like always), he actually took the time to explain his "debugging" process, show me the broken part, and describe his theory on what could have caused it. I don't usually do Yelp reviews but I highly recommend you take your bike to DMC Performance. read more

Mark Duncan, the owner and main mechanic, has been my go to guy for everything motorcycle related for years now. His prices are so low I feel guilty, his work is beyond excellent and professional, and to top it off he is one of the nicest guys I've ever met. He is able to get all the parts, gear, and even accessories I've needed and his prices are much lower than the dealers. And seriously his tire prices installed can't be beat for brand new Michelin Pilots (or any tire I guess.) All in all, try him out once and you'll never need another mechanic for your street or dirt bike. Thanks Mark!!!! read more

DMC Performance - Great Job! - Motorcycle Repair Near Me - El Cajon, California

I have a 1993 KX80 I've owned since I was a kid. It was mothballed in storage for almost 18 years and my buddies and I wanted to start messing around with pocket bikes. I called a few places to get it road ready and I settled on DMC because the owner Mark actually seemed like he cared. Other places said they didn't mess around with small bikes. He was quick to get it going and charged me a fair price. Great personal service, he's earned my business for life, thanks to Mark and his whole team! read more

Mark is honest if you're honest. He treats rider safety as priority. My experience with Mark always gives me confidence as a rider. He regularly works on my '12 Monster 696. If you're not familiar, working on Ducati is more of a pain compared to other bikes. Mark's turnaround is usually same day for simple things like oil change, brake flush, etc. Overhauls take more time since I see him with, at most, one other person. Sometimes he's a one man crew. If you expect super fast turnarounds or a similar experience with a factory service crew, look elsewhere but if you want attention to detail and have some patience, Mark is your guy. He's transparent with his labor hours, parts, and gives discounts on tires.. if you're nice :) read more

Asked how much to adjust valves. He said $140! Brought bike with a spark plug and plastic off. Charged me $180. Asked him about plug condition he said it needed replacing. He didnt show me old plug. Said valves were a little tight. Bikes harder to start now. I question whether he even did anything. Not going back he seems shady just telling it like i see it. read more

Beyond expectations. I've taken three bikes here for all different reasons, and each time was a great experience. Mark knows what he's doing, takes pride in what he does and provides exceptional service. I feel lucky to have him in the neighborhood. read more

I had some bad experiences with other motorcycle shops around San Diego, until I found DMC Performance. Mark is super helpful and charges extremely reasonable rates for service. Better quality service for a fraction of the cost! Check this shop out! read more

The owner Mark goes above and beyond to not only fix your bike to the highest standards, but is also super nice and accommodating. Honest and someone you can clearly trust with your bike and money as many already do. Wouldn't charge me to fix my second broken valve stem and it was a quick and reliable job as usual. Feel lucky to have a business like this so close by! A good lawyer and a good mechanic my friends. Queue the King Stalman's jingle.. read more

This review is LONG overdue, better late than never. Mark has worked on my vespa a few times over the years. He has always been so professional, kind and honest. He is one of the hardest working people I've met in San Diego and is always eager to help with any questions or concerns. He is so patient and explains things very well. I got new tires here, battery changed and most recently my gas pipe thing broke and he fixed it immediately. With so many dishonest mechanics out there it's a breath of fresh air to come across a place like this. Thank Mark! read more

My bike got ran over in a parking lot and suffered various cosmetic damages as well as a few mechanical issues. I dealt first hand with, Mark, who was very straight to the point and helpful. I like this location because it is close to my house and easy to walk to enterprise if your bike is your main source of transportation. Overall, my bike looked brand new when I arrived to pick it up, they washed and waxed it as well. The mechanical issues have all been taken care of, all of this in a timely manner. I recommend this place if you're looking for: 1. Straight shooters 2. Efficient service 3. And quality work read more

If I had to guess, Mark has bailed me out of at least 5 sticky situations. I own a ATV and motorcycle rental business based in Pacific Beach and Glamis. Mark has fixed everything from frame damage to countless clutches. I've been through 5 mechanics and Mark is definitely the best. He's a good guy and he is dependable. What else can you ask for? Mark, has gone way out of his way to make sure that I always had my fleet in tip top shape. The only thing Mark needs to do is charge more for his services. read more

Best bike mechanic I know. I'm a automotive technicial myself but work a lot, and not on bikes, so I looked for a place to go take my 93 CBR900. I would not go anywhere else. He does great work, very knowledgeable, a nice guy and he has THE best prices. It's so cheap and honest work I try to "pay extra" whenever I can. Take your bike here and you'll know. read more

Called DMC based on location, and spoke with Mark. Yes, he could get my YZ250F in that day for some misc maintenance and repairs. Cool! Dropped the bike off, and Race greeted me as Mark was working on a bike. We ran through the list - no problem - they could do it. About a week, we thought. Race called me a couple of times to keep me informed and to ask me to make some decisions on upgraded parts. Bike was ready in 6 days, all parts installed, running well, no surprises, all at a reasonable price. The guys are friendly and responsive. I'll be taking my other toys there as well. HIGHLY recommend! read more

Mark was outstanding. I went in with an unknown electrical issue on a fully custom VRod muscle. I was concerned as to what the time frame for repair could be and then the labor costs while trying to figure what the issue was. All things considering, when he was done compared to the 2 weeks he had my bike, the price certainly did not reflect it. He figured out the issue and it cost me only a fraction what I thought it was going to cost. Very friendly and made sure to share the details of the problem when I picked it up. It also looked to have been cleaned up more than when I dropped it off. I will definitely be going back there for future services. Thanks for the help Mark. read more

This review serves as an update to my previous post... Today Mark and I spoke face-to-face and worked out the differences I wrote about previously as two civilized human beings. What I learned today about Mark is that he is very passionate about his work and cares deeply about the safety of his customers... which is very comforting to know when you are taking a corner at 50mph after having work done (or a tire changed) on your bike. I didn't get the name of the employee who helped me today, but he was super helpful and answered all of my questions without any hint of attitude. It's heartening to know that two adults can hash out their differences and emerge from the situation in a mutually beneficial position. I highly recommend the group at DMC for all of your motorcycle needs... plus, they're expanding (upstairs), so no more pacing in the Chase parking lot waiting for your motorcycle to be finished. I gave 4 stars now, but one or two more experiences like today and DMC will be 5 stars. read more

I'm lucky enough to live right down the street from Mark and his shop. You can tell Mark has a passion for motorcycles and for helping people. His pricing is probably the best there is in San Diego. I've taken my bike to many places in the past but they do not compare to the quality service and the competitively priced services Mark provides. Recently I had a flat tire from a framing nail I picked up on the ride home. Mark was able to get my motorcycle in and have the tire changed on extremely short notice. I appreciate his time and am thankful that he was able to squeeze me in. Do yourself a favor and bring your motorcycle to Mark for your next service. You will not be disappointed. read more

Mark is awesome! I prefer to work on my own bike and am an automotive master technician, but when I lack the time or the job is more complicated than I care for, I go see Mark. He knows what he is doing and I have no problems leaving my bike with him to work his magic. His prices are simply the best and his quality is even better. If you are looking for an honest, competent mechanic then look no further, you have found him. I took my sv650 to him to fix a massive oil leak, he finished the job very quickly and now it runs even better than when I dropped it off! Thanks brotha!! read more

Brought the bike in when the engine was making grinding noises and the battery had failed. They started up the bike and said the engine had siezed when I wasn't there instead of opening it up. Said it would be $3000-$4000 for a rebuild. Instead I got a used motor to replace in there. They gave a poor explanation of what caused then engine to sieze. They then had to do a valve adjustment due to poor compression, which had to be redone by another mechanic. On top of that that the oil was very dirty even after they did a supposed oil change and cleaned the replacement motor. They had terrible customer service and wouldn't pick up when called. Whenever calling me, they would leave a message saying to call back with no details, but then wouldn't pick up when I called back. On the final receipt they did not itemize anything except for the oil and service. Everything else was listed as "custom amount" Edit: Owner called to apologise, which was nice... However, there were still issues that need to be addressed with their customer service. I get a detailed report of each item checked and worked on, as well as diagrams and measurements on valve clearances from other mechanics. Things need to be clearly itemized especially when the bill is close to $1000. read more

Mark with DMC Performance is as good as it gets! I made my account specifically to write this review, I was having a lot of trouble with my WR450 and Mark quickly solved the problem and got me back out out riding! His costs are very fair and less than the other shops in the area, I will definitely be returning for all of my future needs, thanks Mark! read more

DMC Performance - Some Supermotos out front of DMC - Motorcycle Repair Near Me - El Cajon, California

Best place to get the basic maintenance done without dealing with dealers at decent price. Ordered a chain for my monster. Mark called me when the chain was in the shop and replaced it in minutes. He offered free adjustments when needed. Definitely this is the place to go especially if you don't have garage and don't want to pay arm and a leg for oil change. pads, chain etc. Thank you Mark read more
