or a 1981 Honda and when it came it was the wrong part they were not helpful in replaceing it with the right part as I requested. all they cared about was me changing my bnegitive reiew that I gave them. They did refund me my money back however I had to reorder the part over agin and then they stopped accepting my offers for buying the part over again. Now I ask how can this be the rith thing to do when they are the ones that sent me the wonrg part in the first place, it was totaly their mistake. This is not the right way to do business no matter what their size is. I requested that all I wanted was the right part that I rdered and paid for. Now I ask is that so wrong? Plus then they stopped me from making the purchase overagain fo make their mistake right. read more

BUYER BEWARE!!! Worst customer ever!!! Ordered parts over 2 weeks ago. said 2 to 4 days. Offered to buy part again, as I needed for a children's cancer fundraiser. They said it's not their problem. Will never do business with them again! No time for a company that doesn't give a darn about their customers Jim G. Fresno California read more

4into1 - Email from 4into1 employee. - Auto Parts & Supplies Near Me - Hayward, California

bought an Charlies Place ignition from them, it was defective and I was told they don't accept electrical items for returns. now I'm stuck with a 300 dollar piece of junk. read more

Genuine & aftermarket part purchase for vintage motorcycle is extremely limited in Canada. 4into1 had great selection of vintage motorcycle parts at a reasonable price. Delivery of parts was quick. Extra tax required on parts to be paid as due to import fees. Parts placed onto vintage motorcycle and very happy with results obtained. ** Front Brake Caliper Rebuild with 4Into1 Parts** Motorcycle- 1982 Honda GL 500 Silverwing Interstate read more

Complete idiots. I gave them delivery instructions not to ship FedEx as they don't deliver where I live. They sent it FedEx. And they won't communicate with me. If you have any other way to order don't deal with them. They have wasted my time as wll as my money. read more

Never had problem with 4into1 now. I ordered 6 items from them . I received 5 items. I paid through PayPal . Got my order promptly. I email them about the missing item , gave them the order number as well. No response!!! Waited a week and sent another email, no response !!! Called their phone number, that's a joke, they don't do business by phone calls. The message said to email them, another joke . So I have now sent 4 emails asking them to send the item I payed for through PayPal. Sounds pretty easy right? So now I'm contacting PayPal'S problem hot line. Not A Happy Customer read more

Ordered two mirrors for motorcycle, they sent two for same side. Can't call or send back. Can't get no one to help.

Bought a Sena Outrush R from them through Amazon. This helmet arrived defective, it would pair with any phone I tried to connect to it but would not function. I reset the Bluetooth and tried everything I could find about the system online and finally decided I just wanted the item replaces as the fit and finish were great and my other helmet in the same order from Sena was FANTASTIC (Sena Impulse for me and this one was a Outrush R for my wife). I filled out the return with Amazon and requested a replacement as this was the helmet we wanted. That went through fine, then I printed the label and dropped it off at the UPS Pickup place locally. An hour later the company canceled my replacement order and said Tough luck, they don't do replacements so I would have to contact Sena for warranty work. I contacted them and asked why it was canceled as soon as I saw it was and they replied with the above information and said that I had to contact Sena. I responded to them AGAIN telling them I couldn't because the helmet was already shipping to them and again they said we don't do replacements contact Sena. I explained a third time that the helmet was on its way to them already and this time radio silence so I contacted Amazon support. They said that the helmet could be refunded under the A-Z program but I had to wait 48 hours for the company to respond once they contacted them on my behalf which they did, giving the company the same info I had and the company replied to me that I had to contact Sena. I called back into Amazon and was told I still had to wait 48 business hours before they could process the A-Z claim even though the company had responded and brushed me off again. Disappointed all the way around. I eventually just Ordered an upgraded Impulse helmet for my wife as well at double the cost and am sure she will love it but she did not need the mesh and some of the other features that drive the price way up. If you are thinking about buying one of these just make sure you do not buy it from... Amazon seller 4into1 (4into1.com) read more

Placed several orders over last 3 months for '78 CB750FourK. All worked great. Fast shipping. 1 return was easy. read more

They specialize in vintage Honda parts, some OEM, mostly remanufactured. If they don't have it, good luck finding it. Prices are fair, shipping is fast. I have yet to experience poor quality or service. Fantastic interactions all around. read more

Great pricing, easy to use website, quality products, and great customer service. Bought quite a few products for my 1972 cb500 four and wouldn't choose another site. Thank you all! read more

Parts are not OEM quality and do not fit. I bought a carb rebuild kit for 1969 Honda Z50A and the bowl gasket was to larger and caused gas to leak everywhere. I contacted them for refund, they asked for proof that I had an original carb to be sure I had the right parts. I provided pictures and all information they asked for and they still were saying they could not verify my carb was original. I am the original owner of the bike and know for a fact it is all original. They refused refund, I will be contacting Amazon for deceptive business practices and if Amazon does nothing I will contact my bank. I am tired of companies getting away with ripping off the customer and then the marketplace they sell on will not help either. Ty Nguyen was of zero help and when I asked for proof on his part that is when he told me they would not help me. read more

UPDATE: You won't find a phone number on their site. Ask them to call you and "Sorry, we don't offer phone services...." is literally the response. Original post: Unfortunately, they seem to have parts I need. However, the parts are not what is promised. First, pictures don't match what is shipped and the customer pays shipping both ways, no exceptions. Pictures when dealing with vintage parts is important because parts can be difficult to identify properly. Second, some parts require machining before they actually work. I had to tap the mounting threads in the headlight to get a bolt to go in. Seems like that should have been a bolt on application. Third, their motorcycle control lever "set" is NOT a set. They do not match. Completely different mounting mechanisms and bolts patterns. Fourth, and worse is the master cylinder had so much manufacturing debris it clogged the return port and left me stranded with brakes that wouldn't release. Did I mention they do not back their products and charge the customer shipping both ways, no exceptions. I'll be moving on to other vendors. If you decide to use them, just remember if there are issues with their parts or their representation, you still get to pay return shipping, no exceptions. 4into1, feel free to reach out if you want to make it right, but everything stated here is based on fact so I won't be changing it. UPDATE: You won't find a phone number on their site. Ask them to call you and "Sorry, we don't offer phone services....". read more

I purchased a helmet through Amazon. Wore the helmet once and realized a defect, the piece to slide open the air vent was missing. Once returned to 4into1 they are charging me a restocking fee. They are only refunding me 39% of the amount I paid. I will never buy from them again. read more

Parts arrived promptly, well packaged, detailed packing slip and appear to be of excellent quality. TY very helpful with amending order. Highly recommended. read more

They misrepresented the part, and then refused to accept return, and were hostile about it too, worst motorcycle parts Bp vendor around, zero service or knowledge either read more

I have ordered a number of hard-to-find vintage parts from them. Their turn-around times are quick and they've had quite a few of the parts that wear out on an old 73 Honda. I've used their online store three times now and I'm very satisfied. read more

This doesn't get much better. Great selection of parts for all the Honda CB's. A great mix of genuine honda parts and aftermarket parts in good quality. 4into1 has a great and very specific description of all the parts for sale. This means that there never is any doubt about the fit for your specific model. Shipping prices are very low and shipping time is very fast! Too good to be true? No, that's just how they do it. From CA, USA to Denmark in Europe took approx. 2-4 days! Even when my postal company made a mistake, 4into where quick to handle it without any losses for me. Very friendly and great communication. Can highly recommend to check out their page if you are looking for Honda spares and motorcycle accessories. read more

I ordered a foot peg for a ct90 from them. The peg looks that same but the internal diameter is a lot smaller. Not a happy customer.

4into1 has been a huge help in getting my 1981 cm400c going. My bike is somewhat of an oddball but they still have had plenty of parts for it. I live in mountain view but my girlfriend lives in the city so I have requested local pickup after purchasing online. I have gotten clutch springs, a petcock and new mufflers for my bike. All parts have worked great and the customer service is top notch. I will be buying more stuff from them soon. read more

Ordered parts 2nd day air yesterday because I need the parts by tomorrow. Card was charged but order still has not shipped.

The stock is amazing and the customer support is great too. I've bought stuff from overseas and received it quickly in under 15 days :)

My 4into1 order was farmed out to other vendors from both Callifornia out of state and not shipped from the "shop." You can save money and shipping delays if you search the internet for your motorcycle parts like they do. If the order is wrong they drag their feet getting back to you about returns. I will not trade with them again. read more

Great selection of genuine Honda and after-market parts for my CB550, very helpful staff and reasonable prices. So glad to have this place in the Bay Area. read more

I bought a fuel valve to replace the little white plastic hose pinch clamp originally supplied with the Air Power America 5060TS Topsider. It's a perfect replacement, no leak, works out successfully and I am super happy about this product plus the excellent customers' services provided by Ty N., great store! read more

Restoring a 71' CB350 and needed all new cables, was able to find the parts very quickly and browse the different options as well. Shipping is very reasonable and extremely fast (not only the actual shipping time, but the handling time as well). Had to make an adjustment to my order, and after an email received a very quick and friendly email with what they've done and what I needed to do in order to make the changes. Couldn't ask for a better place to get these parts, would certainly refer anyone to come here first stop! read more

As a 75 CB750 owner, I spent a ton of time on dimecitycycles, ebay, and amazon trying to find parts specific my bike. Most of the time, these are parts I need immediately since my bike would be out of commission and waiting an 2-3 days is not acceptable. Well, 4into1 is such an asset for us CB owners in the city and never again will I scour the internet in search of parts or wait 2-5 days until the part arrives. I can just drive over to their store and get what I need. I've already picked up my Biltwell Gringo helmet, in-line fuel filters, fuel lines, spark wires, spark caps, air filter, and oil filter from them for an incredibly reasonable price. It's a one stop shop for all the vintage bike owners there. The staff there is extremely friendly and helpful. read more

Been ordering parts from them for my 77 cb750 ever since I found out about this place. Has everything I need and more for my rebuild. Great customer service, fast shipping and very reasonable prices. If your ever in need of parts for an older Honda, this is the place to start! read more

sold me a petcock that leaked fuel onto a hot engine, and was aware of it before i emailed them from previous buyers, yet continued to sell the part. Also refused to take back a electronic piece that was broken when I received it. Horrible customer service, and cheep parts. Do yourself a favor and get your parts from vintagecb750, or dimecitycycles. read more

Fast shipping and quality parts but don't make a mistake on your order. I was told it was my fault that I received the wrong part ( and it was ) and they refused to switch it out. I have purchased 100's of parts from 4 into 1 and made one mistake. read more

Good shop. I've dealt with them online a few times. Shipping has always been prompt. Website is stacked with goodies. I'll keep checking their site as long as my 550 needs some extra lovin' read more

Good source for your needs for older Honda motorcycle. As a CB500 owner, I've found the parts I've been able to get through their brick and mortar as well as on their web page. This has saved me a lot of time looking around. The customer service is great, the prices are hard to beat, the shipping is always prompt, and I've been able to find just about everything I need for my CB500. I don't think you can go wrong. Give them a try! You won't be disappointed. read more

Amazing customer service. I ordered a shield from them (for the Gringo S, love this helmet) and it came damaged from shipping. They replaced it hassle free! Would def purchase from them in the future. Thanks! read more

My go to place for my cb750 restoration. Staff is always friendly and knowledgable. Huge inventory of parts and accessories and can't beat the price read more

A priceless resource for those of us that repair and restore vintage Honda motorcycles. They carry a really large selection of reproduction and OEM parts, at competitive prices, and always ship quickly and reasonably. On a few occasions where I have had to return items service was prompt and professional. Excellent vendor, they set the bar pretty high for the rest of us. read more

Great shop. Rufus and Marty are great to work with, ship quickly, have a great selection, and are very knowledgable about these old bikes.
