Ordered a CB750 caliper rebuild kit. OK, my fault ordered for the wrong year.Sent it back on my dime included the original piston and seal so they could match it up and/or identify the right part number I needed. Followed up right away with an e-mail explaining the situation. Cannot get anyone on the phone. Reply said they do not offer this kind of service instructed me to use their website to identify the right kit. Found the right part and placed the order. Sent another message asking why a company such as theirs could not simply compare my old parts to the new kit. Other suppliers have actually asked me to send old parts for just this reason when in doubt. Reply once again said they do not offer these services and any old parts sent to them are trashed. (their word, not mine) Ridiculous! I repair/restore these older bikes for resale keeping all old parts if new owners want them, show condition and evidence of work I completed. No excuse for this.

The place was small and the people working there was nice but I never heard either way if I got the job or not but it was disappointing..

98% of all my cafe racer parts come from this gem in the peninsula. Very convenient if your in the Bay area.

If you need parts for your classic Honda this is the place to get them. Quality parts and service.

Only dealt with Mike online but will definitely buy again. Top notch customer service. Got me the exact link to the part I needed.Thank you!

Love this store! Have ordered from them a few times now and parts always come just as expected and super fast. They are always shipped out next day and get to me about 3 days later (to Oregon in the US). Will definitely be ordering from them again the next time my old Honda needs something!

I ordered a throttle for my CB350F and had some issues with the cables binding. After talking with the guys at 4 into 1, they quickly sent out replacement cables to fix the issue. Excellent customer service!

I purchased a bike seat from them. Didn’t fit so I sent it back. They kept the seat and refused to give me a refund. Not only do I have no product, I’m out a couple hundred bucks.

A+ on parts and supply. I deal daily with motorcycle parts companies that specialize in classic machines. This crew is absolutely the best! Stay in business! We need you for many years to come! Thank you!

Products are ok quality but good luck returning anything.

I ordered a brake kit and asked if they could customize it to fit my current set up with drag handlebars. I should state that I work at a speed shop so I know exactly what to expect from a reputable company and I am very satisfied. Not only did they ship me a kit to my specs, but they were patient and mannerly the entire time. If Im honest I was easily one of those super annoying and inconveniencing types of customers, and they still gave good customer service. On a side note, I dont plan on being an annoying customer again, and the brake lines are perfect!

Excellent parts selection. Better prices then competitors. Fantastic customer service.These guys are keeping my 1973 Honda CB-450 alive!

Terrible customer service

These folks are great. Want or need parts for your vintage Honda? They have them and even new parts for old bikes. Great people too.

Ordered up some parts to Ottawa Ontario Canada that I needed for a vintage Honda CB500k. Quick and easy and superb quality. Thanks So much! Will be ordering more.

They had the parts I needed at a great price

Love this place. Has everything Ive needed to do a mild restoration of my 73 Honda. Great staff.

Not only do they have a wide selection of parts available on their site, the shipping is always incredibly fast and prompt. If youre restoring an old bike or building a cafe racer (like myself), these guys are one of the first people I go to.

Easily ordered parts online and were shipped quick to my door, I had an issue with the person lacing my wheels with a broken spoke these guys went above and beyond out of their way to help me fix the situation and get my bike done before the show. Look forward to doing business with you again.

Excelent parts, and helpfull customer service.

I dont know that I would do without the place. Best vintage and classic Honda motorcycle parts place literally in the world.

Amazingly fast from the other side of the world, actually got to my door quicker than a part sourced and paid for in the UK 2 days earlier only 90 miles from my home, would use again.

Great service. speedy post to NewZealand

Company made the situation right.

Great customer service 👍
