Knowledgeable and super nice folks. They know exactly what they’re doing and they’ll really go the extra mile for you. Great prices too. Definitely has a family business feel. They’ll take care of you. I’m not taking my bike anywhere else

I’ve been a long-time customer of KC Engineering and have always brought my motorcycle wheels here for tire mounting and balancing. I like supporting local businesses, and up until now my experiences here have generally been positive with solid work and professional staff. Recently, I brought in a single 14 x 2.5 wheel just to purchase and install an inner tube. While standing at the counter and watching the invoice being written up, I was honestly shocked to see the total come out to over $80. At that point, I had already brought the wheel in and decided to move forward. In my opinion, that price feels excessive for an inner tube install and balance—especially considering the small wheel size and the fact that the work was completed in under 30 minutes. I fully understand that labor costs in San Francisco aren’t cheap, and I don’t expect bargain pricing, but this felt disproportionately high for the scope of work performed. I’m sharing this as constructive feedback. KC Engineering has been my go-to shop for a long time, and I hope this helps set clearer pricing expectations for future customers.

Brought my bike in to get new tires, walked out with something else broken and the job that they did was bad. My rear tire doesn't feel balanced. Something is off about it. I had to take my bike somewhere else to fix what they claim they didn't touch. I can't even take my bike back to them because I fear they will mess with something else. Riding is about trust in my book, my life is on the line out there. I was desperate and came here cause my usual spots didn't have my tires, it would have been a couple of days wait, I should have waited. Lesson learned. Don't make my mistake. Worst mechanics.

I needed to extract my drain plug bolt, I didn't have a lift to get enough elbow room, called and they got me in and finished right away. Great service, great work, great reputation is well deserved. Thank you K C

Needed new tires in my STR. Called around but CG didn’t install. The other didn’t have anything in stock. Told me to order my own. KC had it all. Good pricing. Cash discount. Replaced a bearing for me and she showed me it was grinding hard. Family owned for over 40 years. Got me in and out in an hour at the end of a busy Saturday. Trustworthiness is important to me and I felt like KC keeps things on the up and up. Highly recommend.
