    My go-to for my Honda Helix and one of the few, if not the only, places in the city able to provide…read morea brake/light inspection on my Helix for the DMV. The business is about as old school SF as you could hope for; an honest breath of fresh air. They are fair with their prices, deliver high quality work, and have always been kind and gone out of their way to finish repairs quickly and explain the process involved. Christina (hope I remembered her name correctly) is incredibly organized and communicative. On my last visit, Danny (one of the technicians) really went the extra mile on my behalf. Highly recommend!

    In a pinch, this place was recommended to me. I had high expectations, but soon it soured…read more Overpriced, I felt like I was being scammed. Upon picking up my bike the mechanic was trying to push more services which was odd because what he was pushing had just been done. Then on my trip home my storage box fell off my bike on the freeway, so I went directly back to the shop, they immediately got defensive and tried to blame me or my installer. When I asked for the owner it was deflected claiming he lives out of state. They took no responsibility. I would have at least taken an apology or sorry for putting you and or the public in danger. Lastly, I originally had my two tires replaced, very costly compared to other spots, but testing out the bike, it is shotty work. It doesn't feel balanced and feels shaky and slick. Im gonna have to take it somewhere else to get it looked at cause I definitely dont trust these mechanics. The shop seems okay, this is strictly about the mechanics and the work they've done. Another odd thing that really stuck out to me was how exact the timing was on the finished work, 1 1/2 hours... and I mean exactly. I do not recommend coming to this place, you will end up feeling unsafe, feel like you got ripped off and if something going wrong, it's your fault. I had to go to a different place and spend another 100 to get a new storage box and will be spending more to have someone look over the sloppy work this place has done. They dont care if you get killed out there, there take is, it wasn't them.

    STAY AWAY. DON'T GIVE THEM ANY BUSINESS…read more THEY ARE CREEPS. I was thinking about an old girlfriend, who is having a bad time now with addiction. When she and I lived together, our way around was on my 1970 Triumph Trophy. That bike didn't help anything between us! They nicknamed Lucas Electrics "The Prince of Darkness" for good reasons! We left the Bay Area, and I returned years later alone. I decided to rebuild the top end, and I found a nice cylinder head to replace the one I had. At that time, leaded gas wasn't being sold, and recessed exhaust valve seats were an issue, so I had a nice head to work with. It took them forever to bead blast the head: they didn't get it done when they had said it would be done. I was working more than full time, and using my van to get around, which was in such bad shape that I had to avoid any hills around San Francisco (or get a running start). The shop finally called and said the head was ready- much later than they had promised it. I didn't have any time, within their shop hours, to go pick it up, and I didn't have time for much of anything, unlike when I expected the head to be finished. When I was able to make it over to the shop, they had doubled the cost of the work with "storage fees"! I told them that the job wasn't done when they said it would be done, and that I refuse to pay any extra. Mr. tough guy got all big and puffy and he told me that he wouldn't return my property unless I paid what he wanted, which I refused again, and then he took a swing at me and hit me! They live up to their name: don't give them anything... there are other places to go for what you want, so go to them.
