Sonoma Valley's premier bike shop offering unparalleled quality, factory certified professional service for bikes ranging from bone stock, to serious performance.

Bad Ass Choppers is the general service, maintanance, repair and customization side of our shop. Whether it's time for a factory service interval, a tire change, an oil & filter change, some new pipes, a tune-up, clutch or transmission repair, carburetor or EFI tuning, or even some custom fabrication to make your bike cool and unique to YOUR liking, that's what Bad Ass Choppers is all about!

Bad Ass V-Twin is the complete engine building, machining & rebuilding side of our shop. Want some better breathing heads and a hotter cam installed to make your bike scream? Is your engine tired and in need of a rebuild or some "waking-up"? Would you like to have your heads ported for making more power? Want a nitrous system installed for some tire shreddin' fun? We can do that!

We may not be the biggest shop around, nor are we the fanciest, but you can bet your ass, we ARE the best!
