Why Drive Chain and Transmission Are Important?

The motorcycle drivetrain and transmission are often the most neglected items on a motorcycle. Builders will spend countless hours developing a high horsepower motorcycle engine without giving a second thought to the drivetrain or the transmission. Now we love those high-powered engines just like the next guy, but all that energy goes to waste if you cannot get power to the ground.

Choosing The Right Drive Chain

At Lowbrow Customs we have the parts you need to do just that. It doesn’t matter if you are working on a Harley Davidson®, a Vintage Triumph®, or a XS650 Yamaha motorcycle, we have something in our product line for you.

For our customers with a full chain drive we have our exclusive Lowbrow Customs 530 motorcycle drive chains that deliver excellent performance and quality at a really reasonable price.

For the customers that wish they had a chain drive, we also carry a nice selection of complete belt to chain conversion kits. These kits come complete and help you get the job done right the first time without all of the guesswork and headaches. If your clutches need some love you are in the right place! We carry a nice selection of replacement clutch plates, springs and hubs to keep everything operating at optimum levels.

We Carry Full Specs of Gaskets and Transmissions Hardware

At Lowbrow Customs we also have a full line of simple replacement parts like gaskets and transmission hardware as well as specialty items like transmission bearings and bushings.
