2003 Suzuki JR50Edit

 

The 2003 MY JR50 is an entry-point dirt bike which is a great educational platform for the first-time riders. Built with a bulletproof steel frame and rolling with equally resilient wire-spoked rims, the JR50 can take a lot of abuse and still run smooth.

The JR50 arrives with a chain final drive and a single-speed, automatic clutch transmission for easy operation. Riders will be able to focus more on steering, balance and tackling obstacles and will quickly build up confidence aboard the JR50.


2006 Suzuki JR50Edit

   

Hey, kids wanna have fun, too, you know? If their parents are riding, why shouldn't they ride, too? Here's a nifty off-road mini bike which will not only put a big smile on the youngsters' faces, but will also allow them to start honing in their early skills and even surpass their teachers.

You're betting on a 49cc two-stroke machine with a throttle limiter, a single-speed auto-clutch transmission and sporting a livery inspired by the RM competition bikes. Tough as nails and light, the 2006 MY JR50 will be easy to pick from the dirt and still ride on like the wind.
