The Yamaha SDR200 is a 200 cc single-cylinder 2-stroke motorcycle. It was manufactered and sold from around 1986 to 1987. Although it was intended for the Japanese home market only, a few examples have escaped as grey imports.

 

Its distinguishing characteristics are its diminutive size and a chrome trellis frame similar to that of a Ducati Monster.

It's a very rare bike. I looking for one also.

[shaowen101]

ya heard it was a great bike for class 2b. you know where to get one cus my brother once had it when i was really young.

[geekster]

No doubt this bike is a legend. But it may be too powerful for novice 2B riders. Think theres a dude at Simei owning one. Maybe you can 'reserved' the bike in case he decided to sell it off.

[h4hahak1m]

Simei where? Wah i can just drop a note and ask him to call me or something. Haha
