History

The Indian bike market was still primordial as far as high technology motorcycles are concerned when the R-15 was released. R-15 is derived from Yamaha V-Ixion selling in Indonesia, with the engine and chassis remaining the same. The engine was tuned for higher power and torque, 6-speed transmission was incorporated, a linked type sport suspension added on the back. Fairings were added for improved aerodynamics.
