This bike's engine might displace only 150 cc, but with genes from the likes of the legendary Yamaha R1 and R6, this motorcycle has been one firmly cast into the history of motorcycling arena in many developing countries. It's light, easy to flick, and great at a race track, just like its bigger siblings- the Yamaha R1 and the Yamaha R6. This cheap yet very satisfying ride has fulfilled the dreams of many who thought liter class and super sport machines were something they could never possibly own. It competes with the Honda CBR250R, the Bajaj Pulsar 200NS, the Royal Enfield Bullet(price-wise) and the KTM Duke 200.
The first generation YZF-R15:-
Now in its second generation, it still continues to be a successful bike for Yamaha. It may produce just about 17 ps of power, but all that power has to push around a weight of only 136 kg, so its quite fast. The engine too is very sturdy and strong, allowing for a high level of modifications, leading to the production of more power and hence, resulting in a better power-to-weight ratio.
The 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, six-speed transmission was incorporated, a linked type sport suspension added on the back. Fairings were added for improved aerodynamics.
The engine is a 149.8 cc single cylinder four-stroke engine with four valves and a single overhead cam. The bore and stroke of the engine are 57.0 × 58.7 mm (2.24 × 2.31 in). The radiator is placed in the front of the engine with a fan behind it. The coolant reserve is on the left side up and behind the radiator.
The transmission is return type six-speed with a constant mesh wet multiplate clutch.
The bike has a 270 mm single disc with dual piston calipers in the front and a 220 mm single disc single piston caliper at the rear, both the brake systems being made by Nissin of Japan. The front suspension is twin telescopic fork and the rear is the advanced linked type monocross suspension.
The bike features a dual headlight like other bikes of the R-series. The front tire of original R15 is 80/90-17 and rear tire is 100/80-17 while version 2.0 features radial tyres of size 90/80-17 for front and 130/70-R17 for rear.
