[1] The YZF-R15 v2.0 had undergone changes as compared to the previous version in the cases of the engine control unit (ECU), swingarm, drivetrain unit, split-seat design, higher seat height, LED taillight, wider tires, larger gear ratio (15/47), longer wheelbase, rear mudguard, and redesigned middle and tail section.

The engine performance was largely similar, still having a six-speed transmission and a linked type of single shock suspension added on the back.

The R15 Version 2.0 uses Yamaha's VVA (Variable Valve Actuation) technology, which improves engine performance and efficiency across a wide RPM range.

Performance: The R15 V2.0 is known for its excellent handling and cornering capabilities, owing to its lightweight chassis and low center of gravity.

Suspension: The front features telescopic forks, and the rear uses a monoshock unit, providing a balance between comfort and performance.

Technology: The R15 V2.0 features an analog-digital instrument cluster, which provides information such as speed, fuel gauge, trip meter, tachometer, and gear position indicator.

The updated engine performance, with the introduction of VVA, was aimed at providing a more linear power delivery, making it smoother to ride.

Target Audience: The Yamaha R15 Version 2.0 was designed primarily for enthusiasts who were looking for a high-performance 150cc motorcycle with sports styling.

The v3.0 has undergone changes as compared to the previous version in the cases of the updated bodywork and engine, now features VVA technology, assist and slipper clutch, hazard lamp, inverted front suspension fork, all-LED lighting system, full LCD planimeter with shift indicator and wider tyros.

The Yamaha R15 V4 sits on the Deltabox frame, a design that is based on technologies garnered from the YZR500 GP competition machines.
