Specifications

The engine for the first and second iteration (v2.0) was a 149.8 cc single cylinder four-stroke engine with four valves and a single overhead camshaft. The bore and stroke were 57.0 mm × 58.7 mm (2.24 in × 2.31 in). This engine had a claimed 12.2 kW (16.4 hp) of power at 8,500 rpm and 14.5 N⋅m (10.7 lbf⋅ft) of torque at 7,500 rpm. 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 a return type six-speed with a constant mesh wet multi-plate clutch.

For the first and second iteration, the bike had a 270 mm (11 in) 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 was a twin telescopic fork and the rear is a linked type single shock suspension. The bike has dual headlights like the other bikes of the YZF-R series.

For the 2017 update, the bike has a new 155.1 cc engine. The bore and stroke are 58.0 mm × 58.7 mm (2.28 in × 2.31 in). This engine also get Variable Valve Actuation (VVA) technology and has a claimed 14.2 kW (19.0 hp) of power at 10,000 rpm and 14.7 N⋅m (10.8 lbf⋅ft) of torque at 8,500 rpm.

v2.0

YZF-R15 v2.0

The YZF-R15 v2.0 had undergone changes as compared to the previous version in the cases of the engine control unit (ECU), drivetrain unit, split-seat design, higher seat height, LED tail light, 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 single shock suspension added on the back.[5]

An unfaired, or streetfighter/naked bike, variation of the YZF-R15 v2.0, called the M-Slaz (also called Xabre in Indonesia; TFX150 in the Philippines and Vietnam)[6], is made in Thailand[7] and Indonesia.

v3.0

YZF-R15 v3.0

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 panelmeter with shift indicator and wider tyres.[4]

A streetfighter variation of the YZF-R15 v3.0, called the MT-15, was launched in Thailand on 6 October 2018[8][9], Indonesia on 18 January 2019[10], Vietnam on 7 March 2019 and India on 15 March 2019.[11] The Indian version of the MT-15 uses a conventional telescopic fork instead of inverted type with the rest of the motorcycle being exactly the same.

The retro-styled naked variation of the YZF-R15 v3.0, called the XSR155, was launched in Thailand on 16 August 2019.[12]
