The Yamaha YZF-R15 is a single cylinder sport bike made by Yamaha Motor Company since 2008.[1] In September 2011, the second iteration, the v2.0, was released in India,[2] and in April 2014 it was released in Indonesia.[3] In January 2017, the third iteration of the bike was launched in Indonesia.[4]

Specifications[edit]

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. The front disc is larger than the previous iteration, with a measured 282 mm (11.1 in). The front suspension is now a inverted twin telescopic fork. This iteration also features assist and slipper clutch.[5]

v2.0[edit]

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 taillight, wider tyres, 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.[6]

2017[edit]

This new version 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.[7]

An unfaired, or streetfighter/naked bike, variation of the YZF-R15, called the M-Slaz (also called Xabre in Indonesia; TFX150 in the Philippines and Vietnam[8]), is made in Thailand.[9]
