Yamaha YZF-R15


Racecourse Motors Yamaha introduces the entry level R15 now with a bigger 155 cc, liquid-cooled engine that runs a higher compression ratio for increased power. Plus new Variable Valve Actuation for improved low end torque as well as top end grunt. The new chassis is sharper steering and the new bike runs a slipper clutch for smoother gear changes under hard downshifts.

R15 still sips the fuel at a miserly rate but now punches even harder above its light weight.


Single-cylinder 155cc engine

The engine also features a lightweight forged aluminium piston with DiASil coated cylinder wall, larger diameter intake and exhaust ports, upgraded fuelling, a 5.5 litre air cleaner that's 60 percent larger than the outgoing engine, an assist and slipper clutch and a new muffler with a three-stage expansion chamber. In addition to the extra power produced, the new engine is also more economical on fuel, delivering in excess of 450km from a single tank, that's an incredible 45km per litre.

Variable Valve Actuation

Variable Valve Actuation

The cylinder head features two inlet cams: one for low to mid-range rpm and another for high rpm. The switch between the two rocker arms is carried out by a solenoid motor activated at a predetermined rev-range. The result is high revving performance without sacrificing low-to-mid-range torque and rideability. The technology delivers an 18.3 percent increase in power from just a three percent (5cc) increase in engine capacity.

Deltabox Frame

Deltabox Frame

A 20mm increase in width between the left and right pivot points on the updated Deltabox frame, now 221mm, has allowed the fitment of a new delta-shaped swingarm. Reinforcement of the swingarm is by internal ribbing, to accommodate a wider 140/70-17 rear tyre on the wider rear wheel.

Larger brakes

Larger brakes

Braking performance has been increased with a new 15mm larger 282mm front brake disc and twin-piston caliper. At the rear is a 220mm disc with a single-piston caliper.

Race-inspired styling

Race-inspired styling

Slim twin-eye LED headlights have an aggressive glaring eyes look similar to the YZF-R1, while the cockpit features a YZR-M1-inspired triple clamp and multi-function LCD instrument panel.

Aerodynamic bodywork

Aerodynamic bodywork

The racing-inspired bodywork is now more aerodynamic, featuring a central air intake and layered fairings. An indentation in the top of the fuel tank optimises the rider's tuck position. Fuel capacity has been reduced by 1-litre to 11-litres for a more streamlined design.
