The entry level R15 now comes 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.
The newly designed midship muffler adds cadence to overall styling. It adopts a carbon-look pattern on the surface as well as a model nameplate to add to the high-performance image and the feeling of quality. The design of the end cap is also new.
Fuel injected four-valve 150cc liquid cooled engine runs a forged piston and aluminium cylinder like its ‘R’ series brothers
Just like the YZF-R15's bigger brothers, there is a high-mounted radiator located between the R-Series inspired fairings for efficient cooling performance.
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.
A separate-section seat enables a better feeling of seat grip in sporty riding. This new seat design features a slip-resistant seat cover material, excellent cushion qualities, optimised shape for the inner thigh contact area and the cushioned front edge
YZF-R15 sports image is carried through to the cockpit where R-style analogue tacho, digital speedo, trip and fuel gauge inform the rider
YZF-R15 version 2.0 is equipped with a linked type monocross suspension that delivers a comfortable ride and a cushioning performance that is less prone to bottoming out.
A larger 220mm diameter rear disc brake has been adopted to achieve a better balance with the new rear 130mm rear tyre size and ensure good braking power and operability. This larger disc is coupled with the piston-slide type single-pot caliper.
The long swing arm design is a feature fed back from Yamaha's YZR-M1 MotoGP race machine and it is effective for ensuring outstanding rear tyre traction. It's cast in one piece by the gravity casting technique that enables a quality cast with great freedo
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.
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.
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.
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.
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.
