ENTRY LEVEL R-SERIES
Born from Yamaha's racing DNA, the new learner approved YZF-R15M takes race inspiration to the next level thanks to a punchy 155cc VVA engine equipped with traction control, A&S clutch, a quick shifter, smartphone connectivity and stunning new WGP and R1M inspired graphics.
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.
VARIBLE 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.
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.
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.
