155cc LC4V SOHC Fuel Injection Engine
The YZF-R15 mounts a new 155cc liquid-cooled SOHC 4-valve fuel-injected engine to achieve excellent power and a high top speed. The engine has a 58.0 — 58.7 mm bore — stroke and a 11.6:1 compression ratio, and produces a maximum 14.2 kW (19.3 PS) of power at 10,000 rpm and a maximum 15 N-m (1.49 kgf-m) of torque at 8,500 rpm.
The new YZF-R15 adopts a new Deltabox frame with superb rigidity balance. With a Deltabox frame, the top and bottom of the head pipe and the pivot points form a triangle, hence the “Deltabox” gives it excellent rigidity balance.
This is the first ever high-performance VVA system that provides torque for ease of use even at low RPM. There are two intake valve cams: one for low- to mid-range rpm and another for high rpm. They switch between each other at the 7,400 rpm mark to ensure good power and torque is present throughout the entire rev range.
An A&S (assist and slipper) clutch is adopted to reduce the weight of the clutch pull and provide low-stress shifting during deceleration. The A&S helps to reduce fatigue for the rider. This also prevents excessive engine braking, thus reducing its effects on chassis behavior. The A&S clutch makes for smooth, enjoyable downshifts.
Allows better acceleration even in low gears for a true R experience.
A sharper design that assists in overall airflow with efficient lighting and also includes a hazard lamp and slim twin- eye led headlights
Ensures optimal performance by telling the rider when to shift gear. R1-styled cockpit equipped with a full-color LCD instrument gauge with shift light and VVA indicator. Also have the connector for USB charging.
