Humachine Technologies & Sensual Racing Form Big just got bigger and better. Borrowing its ferocious look and aggression from its elder track sibling R1, the all-new R15 is max powerhouse of 19.3 PS that brings track experience to the streets.
R15 v3 Features
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.
Variable Valves Actuation (VVA)
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.
Assist & Slipper Clutch
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.
6 Speed Transmission
Allows better acceleration even in low gears for a true R experience.
Aerodynamic LED Tail And Headlight
A sharper design that assists in overall airflow with efficient lighting and also includes a hazard lamp and slim twin- eye led headlights.
Gear-Shift Timing Light
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.
Super Wide Tyre
Super wide tire (Front: 100 / 80-17, Rear: 140mm/70 -17) presents the stability of driving 140mm size rear tire aimed at improved rear grip.
YZF-R15 V3.0 gets a sporty, stable handling character from Yamaha’s tradition of crafting a machine emphasizing riding feel. A linked-type Monocross rear suspension is adopted to accommodate the powerful engine character and a wide rear tire are adopted for optimum balance.
