Yamaha YZF R15 V4

Under its wind-tunnel sculpted aerodynamic fairing sits Yamaha's refined 155cc single-cylinder, liquid-cooled, SOHC 4-valve engine with Variable Valve Actuation (VVA). Tuned for OBD-2 and E20 fuel compliance, the motor generates 18.4 PS of maximum power at 10,000 rpm and 14.2 Nm of peak torque at 7,500 rpm. The dual-cam VVA system seamlessly shifts intake profiles at 7,400 rpm, delivering smooth, predictable pull in traffic before unleashing an electrifying top-end charge toward its 11,000 rpm ceiling. Power is delivered through a 6-speed gearbox equipped with an Assist & Slipper clutch and an electronic Quickshifter that permits lightning-fast clutchless upshifts on track and open highways.

Chassis engineering has taken a monumental step forward with the inclusion of 37mm inverted front forks, which dramatically enhance front-end torsional rigidity, brake-dive stability, and tyre-contact feedback under aggressive trail-braking. The rear features a link-type Monocross shock absorber mounted to a high-rigidity die-cast aluminium swingarm, connected to Yamaha's stiff Deltabox chassis. Electronic rider safety is elevated to premier standards with a standard Traction Control System (TCS) that monitors wheel-speed sensors and instantly cuts ignition when rear wheel slip is detected on damp or gravel-strewn surfaces.

Ergonomics remain authentically supersport with low-set clip-on handlebars and rearward-biased footpegs, creating a race-canted stance that tucks seamlessly behind the M-duct fairing screen to minimize aerodynamic drag at triple-digit speeds. The redesigned digital LCD instrument cluster features dual display layouts (Street and Track modes), lap timers, gear shift indicators, and Bluetooth smartphone pairing via Yamaha's Y-Connect application for call alerts, fuel tracking, and maintenance logs. Supported by a wide 140/70-R17 radial rear tyre, the R15 V4 yields exceptional grip while returning an impressive 45 to 50 km/l real-world fuel economy from its 11-litre fuel tank.
