The Yamaha R15 V4 is a sports motorcycle from Yamaha. It is currently on sale. Sports bikes put performance first, usually with a sportier riding position and sharper handling than everyday bikes. With a 155 cc engine it sits in the 150–250 cc class.
Power comes from a 155 cc single-cylinder liquid-cooled fuel-injected engine that makes 18.4 PS at 10,000 rpm and 14.2 Nm of torque at 7,500 rpm. Divide power by kerb weight and it has about 130 PS per tonne; by that measure, it is lively, with easy overtakes and relaxed highway speeds. The claimed top speed is 140 km/h. It has electric start.
It has a 6-speed manual gearbox with a 1-down, 5-up shift pattern, and a chain carries drive to the rear wheel. It uses a wet multi-plate clutch.
It is built around a deltabox frame. At the front, the suspension is telescopic upside down fork (USD Fork), 37 mm inner tube dia. At the rear, it is linked type monocross suspension. Braking is by a 282 mm disc at the front and a 220 mm disc at the rear, with dual-channel ABS. ABS on both wheels keeps either tyre from locking under hard braking. It rides on alloy wheels with tubeless tyres — 100/80-17 at the front and 140/70R17 at the rear.
The seat is 815 mm off the ground, which is about average and suits most riders. It weighs 141 kg ready to ride. Ground clearance is 170 mm — enough for most speed breakers. It is 1,990 mm long, with 1,325 mm between the axles. Its 11 L fuel tank and claimed mileage of 55.2 kmpl work out to roughly 607 km per tankful on paper; real-world range is usually lower.
