The Yamaha R15S is a sports motorcycle from Yamaha. It has been discontinued. Mechiee still services it at your doorstep. 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 engine that makes 18.1 bhp at 10,000 rpm and 14.2 Nm of torque at 7,500 rpm. Divide power by kerb weight and it has about 129 PS per tonne; by that measure, it is lively, with easy overtakes and relaxed highway speeds. The claimed top speed is 136 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. Its slipper clutch lightens the lever and stops the rear wheel hopping when you downshift hard.
It is built around a deltabox frame. Suspension is by telescopic fork at the front and Linked-type monocross suspension at the rear. Braking is by a disc at the front and a disc at the rear, with dual-channel ABS. ABS on both wheels keeps either tyre from locking under hard braking. It rides on 17-inch alloy wheels with tubeless tyres — 100/80 - 17 at the front and 140/70 - R17 at the rear.
The seat is 815 mm off the ground, which is about average and suits most riders. It weighs 142 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 43 kmpl work out to roughly 473 km per tankful on paper; real-world range is usually lower.
Equipment includes a digital instrument console, an LED headlamp, gear position indicator, windscreen, shift light, low fuel indicator and low oil indicator. Safety equipment includes engine kill switch, side-stand engine cut-off, side-stand warning and malfunction indicator.
The manufacturer's warranty is 30,000 km or 2 years. It comes with 4 free services, the first due at 1000 km or 30 days. For the Yamaha R15S, Mechiee offers a fixed ₹1,199 doorstep service.
It is best suited to riders who want performance and sharp handling.
Recommended tyre pressures are 29 psi front and 33 psi rear, solo or with a pillion.

Its chain drive needs regular cleaning, lubrication and slack adjustment.
