Yamaha R15S Yamaha’s racing DNA now comes with the comfort of the Unibody Seat. The manifestation of legends like M1 and R1, the R15S is installed with the Unibody Seat that offers comfort and ease not just to the rider but the pillion too.
Racing Instinct – Passing on the “R series” DNA
Yamaha R15S Multi-function LCD Instrument Cluster with Gear Shift Indicator
Contrary to the earlier dual level seating, the Unibody Seat is created with a singular, flowing seat design that offers comfort to both the rider as well as the pillion. The broader, angular seat is smoother and offers a better riding experience true to Yamaha’s racing legacy.
The new R15S adopts a 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.
The aluminum swingarm give you the advantage of significant reduction in unsprung weight which makes the bike easier to handle.
Yamaha R15S 155cc LC4V SOHC FI Engine
This liquid cooled single overhead camshaft fuel injection engine churns out 18.6PS@10000rpm and 14.1Nm@8500rpm. Features an advanced die cast aluminum (DiASil) cylinder with outstanding cooling performance.
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.
Yamaha R15S 6 Speed Transmission
Now shift gears without worrying about economy. The new R15S with 6-speed transmission allows to cruise at low RPM even in higher gears, thus saving fuel without missing on the thrill.
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.
Dual Channel ABS
Enjoy great performance now with superior control. R15S comes with 282mm front and 220mm rear disc brakes with Anti-lock Braking System (ABS) which means precise braking even when the bike is speeding up, without any wheel lock-ups. This ensures a confident inspiring ride and let the rider enjoy the ride to the fullest.
140mm Super Wide Radial Rear Tyre
140/70R17M/C 66H radial tyre has been adopted at the rear with flexible side walls for better grip while cornering and superior shock absorbing capacity to ensure a more comfortable ride.
Side Stand Engine Cut-Off Switch
With the in-built side stand engine cut-off switch, you do not forget to remove the side stand during those immediate rides.
