New Yamaha YZF-R15 V4, YZF-R15M motorcycles, Aerox 155 maxi sports scooter launched

NEW MOTORCYCLES: The R15 V4 comes in 3 colours racing blue, dark knight, and metallic red. The R15M will be available in Metallic Grey colour, additionally the R15M Monster Energy Yamaha MotoGP Edition has also been launched with MotoGP branding on the fairing, fuel tank, front mud guard and rear side panels, outlining Yamaha’s strong Racing DNA.

The 2021 YZF-R15 range adopts predominantly horizontal design lines like the YZF-R1, inheriting the DNA of Yamaha’s R-Series. As a result, the model looks sporty, while conveying a visual sense of stability in motion. To give it an imposing aura, the new YZF-R15 uses a single bi-functional Class-D LED headlight that also emphasizes the presence of the M-shaped intake duct.

The new YZF-R15 employs an upside down front fork with 37mm inner tubes, wherein the lower end (unsprung) is light, and the upper end (sprung) has thick outer tubes bolted to the chassis for higher rigidity. This new structure offers more stability under braking, with improved comfort and cornering performance. To accommodate the new front suspension, the upper triple clamp (handlebar crown) has been newly designed, with the rib shapes contributing to the strength–rigidity balance, similar to the M1.

The new YZF-R15 model is also the first small-displacement Yamaha motorcycle with manual transmission to feature Traction Control System, which controls the ignition timing and fuel injection volume to instantly adjust engine power output to avoid excessive slippage. It is also the first Yamaha single-cylinder motorcycle to feature a quick-shifter (standard on the YZF-R15V4 Racing Blue and YZF-R15M), for smooth, clutchless, upshifts.  It activates when speed is at or over 20 km/h, the engine rpm is at or over 2,000rpm, and accelerating.

The 2021 YZF-R15 range is powered by a 155cc, 4-stroke, liquid-cooled, SOHC, 4-valve engine that produces maximum power of 18.4 PS at 10,000rpm, with a torque output of 14.2 Nm at 7,500rpm. The fuel-injected motor with Variable Valve Actuation (VVA) is mated to a 6-speed gearbox.
