Yamaha YZF-R15rnrnYamaha also modified the suspension setup on the 2021 R15 V4.0 with included US dollar front forks. The units replace the telescopic forks seen in V3.0. The 37mm forks have a lighter lower end (no suspension), while the thicker outer tubes (springs) are bolted to the upper end of the chassis for added stiffness. Yamaha says the new chassis provides more stability during braking while improving comfort and cornering performance.rnrnTo accommodate the new front suspension, the bike receives a new triple top buckle (the handlebar crown) with rib shapes that contribute to a balance of strength and stiffness, similar to the M1. The new R15 now also comes with traction control, along with a standard quick-change transmission in the R15 V4 Racing Blue and R15M colorways. It operates at speeds above 20 km / h or when the motorcycle exceeds 2000 rpm and is accelerating. The model also has a slipper, an auxiliary handle, and a dual-channel ABS.rnrnThe 2021 YZF-R15 and R15M continue to draw power from the liquid-cooled SOHC 155cc four-valve four-valve engine producing 18.1 horsepower at 10,000 rpm and 14.2 Nm of peak torque at 7,500 rpm. Power is just below V3.0, while torque is 0.1Nm. The fuel injection engine with variable valve operation (VVA) is mated to a six-speed gearbox. The bike has a curb weight of 142 kg.rnrnMeanwhile, the R15M is distinguished by its special seats, a 3D logo, and new ByBre brake calipers. Both bikes come with a new LCD console with Bluetooth connectivity. There is also a new information/trip button on the right side of the steering stem that allows access to different visual modes: track and street. Yamaha also claims a drag coefficient of less than 0.293 cd on the new R15 range.rnrnAlso Read: Hero MotoCorp working to launch retro-style Harley-Davidson model
