The top speed of a Yamaha R1 motorcycle is 186 miles per hour. Introduced by the Japanese Yamaha Corporation in 2014, the R1 has a 998cc, liquid-cooled, 16-valve engine and a 6-speed transmission. The die-cast aluminum chassis is very light, strong and flexible to maximize speed and performance.
Many other attributes contribute to the Yamaha R1s exceptional speed, such as the custom Yamaha Chip Controlled Throttle and the Yamaha Chip Controlled Intake, which facilitates throttle-response and the resulting fuel injection. The intake valves are constructed of lightweight - but very strong - titanium, and the 7-level traction control system makes taking sharp corners at high speed easier.
