A Yamaha Raptor 660R is capable of reaching a top speed of between 80 and 95 miles per hour. The vehicles have an electrical limitation that prevents them from travelling faster than 100 mph.
A liquid-cooled, 660 cubic centimetre engine powers the four-wheeled all-terrain vehicle. The Raptor 660 has the largest ATV engine on the market when it was initially released in 2001. It had a four-stroke engine and was made to handle different terrains. The Raptor 660 was offered until 2005, and the Raptor 700R took its place in 2006.
