660R Raptor
Yamaha created a new benchmark for sport ATVs when it introduced the 660R Raptor. It utilized the largest engine to ever be placed in a sport ATV with the first 5-valve cylinder head in ATV history. The outstanding engine along with its YZ-spec, 5-speed manual transmission, state-of-the-art chassis and race-honed suspension helped the Raptor win the title of Sport ATV of the Year.
