Vehicle Information
Yamaha Raptor 660 ATV (2001-2005)
The Yamaha Raptor 660, produced from 2001 to 2005, was a prominent sport ATV renowned for its powerful engine and agile handling. It featured a 660cc single-cylinder, five-valve, liquid-cooled, 4-stroke engine, delivering approximately 36 horsepower. This engine was equipped with dual Mikuni 33mm carburetors and paired with a five-speed manual transmission that included reverse. The primary model was the Raptor 660R (YFM660R), with Limited and Special Editions offered in 2004 and 2005 respectively. While the core engine remained consistent, Yamaha introduced notable refinements throughout its production. Early 2001-2002 models were known for starter clutch issues. By 2003, Yamaha addressed feedback with a reinforced rear axle carrier and crucial frame reinforcements. The 2004-2005 models are often considered the "sweet spot," benefiting from improved suspension and gearing tweaks that enhanced overall rideability and performance.
