The new transmission for 2002 was the last major upgrade the mighty 660 would get before its replace- ment in 2006, when Yamaha shocked us again with an
all-new, fuel-injected Raptor 700. Yamaha wasn’t satisfied
with just adding cc’s and fuel injection. The 2006 Raptor
700 was a completely new animal. A state-of-the-art chassis was introduced, consisting of extruded and cast aluminum, combined with conventional, round steel tubing.
This new chassis received an all-new larger-displacement
(686cc) motor that was fed by the latest-technology EFI.
Yamaha’s new Raptor 700 would also share a very similar (and interchangeable) front end with the race-proven
YFZ450. The 2006 Raptor 700 front end came equipped
with basic, non-rebuildable coil-over shocks and was later
updated to higher-end, adjustable piggyback models. Over
the years the Yamaha Raptor has become quite the crowd
favorite, and the aftermarket has found many ways to
The 2001 Yamaha Raptor 660 instantly became the top big-bore four-stroke sport quad. The Yamaha Raptor used a completely new sport-inspired ATV chassis, with a 660cc, single-cylinder,
four-stroke engine derived from a European Yamaha
dual-sport motorcycle. The monster-bore Raptor was
an instant success, and dealers were selling them like
mad. The 2001 Raptor had one major oversight—
the transmission was straight from the motorcycle
engine and quickly proved under-built for the heavier
ATV application. Second gear was problematic, and
Yamaha beefed up the entire transmission for 2002.
This ’02-and-later transmission became a must-have
upgrade for anyone riding an ’01 Raptor aggressively or
pumping up the performance.
