The Ultramatic automatic transmission system is used in Yamaha’s toughest, most off-road capable ATVs and SxS vehicles including the Grizzly 700 ATV, Grizzly 550 ATV, Grizzly 450 ATV and Rhino 700 SxS vehicle.
Yamaha Motor Corp., U.S.A., has long touted its ATV and Side-by-Side (SxS) vehicles as being the toughest of their kind, and now a third party study conducted by ADP Lightspeed has proved that claim. More specifically, the ADP Lightspeed study shows that Yamaha has the most durable belt driven drivetrain in the industry.
“A lot of companies say they make the toughest ATVs, but now Yamaha can clearly prove that claim in our CVT transmission system,” said Steve Nessl, Yamaha’s ATV and SxS group marketing manager. “The ADP study proves once and for all that our vehicles have the best CVT drivetrain reliability in the industry.”
Yamaha’s claim is based specifically on an ADP Lightspeed competitive comparison study of Continuously Variable Transmission (CVT) belt components reported in warranty and non-warranty repair order records for 2007 to 2010 model year CVT belt-driven 4x4 ATVs with engines 400cc and above.
Yamaha’s reliable Ultramatic® automatic transmission system features an exclusive centrifugal clutch that allows the drive belt to remain under constant tension providing a key point of durability – something that sets it apart from competing models. Also exclusive to Yamaha’s Ultramatic system is the one way sprag clutch that not only aides in durability but provides the most natural feeling four wheel engine braking for maximum traction and rider confidence. This exclusive system is used in Yamaha’s toughest, most off-road capable ATVs and SxS vehicles including the Grizzly 700 ATV, Grizzly 550 ATV, Grizzly 450 ATV and Rhino 700 SxS vehicle.
