Yamaha releases mid-size ATV with power steering
29 Sep 2010
YMA is pleased to announce the release of the 2011 YFM450 Grizzly Auto 4x4 that features some major changes including the fitment of electronic power steering.
Engineered, tested and built tough, the key enhancements include a lighter one-piece frame, redesigned wet brake system, higher AC generator output and a more durable rear gear assembly.
These changes result in an overall weight reduction and improved ergonomics for a more comfortable and agile riding experience.
The Grizzly 450 has been a popular choice of professional and recreational riders since its introduction in 2005. It combines the versatility, durability and pulling power of a utility ATV with the handling and comfort that trail riding demands.
This year’s model retains the renowned features that set its predecessors apart from the competition. Like Yamaha’s push-button On-Command® drive system, which ensures solid driveability over varied terrain by allowing riders to rapidly switch between 2WD, 4WD or 4WD with differential lock. And, fully independent double-wishbone suspension at front and rear that maximises wheel contact over ruts and bumps to allow more traction and a smoother ride.
Like its big brother Grizzly 700, the Grizzly 450 incorporates the Ultramatic® transmission system. Yamaha's Ultramatic® transmission uses both a centrifugal and a sprag (one-way) clutch. This configuration minimises belt slippage by keeping the belt tight at all times, which increases the life of the drive belt. It also provides superior engine braking, allowing riders to tackle steep downhill gradients with confidence.
