The drive system’s primary and secondary clutches are all new to accommodate a slightly different concept of function and a more simple—plus cost-effective—design to meet the performance targets for upshift/backshift and drive belt durability. The final drive system also employs a fully enclosed belt drive system in lieu of the traditional chain and sprocket encasement. The primary’s rollers act as a flyweight and use a stationary sheave with multi angles to control upshift. The secondary has a fixed helix with composite rollers on a moveable sheave acting on an adjustable torsion spring. Braking power is provided by a Hayes single piston hydraulic caliper that clamps down on a vented rotor mounted directly to the track drive shaft.
The chassis is stamped from lightweight aluminum with relatively wide running boards opened up to aid in snow diffusion. The front suspension is A-arm and coil-over shocks with 4.5 inches of travel and the rear skid has a twin-tube emulsion coil-over shock along with a cam adjustable preload torsion spring, also good for 4.5 inches of travel.
Yamaha designed the tapered tip ski and Camso built the 10x90x1-inch Cobra track for the go-ability of the SnoScoot.
Back in January when the SnoScoot was first introduced, an MSRP was not released but Yamaha officials said it was important that the sled be less than $4,000. The company exceeded its goal by giving the SnoScoot an MSRP of $3,799.
