Grizzly’s Ultramatic® transmission features a gated shifter plus reverse gear, and is the most advanced—and durable—CVT drive system available. An automatic centrifugal clutch maintains constant belt tension for reduced belt wear and a sprag clutch delivers natural all-wheel engine braking. Fully sealed drive case keeps out water and debris to minimise belt slippage, and a no-tools side cover drain makes it a snap to get rid of what little does sneak in.
