- High mounted design helps prevent water ingestion
- Air box features a "no tools required" drain
-
Yamaha's industry leading Ultramatic® CVT (fully automatic) dual range transmission with reverse & downhill engine braking
- Dual range, high - low transmission with reverse. Low range offers more "grunt" for towing or hauling heavy loads or when tackling technical terrain
- CVT automatically selects the optimum transmission ratio, meaning you are always in the right "gear"
- Ultramatic® design offers controllable, confidence inspiring downhill engine braking
- Downhill engine braking also reduces brake wear & related servicing
- Ultramatic® design utilizes a special centrifugal clutch which keeps constant tension on the V-belt, reducing belt wear since the belt does not slip as the clutches engage
- High mounted belt cooling ducts help prevent water ingestion
- V-belt housing has an easy access "no tools required" drain plug
- Automotive style, gated, 5-postion shifter (high, low, neutral, reverse & park)
-
Convenient, handlebar mounted push button On-Command® 2WD - 4WD drive selector
