Features may include:

• Final Edition Badging

A badge representing all 20,476 days Yamaha has been in the snowmobile business. May it spark many conversations about the best sled, the coolest innovation, the longest ride.

• YAMAHA MOUNTAIN SKI

The lightweight Yamaha Mountain Ski delivers everything you want in a deep snow ski. Its seven-inch-wide footprint enhances flotation and actively lifts the sleds nose up on plane in deep powder. Traction lugs on the top of the ski give you a sure foothold when the situation gets gnarly. The single keel design delivers light steering effort, yet confident and predictable handling on hard pack and in fresh fluff.

• MOUNTAIN SINGLE BEAM SUSPENSION

The long 12-inch travel rear suspension features a lightweight single-rail design for easy directional change with exceptional carving ability in the deep and steep. The advanced skid frame features a single pivot at the midpoint of the rail that runs down the centerline of the track. The single rail is over 10 pounds lighter by design and doesn't trap snow compared to conventional dual-rail suspensions keeping the sled much lighter in real-world conditions.
