Comfort

• Lightweight with a tall and narrow profile, the M-TX mountain seat is both shorter and more tapered towards the front than our standard trail seat. This allows for easier rider transitions from side to side, and improved stand-up ergonomics. Included in-seat electric heat element for additional comfort in the cold and wet. Additional storage is provided by a convenient under-seat bag. The semi-rigid design is easy to access and water resistant to keep your spares safe and dry. Quarter-turn, quick release fasteners are provided to make removal a snap.
• The Sidewinder's generous 8.9-gallon fuel tank serves more purposes than just carrying a day's worth of fuel. It also cradles the battery and is the platform for the quick-release trail seat. The ever-changing fuel load is carried low and rearward, helping centralize the overall mass and balance of the sled.
• Convenient handlebar positioning makes shifting to and from reverse easy with just the push of your thumb. A servo motor shifts the drivetrain into reverse simply and consistently. An audible warning beeper reminds you when you are still in reverse.

Handling

• The sleek SRV-M front suspension is ultra-compact to reduce unwanted spindle and suspension component drag in deep snow. The narrow stance allows for extreme maneuverability and delivers aggressive lean angles for incredible side-hilling and powder turn capabilities. The lightweight, forged aluminum spindles join the widely spaced upper and lower control arms producing a large caster angle for tight side-hilling and ease of steering.
• The pyramidal upper frame creates chassis strength without excessive weight. Additional bracing is added to the 'punched' running boards for those who tend to take their ride to the max.

Performance

• Yamaha engineers wanted an engine that's exceptionally quick to respond with little or no 'lag' as found in a conventional turbo. It’s an innovation not seen in any other production turbo on the planet, and another first for Yamaha with the Genesis turbo.
• Unlike conventional turbo 'blow-off' valves, the Yamaha ABV redirects air pressure back into the intake side of the compressor to prevent surge and help maintain impeller speed, resulting in ready acceleration and seamless power delivery.
• The YSRC primary and roller secondary clutches are calibrated for durable, cool operation. They harness and transfer the massive torque produced by the Genesis turbo efficiently to the track while minimizing drive belt wear. The primary shifts out aggressively to use all the power on tap while the roller secondary is quick to back-shift and provides additional ratio through its oversize sheaves to keep accelerating long after the others have signed off.
• The lightweight, forged aluminum spindles join the widely spaced upper and lower control arms producing a large caster angle for tight side-hilling and ease of steering. The clean, narrow overall stance and elimination of the sway bar also greatly enhances deep snow agility.

Top Features

• 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.
• 998CC GENESIS ENGINE: The 998cc Genesis turbo-boosted triple powerplant is unmatched when it comes to delivering incredible power with the refinement and quality you have come to expect from a Yamaha. Designed around a premium turbo unit, every engine component from intake to exhaust is dedicated to producing uncompromised performance. The proven Yamaha turbo has earned the respect and reputation befitting the industry's highest achiever. This engine is virtually the potent venom of the Sidewinder's bite.
• SRV-M SUSPENSION: The sleek SRV-M front suspension is ultra-compact to reduce unwanted spindle and suspension component drag in deep snow. The narrow stance allows for extreme maneuverability and delivers aggressive lean angles for incredible side-hilling and powder turn capabilities. The lightweight, forged aluminum spindles join the widely spaced upper and lower control arms producing a large caster angle for tight side-hilling and ease of steering.
• The lightweight Yamaha Mountain Ski delivers everything you want in a deep snow ski. Its wide footprint enhances flotation and actively lifts the sled’s nose up on plane in deep powder. Traction lugs on the top of the ski give you a sure foothold when the situation gets really gnarly. The wide and deep keel design delivers light steering effort, yet confident and predictable handling on hard pack and in fresh fluff.
