2012 Yamaha FX NYTRO MTX 153
- High Performance 4-stroke engine
The over-achieving High Performance engine is the heart of our lightweight, high performance and aggressive FX Nytro model family. It has dominated its class at the Old Forge Shoot-Out 2 years straight, claiming top speed twice and posting the best average ET over 4 runs down the ¼-mile track.
- Advanced fuel injection
The High Performance engine uses Yamaha’s advanced fuel injection system to control fuel flow to the engine. Consumers will enjoy the engine’s spot-on performance and throttle response as a result of the advanced electronic fuel injection system.
- Engine braking reduction system
The High Performance engine features the unique Engine Braking Reduction System. The system allows a small amount of air to pass through the fuel injection system when the throttle is released, giving riders a “coast” feeling.
- Lightweight rear-exiting exhaust
The patented rear exit design serves many performance-enhancing functions on the FX Nytro MTX 153. First, it maximizes horsepower by using a straight exhaust pipe design. Second, it reduces the amount of under-hood heat produced. Third, the rear-exiting design distributes weight to contribute to the excellent balance of the sled.
- Forced air radiator ducting
The FX Nytro MTX 153’s airflow design pulls fresh air in from around the headlight and forces it through the radiator fins for high cooling capacity, resulting in consistent engine performance even in low-snow conditions.
- 15 x 153 x 2.25-inch Single-ply Camoplast® Maverick™ track
Yamaha and Camoplast® collaborated in the design of the Maverick™ track. The 15x153x2.25-inch track features a 3-inch pitch to allow more snow to pack in between the lugs for a firmer grip on the snow. Also, the lugs are extremely varied in design and profile for even more traction in multiple snow conditions.
- New single-piece extrovert drive sprockets
Churning the track is a pair of new single-piece extrovert drive sprockets. The engineering team purpose-built these sprockets to work with the Maverick™ track, reduce weight from the previous sprockets, and decrease vibration.
