FX Nytro RTX

Genesis® 130FI 4-stroke engine
The over-achieving Genesis 130FI 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. The advanced fuel injection keeps the 3-cylinder engine running at maximum 130 horsepower-class performance.
Advanced fuel injection
The Genesis 130FI 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 Genesis 130FI 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 RTX. 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 RTX’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.
15x121x1.25-inch Camoplast® Rip Saw™ track
The Camoplast® Rip Saw™ track is a standard feature on the FX Nytro RTX. It has been widely acclaimed in the industry as the best all-around OEM track for acceleration, cornering bite and everyday trail usage. The Rip Saw™ track development is the result of a collaborative effort between Yamaha and Camoplast®.
