Performance
The Genesis 120 engine is compact and lightweight. Its long stroke and four-valve design produces a tremendous amount of torque for corner-to-corner acceleration on the trail. The broad torque curve is easy for clutch tuners to hit and allows riders to have instant power after backshifting. The three-cylinder engine debuted in 2005. Instead of using a gear reduction, the Genesis 120 engine has the primary clutch directly attached to the crankshaft. This reduces parts, complexity and weight, resulting in a great product for consumers. It also allows the engine to be mounted deeper in the chassis to deliver a lower center of gravity, further enhancing the sled’s cornering stability. The YVXC primary spins at 8500 RPM to transfer power from the engine to the secondary and on to the track.
The Camoplast Rip Saw track is a standard feature on the RS Rage GT. 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 is the result of a collaborative effort between Yamaha and Camoplast. The exhaust is routed out the back of the sled in order to optimize and maximize airflow through the engine. The tuned system is specifically engineered to produce the Genesis 120’s broad powerband and also to help keep the sled in balance. The lightweight 4-piston brake system delivers solid stopping power without fading, even in high-use applications. It also incorporates a lightweight, double-finned, self-cooling brake disc. The forged pistons used in the Genesis 120 engine are engineered for lightweight and still allow high compression rates of 11.3:1 on 87 Octane gas. The piston design came out with the Genesis 120 engine on the Vector™-class sleds.
The geometry of the second generation front suspension features short spindles and long A-arms. The suspension was engineered to deliver excellent cornering stability and consistent turning effort throughout its travel stroke. It delivers 9 inches of vertical travel and sets the skis at 42.7 inches. Steering is consistent, because the spindles are maintained at a constant 23 degrees.
The GYTR™ piggyback shocks on the RS Rage GT’s front suspension offer 12 clicks of compression AND 20 clicks of rebound adjustability for maximum tuning ability. The piggyback reservoir offers increased fade resistance to the shock. Yamaha incorporated liberal usage of ultra-lightweight magnesium material wherever possible to reduce weight on engine componentry. The use of magnesium became widespread on all Genesis-class engines. The Deltabox chassis is designed specifically to house the Genesis engine family. It supports the engine and utilizes it in forming one of the most rigid chassis on the market. The more rigid the chassis, the more consistent the sled will handle. Yamaha’s Controlled Flow casting technique is used for many of the structural pieces on the chassis. The CF process draws the molten metal into the mold under a vacuum, reducing the formation of air bubbles in the material. As a result, pieces can be made much thinner and still deliver the strength characteristics of a conventionally cast, thicker piece. The saddleless plastic ski reduces unsprung weight and its aggressive keel design provides strong bite to help the RS Rage GT corner.
Comfort The Mono Shock RA 136 cuts an amazing 12 pounds off of the ProAction™ 136 suspension formerly used on the RX Warrior™. Like the 121-inch version, the 136 offers riders a full 20 clicks of compression adjustment on the 46mm aluminum HPG shock. The dial is located on the left of the tunnel, near the rider’s leg for easy access from the seat. The Mono Shock RA 136 delivers 11.7 inches of vertical travel. The lightweight seat is tall enough to allow riders a clear vantage point to scan the trail in front of them while maintaining a very traditional riding position. It also affords added comfort for a long day’s journey. The RS Rage GT’s hand and thumb warmers have been consistently rated among the best in the industry. They are individually-controlled, with the settings shown on the digital gauge so that riders can see them. Owners can choose from 10 settings on the grips and 10 settings on the thumb warmers, as opposed to the hi/lo settings of most other sleds on the market.
Yamaha’s electric starter system allows consumers to fire up their RS Rage GT with the turn of the key. There is no pulling on a nylon cord to get this high-tech engine growling! Electric start has been a standard feature on all of Yamaha’s 4-stroke machines. The digital gauge on the RS Rage GT allows the driver to see engine RPM and track speed data at a glance. The gauge also displays heater settings, fuel level, engine temperature and odometer. Yamaha digital gauges have become a benchmark in the industry. The digital readout has been copied by the competition almost across the board. The RS Rage GT’s tall windshield offers excellent protection from cold wind and snow spray on long trail rides.
