Performance

3-cylinder Genesis® 120 4-stroke engine The smooth-running 120hp-class Genesis 120 triple has proven itself one of the most reliable engines in all of the sport. Its broad power curve and excellent fuel economy have earned this carbureted classic a strong following among high-mileage enthusiasts. The Genesis 120 keeps pulling hard once it gets into the peak performance zone. Competitive 2-stroke engines fall off as soon as they achieve their peak horsepower. The three-cylinder engine debuted in 2005. Direct-to-crankshaft clutching Instead of using a gear reduction, the Genesis 120 engine has the primary clutch directly attached to the crankshaft. This eliminates parts, complexity and weight, resulting in a better product for consumers. It also allows the engine to be mounted deeper in the chassis to help centralize mass, contributing to the sled’s excellent flat-cornering capabilities. The YVXC™ primary spins at 8500 RPM to transfer power from the engine to the secondary and on to the track. 15x136x1.25-inch Camoplast® Rip Saw™ track The Camoplast® Rip Saw™ track is a standard feature on the RS Vector LTX. 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. It first appeared on the 2004 4-stroke models. Rear-exiting exhaust 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. Lightweight hydraulic brake system The lightweight 4-piston brake system delivers solid stopping power without fading, even in high-use applications. It also incorporates a new, lightweight, double-finned, self-cooling brake disc. Lightweight forged pistons 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 2005 Vector-class sleds.

Handling

Deltabox™ II with comfortable rider-forward position The primary design objective of the Deltabox II chassis was to create a comfortable rider-forward posture. The ergonomic treatment is achieved by locating the handlebars and seated position high and forward on the chassis. With this positioning, the rider can go from sitting to standing and back again easily and comfortably. It also further centralizes the combined mass of sled and driver, for razor-sharp handling. Second generation front suspension geometry 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. Integrated airbox/small hood The design on the RS Vector LTX is very efficient, often integrating many functions into one component. One such example is the use of the airbox as a part of the hood design. The upper element, closest to the headlight, is comprised of the silencer cover for the airbox. This design feature allows for a very small hood piece, which keeps weight low. Magnesium valve, crankcase and oil pump covers Yamaha incorporated liberal usage of ultra-lightweight magnesium material wherever possible to cut weight on engine componentry. The use of magnesium became widespread on all Genesis-class engines in 2005. Tall, wide, hooked handlebars To match the tall and forward position, a single-piece, dual-hooked handlebar is standard fare on the RS Vector LTX. The hooks have the same grip material as the main bar section, for consistent control, regardless of hand position on the grip. Saddleless plastic skis The saddleless plastic ski offers low unsprung weight and its aggressive keel design provides strong bite to help the RS Vector LTX corner.

Comfort

Mono Shock® RA 136 rear suspension The Mono Shock RA 136 is a specifically-engineered expansion of the successful Mono Shock RA 121-inch version found on other Yamaha sleds. It uses a single shock and coil spring to control the sled’s travel. Like the shorter version, the Mono Shock RA 136 features a remote adjustment dial with a full 20 clicks of compression adjustment on the 46mm aluminum HPG shock. Consumers will enjoy a comfortable ride at both low and high speeds. The Mono Shock RA 136’s adjustability will allow owners to easily tune the amount of shock dampening that suits their style. 36mm KYB® aluminum HPG front shocks The 36mm KYB® High Pressure Gas (HPG) shocks on the RS Vector LTX’s second generation front suspension geometry deliver consistent performance with excellent fade resistance. Tall, lightweight seat The RS Vector LTX seat has been specifically built for the hard-charging rider who likes to ride in the beat-up trails and not just scoot over the tops. The lightweight seat features a roomy cargo space. The height of the rough trail seat makes it even easier to go from sitting to standing, while the firm foam provides extra comfort. In 2008, it features a color band to match the sled’s lines and red graphics. Wide runningboards with star-punched traction The RS Vector LTX’s wide runningboards feature star-punched traction throughout their entire length. The boards also have an outer traction roll for additional sure footing. As an added benefit, the traction holes help evacuate snow and slush from the runningboard, delivering additional confidence and comfort. Digital gauge with extensive data features The RS Vector LTX features a digital gauge array that displays a wide variety of data. Readouts include barometric measurements, dual trip meters and a clock. In addition to the functions, the gauge has been styled to match the aggressive lines of the body work and console area. Standard electric start Yamaha’s electric starter system allows consumers to fire up their RS Vector LTX with the turn of a key. There is no pulling on a nylon cord to get this high-tech engine growling! Electric start is a standard feature on all of Yamaha’s 4-stroke machines.
