3-cylinder Genesis 120™ engine - 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.
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 deliver a lower center of gravity, further improving 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.
Camoplast Rip Saw™ track - The Camoplast Rip Saw™ track is a standard feature on the RS Vector ER. 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.
Second generation front suspension geometry - The geometry of the second generation front suspension features shorter spindles and longer A-arms. The suspension was engineered to deliver greater cornering stability and also more consistent turning effort throughout its travel stroke. The second generation front suspension geometry debuted on the 2005 Vector-class sleds. 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.
Aluminum HPG front shocks - The High Pressure Gas (HPG) shocks on the RS Vector ER's second generation front suspension geometry deliver consistent performance with excellent fade resistance. They are rebuildable and rechargeable for years of quality service.
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.
Ultra-rigid Deltabox™ chassis - The Deltabox™ chassis is designed specifically to house the Genesis™ engine family. It supports the engine and utilizes it in forming the most rigid chassis on the market. The more rigid the chassis, the more consistent the sled will handle.
CF die cast construction - 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, eliminating 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. Yamaha started using the CF process on the 2003 RX-1.
Saddleless plastic skis - The saddleless plastic ski reduces unsprung weight and its aggressive keel design provides strong bite to help the RS Vector ER corner.
Mono Shock™ RA rear suspension - The Mono Shock™ RA rear suspension uses a single shock to control the travel of the skid. The shock is remotely adjustable via a rotating dial located conveniently on the left side of the tunnel, near the driver's leg. The suspension is widely adjustable to suit nearly any rider in nearly any condition. In addition to the remote adjustment, the Mono Shock™ RA is also adjustable at the coil spring and at the control rod.
Wide runningboards with star-punched traction - The RS Vector ER's wide runningboards feature star-punched traction throughout its entire length. The boards also have an outer traction roll for additional sure footing in any riding condition. As an added benefit, the traction holes help evacuate snow and slush from the runningboard, delivering additional confidence and comfort.
Tall seat - The seat is tall enough to allow riders a clear vantage point to scan the trail in front of them. It also affords added comfort for a long day's journey. The tall RS Vector seat debuted in 2005.
Digitally controlled hand and thumb warmers - The RS Vector ER'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 ten settings on the grips and ten settings on the thumb warmers, as opposed to the hi/ lo settings of most other sleds on the market.
Standard electric start - Yamaha's electric starter system allows consumers to fire up their RS Vector ER with the turn of a 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, dating back to the original RX-1 in 2003.
LCD gauge pod - The digital gauge pod on the RS Vector ER allows the driver to see key data at a glance. Either tachometer or speedometer readings can be displayed digitally, with the other appearing on the sweep gauge. The gauge also displays heater settings, fuel level, engine temperature and odometer. Yamaha offered the first digital gauge cluster in 2002 on the SX Viper. Since then, it has become a standard of the industry. The digital readout has been copied by the competition almost across the board.
