Performance

3-cylinder Genesis 120™ engine
The RS Vector® Mountain SE is powered by the lightweight, compact Genesis 120 engine. 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 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.

16x162x2.25-inch Camoplast Maverick track/extrovert drive sprockets
Yamaha and Camoplast collaborated in the design of the Maverick track. The 16x162x2.25-inch track features a 3-degree 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. Churning the track is a pair of factory-engineered extrovert drive sprockets. The engineering team purpose-built these sprockets to work with the Maverick track and reduce vibration.

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 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 Vector™-class sleds.

Handling

Single-taper mountain tunnel
To accommodate the 16-inch wide track, the RS Vector Mountain SE needed to have a different tunnel. The single-taper design is lighter than previous mountain tunnels. It features a straight angle for simplicity and rapid snow elimination. In addition, the runningboards are wide with aggressive star-punched traction along their length. Overall, the single-taper mountain tunnel is 140mm longer than previous mountain tunnels.

Adjustable width second generation front geometry
The second generation geometry on the front end of the RS Vector Mountain SE uses the same short spindles and long A-arms as the trail Vector machines, but adds an adjustable width feature to allow owners to set the skis at the desired width. In addition, the configuration maintains spindle castor at 23 degrees throughout the travel stroke. This gives the sled consistent and predictable steering regardless of the suspension’s activity.

Aluminum HPG front shocks
The High Pressure Gas (HPG) shocks on the RS Vector Mountain SE’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.

Magnesium chaincase
The RS Vector Mountain SE features a lightweight magnesium chaincase. The exotic material cuts a pound from the previously used aluminum chaincase on other models.

Mountain skis
The saddleless plastic mountain ski is wider than a trail ski with a deep keel for excellent powder-handling characteristics. The unique arched fin design of the ski aids in powder handling and also deflects snow away from the sled and the driver.

Comfort

ProMountain™ 162 rear suspension
The lightweight ProMountain rear suspension is a more conventional torsion spring design. It was engineered to help the sled get up on plane in the fresh snow. It does this through weight transfer and shallow track approach angle. The dual-angle rails also give the RS Vector Moutain SE excellent trail manners, while maintaining its deep snow floatation. The ProMountain 162 delivers 14 inches of vertical travel. The rear idler wheel is elevated 25mm, thanks to the dual-angle rail design.

Large rear rack
The RS Vector Mountain SE sports a large rack on the end of its lengthened tunnel. The design incorporates a high-visibility LED taillight in the back. The rack measures 11.8x15.75 inches.

Tall, lightweight mountain seat with large rear rack
The seat on the RS Vector Mountain SE is taller and lighter than on a trail sled to suit the mountain rider’s unique needs. The seat uses superlightweight, yet firm foam for its height. In addition, the lightweight seat includes a storage trunk in the rear, with expanded capacity and accessibility. In addition to the seat storage, the RS Vector Mountain SE also features a large rack on the end of the tunnel. The design incorporates a high-visibility LED taillight in the back. The rack measures 11.8x15.75 inches.

Wide, hooked handlebars with new center grab strap
To match the tall and forward position, a taller and wide hooked handlebar is standard fare on the RS Vector Mountain SE. The design incorporates aftermarket-style, keyed slot hooks on both sides to eliminate unwanted hook rotation. The hooks have the same grip material as the main bar section, for more consistent control, regardless of hand position. Mountain riders will appreciate the new, stiffer and shorter center grab strap when it’s time for sidehilling. The new mountain bar location is an inch taller than the ‘06 mountain handlebars.

Wide runningboards with traction
The runningboards on the RS Vector Mountain SE are wide with aggressive star-punched traction along their length. The traction design will allow some snow and slush buildup to drain off the boards for added footing confidence.

Standard electric start
Yamaha’s electric starter system allows consumers to fire up their RS Vector Mountain SE with a 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.
