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.
Gearing and clutching specs - The Nytro models are designed to be ditch bangers and mogul play sleds, not lake runners. As such, they are clutched and geared for quick response and hard launches.
Camoplast Rip Saw™ track - The Camoplast Rip Saw™ track is a standard feature on the Nytro. 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.
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.
Fox FLOAT front shocks - Fox FLOAT shocks use a unique air spring design to force the piston to rebound. This eliminates the need for steel coil springs. They cut three pounds, as compared to traditional coil over springs. They are individually tunable by using a pocket-sized air pump, which comes with the sled.
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 Nytro corner.
ProActive™ CK rear suspension - The Nytro models use the ProActive™ CK torsion spring rear suspension. After extensive testing, the ProActive™ suspension delivered the best performance for playing through the moguls. Riders can preload the suspension at the base of road approaches or moguls and pop over them with a little squirt of throttle. The Nytro's ProActive™ is designated CK for its clicker-adjustable remote reservoir shock in the rear. Owners will have 20 clicks of compression damping adjustment to tune the best ride for themselves. The ProActive™ CK offers 11.5 inches of vertical travel.
Relocated, hooked bars - In order to give riders the best leverage and control in rough trail and pounded out ditches, the Nytro handlebars have been totally redesigned. They are taller, more forward and wider than ever before. In addition, they have hooks installed from the factory. The new location, in tandem with the rough trail seat, give the Nytro perfect ergonomics for aggressive bump playing. The Nytro handlebars are 3.5 inches higher, and farther forward than standard Vector-class machines. They measure just over 31 inches across, to give riders maximum leverage through the rough stuff.
Rough trail seat - The Nytro models have the tallest seats of the 2006 lineup. They have been specifically built for the hard-charging rider who likes to play in the beat up trails and not just scoot over the tops. The added height of the rough trail seat makes it even easier to go from sitting to standing. The rough trail seat still features the new roomy cargo space.
Standard electric start - Yamaha's electric starter system allows consumers to fire up their Nytro 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.
LCD gauge pod - The digital gauge pod on the Nytro 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.
Digitally controlled hand and thumb warmers - The Nytro'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.
