Features ROTAX 600R E-TEC ENGINE: Following its big brother Rotax 850 E-TEC engine's lead with second generation E-TEC technology, the Rotax 600R E-TEC engine offers a 30% improvement in throttle response**, crisp acceleration and sets a new 600cc class standard with 125 horsepower* while continuing to set the bar for reliability, and 2-stroke oil and fuel economy. *Observed HP metric based on internal dyno test in optimal conditions. **Based on internal engineering testing compared to 600 H.O. E-TEC. PDRIVE CLUTCH: A major factor in the quickness of REV sleds is the new pDrive clutch. Fast and friction-free dual rollers transfer torque in place of traditional sliding buttons on this 100% clutch. The oversize rollers with needle bearings, wide flyweights and shaft-on-shaft design emphasize smooth operation and long life. Ultra-responsive shifting, impressive RPM consistency and 2.8 lb. (1.3 kg) lighter than the TRA VII. REV GEN4 PLATFORM: The 4th generation of the REV platform is designed around aggressive trail riders with a narrow, compact package giving the rider more freedom to move and influence the sled. More centralized masses (especially side-to-side), light weight and industry-leading suspensions make the vehicle ultra responsive. RAS 3 FRONT SUSPENSION: Precise, predictable handling and outstanding bump absorption, even in harsh conditions, with state-of-the-art unequal length A-arm front suspension. RMOTION REAR SUSPENSION: Provides more capability, more comfort and more adjustability. Separate spring and shock dynamics combine with the most rising-rate/progressive motion ratio in the industry to give the rMotion suspension a supple ride in small bumps with added capability in large ones. And there’s no need to be a suspension guru to enjoy the ride – with its broad sweet spot, you can set it up once and it will perform impressively in nearly every condition.
