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. 7.2 IN. WIDE DIGITAL DISPLAY: All-digital LCD gauge with customizable display with flatter viewing angle provides riders their preferred info that’s easy to see sitting or standing. 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. KYB PRO SHOCKS: Designed to the same high standards as the MXZx 600RS race sled - so you know they're extremely capable and durable for control in the toughest conditions. Remote reservoir design for performance and they are rebuildable/revalvable. Easy Adjust compression damping knob requires no tools; rebound adjustments are standard on front shocks also. RS RUNNING BOARDS: Designed for aggressive stand-up riding, they are flatter for most of their length, wider and strong. Thicker aluminum sheet (3 mm vs. 1.8 mm), plus front and rear reinforcements to withstand tough landings.
