With the new pDrive primary clutch, it’s 30% quicker responding than the 800R E-TEC giving you the instant control you demand.REV PLATFORMNEXT GENERATION OF A LEGENDKey to the Summit’s agility is the extreme mass centralization of the 4th generation REV platform. The 850 E-TEC engine is compact and centered between the skis, making the vehicle easy to roll. The trademark pyramidal frame, new die-cast aluminum front suspension module and new heat exchanger design ensure it’s strong, yet lightweight.PDRIVE CLUTCHQUICK, EFFICIENT, EASYA major factor in the quickness of REV sleds is the new pDrive clutch.
