For 2017 Ski-Doo introduces their 4th generation REV platform, taking snowmobile performance to new heights yet again. Key to delivering on this promise was something BRP hadn’t done in more than 20 years – developing the snowmobile platform and engine together. The team created a narrow powerpack in the all-new Rotax 850 E-TEC twin and centered it laterally in the chassis. This centralizes and centres the masses dramatically for more responsive handling and enables a radical narrow ergonomic enabling rider agility.
The main technical advancements with the fourth generation of REV and Rotax 850 E-TEC sleds are:
Masses have been dramatically centralized laterally. Designing the powerpack very narrow further centralizes the sleds’ greatest mass, making them more responsive to rider input – whether it’s on a tight trail corner or a technical deep snow carve. The new 850 E-TEC II powerpack is centered laterally in the chassis – so that the same effort is required turning left as right. In fact, side-to-side weight distribution is 50/50.
New ergonomics unlock even more rider potential. Snowmobiles’ handling and agility is greatly influenced by “Body English,” so the team focused intensely on enabling riders to do more, but also ride the sled different ways. There is a lot more room to move with the narrow design, both side-to-side and front-to-back. When you combine the ultra-responsive, mass-centered platform with so much room to move, riders can easily find the riding style that works for them.
Specialized features for specialized riding styles. While the MXZ, Renegade and Summit sleds share many components, each sled is specialized for its use. The MXZ and Renegade feature a flat footrest, trail-specific side panels, open toe-holds for cornering and X-package models feature a more precise rack steering system. Summit sleds are tailored for deep snow riding with powderdynamic body panels, open running boards, an open tunnel cap and new track designs.
