BRP introduced a redesigned 2018 Ski-Doo MXZx 600RS E-TEC racing snowmobile, designed for North American and European snocross tracks, during the 51st annual Haydays in Minnesota this past weekend. The 2018 MXZx 600RS E-TEC is based on the REV Gen4 platform for superior rider ergonomics and handling in rough conditions.
Like all Gen4 sleds, the narrow design featuring centralized mass is agile and responsive while the Ergo Step side panels and beveled tunnel gives racers enormous freedom to ride the way they want - without interference from the chassis. Other features unique to the racing sled include a tilted tunnel with short heat exchanger, new motocross inspired seat, racing footholds and a small fuel tank.
The RAS 3 front suspension with unique steering system provides ultra precise handling with less effort so racers can concentrate on choosing the best lines. To further assist precise steering the sled is equipped with the new lightweight Pilot R2 skis that were race tested last year by top pros Tim Tremblay and Lincoln Lemieux.
One thing familiar will be the Racing rMotion skid frame in back — but it too receives some major upgrades. There’s a new KYB piggyback 46mm center shock, new motion ratio and calibration for the rear shock, and lighter weight components throughout.
The very special — for racing only — Rotax 600RS E-TEC engine is also all-new for 2018, with more horsepower and extremely fast dynamic response racers will appreciate. E-TEC direct injection makes its racing debut and combined with the booster injectors first deployed on the Rotax 850 E-TEC, delivers that quick response and contributes to the overall power gains. Other ideas adapted from the 850 for this specialty engine include a shorter intake tract with double reeds, digital eRAVE and lightweight exhaust system. The 600RS E-TEC also gains a little more displacement as it grows to 599.4 cc. The updated powerpack was completely reconfigured to fit in the efficient REV Gen4 platform.
