BRP’s 2015 Ski-Doo MXZx 600RS builds on its strong chassis performance from 2014 by refining the engine and drive systems for better power delivery and even better overall durability.
Last season saw big chassis changes for the Ski-Doo stock terrain racing sled, including new front suspension, new steering and longer 128 in. (3251 mm) track that gave racers a well balanced, easy to handle and extremely durable platform. This season the Valcourt Race Shop concentrated on getting more power out of the engine and transferring that to the snow for better starts and corner-to-corner acceleration.
Improvements come from a one-pound lighter crankshaft that allows the engine to build RPM faster and calibration changes in the ignition and fuel mapping for a stronger mid range pull. New software programs developed in late season testing and Open Mod engine development have also yielded better consistency in changing temperatures and humidity.
Working in conjunction with the engine changes will be a new track design that incorporates a new lug pattern for better acceleration.
