Bombardier Recreational Products, Inc. [BRP] made a significant advance in entry level-snowmobile racing last season with the move of Ski-Doo fan-cooled models to the revolutionary REV platform, and two accessory kits that upgraded the sleds for competition.

With the introduction of the 2006 MX Z Fan 550X model, the company is kicking entry-level racing up another notch. With its REV platform, SC-4 rear suspension, and driveline nearly identical to the new 2006 MX Z 440 racer, the MX Z Fan 550X is a formidable sled.

Add the new 550X Racing Kit upgrade package (P/N 860 429 100) and you’ve got a sled that is completely race-ready. The kit has three major upgrades: upgraded shocks, upgraded clutching and stronger rear suspension wheels, along with bits and pieces to install the package. Some racers will also want to switch to the 1.25-inch track (P/N 504 152 483) for extra holeshot traction.

In terms of shocks, the kit includes C-36 Racing-Clicker Aluminum Take-Apart racing shocks on the rear suspension – the same shocks as on the 440 – and HPG Aluminum Take-Apart piggyback shocks in the front. All shocks are calibrated for snocross racing, but for lighter riders.

A collection of clutch springs, clutch weights and new belt improve acceleration, holeshots and backshifting.

The kit is available now at Ski-Doo dealers, with a MSRP of $1479.97 USD/ 1749.97$ CDN.
