Engineered to your bike's natural feel, the Mototrax snow bike conversion system is the most advanced kit on earth. Our track system is equipped with a single shock, rising-rate suspension, just like your dirt bike. Add in 12.5 degrees of lateral articulation and you have the most responsive and nimble snow bike on the mountain. For the 2019 model year we increased the durability of our system by adding more rail support without compromising weight and improved stress point strength on the bulkhead. We added grease zerks on all pivot points to keep your system functioning at optimum levels without doing full tear-downs on the skid, keeping you on the mountain and out of the garage. Our whole lineup received brand new rear A-arm technology, with the Enduro.120 and the Mountain.129 gaining our new EDS (Elastomer Damping System) for improved feel and performance in all conditions. The MTX.120 and MTX.129 Factory Edition models take performance one step further with the all-new IDS (Intelligent Damping System), taking snow bike performance to new levels. Here at Mototrax we didn't take existing snowmobile technology and make it work for a dirt bike. We designed a snow system that rides and feels like a dirt bike.
