With three model choices, there is a Mountainhorse kit for everyone. Our experience is that the ST is the most bang for the buck and an outstanding choice for Midwestern riders! Also a great choice for out west, too, as the shorter track allows more engine RPM and great maneuverability in tight situations.

The ST (Short Track) kit is our standard and most popular snow bike conversion kit. It includes a 120” long track that is 12.5” wide with 2” tall paddles. This kit provides the best maneuverability and control for mountain riding along with the best power to traction ratio to utilize the power of a dirt bike as small at 250cc. However we have found that the 450cc motocross bikes have the best power to weight ratio out of all dirt motorcycle classes.
The kit provides plenty of storage space on the tunnel for gas can and cargo bags to pack all your needed gear.
The LT (Long Track) kit is the same as the ST but with a longer track. The kit offers a 137” long track that is 12.5” wide with 2” tall paddles. This kit provides 20% more traction in deep snow over the ST kit and will give you a more secure feeling on a steep side hill allowing you to handle more extreme situations due to its added traction and longer foot print. The down side to having the longer track is that it will reduce the top speed of your bike on the trail by approximately 8 mph. It will also reduce the maneuverability simply because it is longer.
The LT kit really shines for cross country riding when mounted to a suitable bike. We recommend that it is used on a 500cc or larger bike.
Note: This kit uses the same length tunnel as our ST kit so it can be converted to an ST simply by purchasing a shorter track and rails.
The SX (Snow Cross) kit is a purpose built kit for snow cross racing, hard pack snow and rough terrain riding. The kit uses a hard compound 121” long Snow Hawk track that is 10.5” wide (2” narrower than our ST and LT kits) with 2-1/4” tall paddles in the center of the track and contoured down to 1″ on the outer edge paddles (meaning the track is rounded like a tire). This works extremely well on firmer snow condition such as trail and track. Along with the narrower and stiffer track, the sub frame and tunnel is also narrower for a more slim fit on the bike (the tunnel on the SX is about the same width as the bike frame). The drive axle on the SX is 1.5” higher and 1” farther forward in the tunnel than our ST and LT kits. We were able to do this on the SX kit because of the added space we gained for your feet from it being 2” narrower.
The SX kit is dual suspended; it includes the same track suspension as the ST and LT models along with an additional shock in the Sub Frame/Swing Arm. This adds up to a total of 20” of rear suspension travel.
Here’s how it works: The secondary suspension pivots from the stock swing arm location. It’s operated from a strut rod that replaces the stock motorcycle shock and attaches to a linkage arm that pivots to activate the shock mounted horizontally on the snow bike sub frame at a 4:1 ratio. This linkage suspension is fine tuned to work in conjunction with the rear skid suspension. All this adds up to a precision feeling suspension that is very tunable for racing and abusive rough terrain.
