Mountain Horse Models

The 2016 Mountain Horse ST is the most well liked, do-anything snow bike kit. It is equally at home on a leisurely trail ride, carving deep powder, or flying through the air.

Who should ride the ST kit?
The ST kit is perfect for most riders; it’s the jack-of-all-trades snow bike kit. It works very well with 250F 4-strokes, 250cc or 300cc 2-strokes, and big HP turbo bikes. It is extremely impressive on a deep powder day, and handles hard pack or firm snow like a champ. The Mountain Horse ST does well in conditions such as spring snow, powder snow, crusty snow, yellow snow, and so on.

The 2016 Mountain Horse LT is the undisputed king of the steeps. If you can’t handle 2nd place, or you crave those 4’ deep powder days- the LT is your steed.

Who should ride the LT kit?
The LT is for the rider who deliberately chooses to go out on those waist-deep days and loves it. It’s for the rider who likes to break trail, and who wants to know he’s riding what it takes to get back up the gnarly ravine he just came down. It’s also for the rider who lives to explore; and doesn’t want to worry about riding fast or carrying speed through a tough spot; because the LT has the float and traction to pull through. Whether you’re a fast rider, or a beginner, the LT is pure confidence on snow. Like the shorter ST, the LT works very well in many different snow conditions. It is very stable on the trail, and provides a solid feel.

While any weight rider will do well on the LT, we suggest that any riders over about 220lbs seriously consider the LT over the ST to gain added float and traction.

The LT works well on many bikes, but we recommend the LT for 450cc’s and up. The LT has also found its home on the 300cc 2-strokes with good success. Overall, the LT is the most confidence inspiring, will pull the steepest line on a hill, and is the most forgiving Mountain Horse kit on deeper days.

LT Kit $6,000 USD

Kit includes: Track system, spindle, 10” Backcountry ski, 3.3 gal. fuel can and quick release strap system. Requires a Fit Kit. See Fit Kit chart for details. *Shown with optional accessories.

The Mountain Horse Snow Cross (SX) kits began life as purpose-built race machines- but they’ve proven to be equally at home in the steep and deep as they have on the trails of the mid-west. The Mountain Horse SX kits are the most responsive and longest travel snow bike kits on the planet.

SX kits use a 2” narrower track and tunnel than the ST or LT kits, as well as race specific frame and suspension geometries.

For 2016, the SX no longer uses the 3rd shock on its frame. The SX now uses the same fit kits as the ST and LT kits, and can use either the traditional Solid Strut Fit Kit, or the new Timbersled Suspension Strut Fit Kit. This effectively lowers the price of the SX kits, and (using the TSS Fit Kit) provides a whole new level of SX suspension.

  • Uses Fixed Strut or New Timbersled Suspension Strut (TSS) Fit Kits
  • Ultra-responsive narrow 10.5” Convex 2.5 track
  • Available in 120” or 137” lengths

The TSS is a fit kit system that adapts the universally built Timbersled Mountain Horse snow bike kit to your model and brand of bike and adds a secondary suspension point to your track System. The TSS adds pivoting bushings into the swing arm location and adds a shock type strut that gives you suspension in the stock swing arm location of the bike. The TSS provides a very calibrated suspension feel that works in perfect harmony with the rear track suspension system and provides a feel that has never been accomplished on a production built snow bike system before. “The TSS is the single largest improvement that Timbersled has made to the Mountain Horse line up”.
