Dirt bikes have nimble handling, plush suspension and limited power. For 2016 the Timbersled Team focused on adding that nimble dirt bike feel, maximizing power transfer to the snow, and on designing a rear suspension that not only had a perfect travel path, but was so ultra-sensitive to terrain and snow consistency changes that it could rise on top of the snow like no other snow bike conversion system ever conceived.
Chasing efficiency is not just accomplished by going light-weight. It comes through perfecting a suspension’s compression path to eliminate parasitic loss from track tensioning changes, by significantly reducing rotating mass, by enhancing response at the moment of inertia, and by questioning everything. We have made more significant improvements for 2016 to the Mountain Horse lineup than we’ve made in all previous years combined.
Nothing beats the best technology, combined with the most experience. That’s one reason why nothing beats the 2016 Timbersled Mountain Horse.
In previous years the LT kit (137″ long track) used the same tunnel as the ST kit (120″ long track). New for 2015 the LT kit now has its own longer tipped up powder tunnel that places the bumper and grab handle right where you need it. The LT also offers a unique look all its own, and the new longer tunnel prevents the track from throwing powder forward toward the rider.
Looks aren’t the only changes. Our objectives with the 2015 LT were to have it handle and ride better on the trail than previous years’ ST kits, to lower seat height, and to take deep powder and hill climbing performance to entirely new levels. We completely annihilated all our objectives. Without a doubt, the 2015 LT kit is the powder shredding king, and it’s no slouch on the trail. If you’re the type of rider that doesn’t want to worry about how deep, how steep, or how ridiculous the terrain is; the 2015 Mountain Horse LT is the easy choice.
The SX, or Snow Cross kit has been our test-bed for new technology, performance and durability; and we’ve put all we’ve learned from the SX into our 2015 ST and LT kits. Because we’ve achieved such high performance levels and almost SX like suspension and handling traits with the 2015 ST kit; the 2015 SX will remain limited in production, with only 50 available. The SX will not receive all the upgrades of the 2015 ST/LT’s, but will feature the following changes:
Convex Pivoting Rear Suspension
Bottomless Rail System
Convex 2.5 Track
Dominator Drive System
New HD Fork Clamp system
New Strut Rod Lower Bolt
New Chain Case Cover Material
The SX uses the Mountain Addiction utility jug with slide rail mounting system, aluminum chain case cover, chassis angles and its ride height remains unchanged.

If you have ridden a snow bike in the mountains you know that you have to carry extra gas if you want to insure that you make it back to the truck. The ST and LT kits now come with a Mountain Addiction Gas-Can that is a perfect fit in our newly designed gas-rack that is incorporated into the tunnel. The Can simply drops in the rack and is held in place with a high quality ratcheting strap that is similar to what is used on a snowboard binding. The system is extremely simple to use making your fill-ups quicker and reduces the risk of losing your can in the back country. Note: This does not apply to the SX model (gas can not included on SX).
We’ve designed new graphics to compliment the aggressive new performance levels we’ve achieved for 2015. During Snow Check, you’ll be able to select our standard (shown) or colored graphics to match the brand or decal colors of your motorcycle. Your Mountain Horse has never looked so good.
The rear suspension on the 2015 ST and LT kits has been refined and mounted higher in the tunnel to create a lower ride height. The chassis has also been re-engineered to sit at a 4 degree flatter angle putting less weight on the ski, and biasing more weight to the track. This creates more traction, more controlled steering and significantly improves ride quality. It also allowed us to re-design the suspension rails, refine the bump stops, and recalibrate the rear suspension. Incredibly, we were also able to add 12% more available rear suspension travel over previous ST/LT models, all while lowering the seat height. Note: The 2015 ST and LT kits use the same Fit Kits as the 2014 and older kits do.
The Tunnel top and sides have been completely re-engineered. To accommodate the lower ride height changes, a kick up in the back of the tunnel was added that regains track clearance, puts the grab handle in a more convenient location and brings a new more aggressive look to the Mountain Horse. The side panels have been thoroughly tested and meticulously refined for added strength (both torsional and yield point), structural rigidity, and weight as the primary emphasis.
The front edges of the tunnel have been trimmed back to let the track paddles absorb impact and clear snow better. This yields better floatation and movement through the snow, helps deflect damaging objects, and provides more clearance for the heels of your boots. Also, because the new kit is so much more rigid, the Mtn. Tamer rear suspension works even better, and gets on top of the powder like never before.
The 2015 ST and LT kits come equipped with our new rigid 4 bolt bearing housings and more efficient double row bearings. The engineered rigidity and structure of the new 4 bolt housings combined with other key drive train, side panel, tunnel, chain case cover and frame enhancements to produce a chassis that puts more power to the track and is designed to provide many years of trouble-free service. This structural synergy also keeps the axles in alignment which should provide years of bearing life and rider confidence- especially for those with high horsepower or turbo bikes.
Note: Timbersled will be selling an update kit for all previous year Mountain Horse kits on our Replacement Parts Page.
The drive axle on the 2015 kits has been rolled forward and up to create higher drive axle ground clearance and to tuck the track farther up under the bike. We have also installed smaller diameter drive wheels to add even more clearance. These changes yield better deep snow performance because the drive wheels are now higher above the snow allowing the bike to have better flotation. The chain tensioner has also been carefully analyzed, tested, and simplified into a stronger single bolt adjuster; making it easier to maintain proper chain tension. The tensioner sprocket location and role have also been re-engineered; and thoroughly tested and proven on both stock and turbo bikes. The drive axle bolts now have fold-over locking tabs that securely lock them in place preventing them from coming loose. This eliminates the need to check tightness of the bolts.
The 2015 chain case cover is made from a high impact Nylo-fiber plastic and bolts around the perimeter with 6 bolts. Internally, the cover is designed with a reinforced impact zone around the outer perimeter to make it extremely impact resistant. The new shape of the cover rounds into the tunnel side with no square point. This makes it slither through the snow much smoother and deflect hard objects like rocks and stumps.
The brake system has been refined to create more clearance between the track and brake disc. With the added clearance, the disc picks up less snow from the track creating more positive stopping power. Also the brake caliper is mounted lower in the frame creating less snow build up around the brake system.
As you may already know, the suspension on the Mountain Horse is not snow bike technology, but comes from Timbersled’s line of aftermarket snowmobile products. The system is called the Mtn. Tamer Rear Suspension System and is truly the reason the Mountain Horse performs so well. Over the past 4 years, we have refined the system for the snow bike application with smoother Fox shocks and an articulating front suspension arm that allows you to easily lean on the trail. For 2015 we have modified the front arc of the rails for a flatter track angle that will improve how the bike gets on top of the snow providing better deep snow floatation.
The Timbersled Backcountry ski has been a work in progress since it came out 2 years ago. We have redesigned the outer ski skags to provide more secure handling while cornering on hard-packed trails. You can now lean into a corner on the trail and drive through it without the feeling that you need to hang your leg out for balance. The ski simply does not grab ruts and can hold a line on even the hardest trail conditions.
Note: These new skags can be purchased and installed on any previous year Timbersled Backcountry ski.
