Standard Mountain Horse Technical Specs
The First Ever Snow Bike Kit Designed for the Mountains (Patent Pending)

Riding a Mountain Horse snow bike provides the same enjoyment as snowmobiling but with its own unique characteristics. A bike and a sled can go similar places in the mountains but the bike can take a completely different route. Simply put, a snow bike can go places a sled cannot. A sled can go straight up a hill better than a snow bike because of the horsepower they have, but then they have to come straight back down due to their lack of maneuverability. Sleds are much heavier and have a planted ski stance making them hard to side hill and perform off camber turns, requiring a lot of strength and experience to do this.

Snow bikes are about 200 pounds lighter than a sled. When riding a snow bike you balance it upright the same as you would on any bike, but when you stop it sticks in the snow and holds itself up without having to put your foot down. The track and ski are more stable on the snow than the tires are on the dirt, so you are able to travel across the side of hill as if it were flat ground without worrying about the bike slipping out from under you. When you climb a long steep hill you don’t need to go straight up and down several times to make it to the top like you would on a sled. You just take off side hilling and zigzag your way to the top with ease and confidence. You can also stop on the side of a hill, have a look around and then take off again without getting stuck. It is much easier to go where you want on a snow bike; its handling is much more accurate and will fit through tight areas like between trees and across narrow snow bridges.
A snow bike also has much more control going down hills than a sled. You don’t need to go straight down with the possibility of getting out of control. If it is too steep or has too many obstructing trees to go straight down, you can side hill and do switch backs similar to what you do on snow skis or a snow board. With this technique you are able to stop in the middle of a steep hill if you choose to.
This amount of control will give you the confidence to safely go and explore areas that you always dreamed of going. On a snow bike you don’t have to stay on trails like when riding dirt bikes. Snow biking gives you the freedom to fly through the trees, up and down mountains, across powdery meadows, through ravines and ditches, across creeks, or find fresh tracks no matter how torn up your normal riding area is.

Specifications:
  • Uses Timbersled’s lightweight snowmobile style Mtn. Tamer Back Suspension System
  • System drives off the front of the track and has a 20° approach angle to the snow
  • Uses a Camoplast Challenger Track (121” long, 12 ¼” wide, 1 ¾” deep lug)
  • Uses a spindle adapter and Simmons dual keel flexi ski in place of the front wheel and tire
  • System adds 60 lbs. to the bike. Total weight of a fully fueled 450cc dirt bike = 300 lbs.
Sub-Frame & Tunnel Assembly:

The backbone of the assembly is a uniquely designed tubular sub-frame that is very strong and lightweight. The tunnel is a 3 piece assembly that bolts to the sub-frame. It has all the mounting points for the back suspension and drive system. The tunnel assembly also provides protection for your feet and gives a good spot to bolt on accessories, such as gas can and cargo bags.

The sub-frame and tunnel assembly bolt on to the bike using the factory swing arm pin and are supported with a solid aluminum strut-rod that mounts in place of the factory back shock. The assembly bolts in tight and does not move up and down like the stock motorcycle back suspension.

Mtn. Tamer Back Suspension System:

The Mtn. Tamer suspension system does not use a traditional mono shock design that a dirt bike uses. This system has a front and back shock and is designed to put even pressure on the ground between the front and back portion of the track and is also able to automatically adjust independently from the front to back portions of the track on uneven terrain such as bumps, jumps and dips. This provides a super smooth ride and best possible traction in deep snow.

  • Uses our same unique lightweight design suspension that Timbersled uses on snowmobiles
  • Provides an extremely smooth ride with 13” of vertical travel
  • Fully adjustable for all types of abusive riding such as deep powder or jumping
  • 20° track approach angle to the snow provides the ultimate deep snow flotation
Front Spindle & Ski Mount:

The Spindle is a heavy-duty welded aluminum adapter that replaces the tire. It mounts on a Simmons dual keel flexi ski. This ski has proven to be the most stable ski for this application. When riding in any snow condition the ski will not wash out from under you even on a steep the hill side or when making a tight turn. This gives you a more stable feeling than the tire on dirt.

Drive System:

Here is how it works, 1st Drive chain from motor to jack shaft. 2nd Jack shaft transfers to outside of tunnel. 3rd Secondary chain drives from jack-shaft to drive shaft, 4th The system drives off the front of the track.

  • Uses a disc brake with Wilwood caliper
  • Chain tensioners on both drive chains provides adjustment for different gearing options
  • Secondary chain drive system is inside a sealed chain case
  • The drive system uses: O-ring chains, 4140 Chrome-Moly steel axles, CNC machined sprockets and bearing cages, over-sized sealed axle bearing

Warning

The Mountain Horse snow bike has the ability to put you in harm’s way. Always be aware of avalanche and mountain terrain dangers. We strongly recommend you take a course on avalanche safety, carry the proper equipment and check the reports before you head out.
