137 Snowmobile Track - Traction, Flotation and Control

Introducing the 137 Snowmobile Track

Snowmobiling is a thrilling winter sport that allows riders to explore snow-covered landscapes at high speeds. Advances in snowmobile technology have led to machines that are lighter, faster, and more powerful than ever before. One important innovation in snowmobiles is the 137 track, which provides superior traction, acceleration, and maneuverability on the snow.

What is a 137 Snowmobile Track?

The number 137 refers to the length of the snowmobile track measured in inches. A 137 inch track means the track is 11 feet and 5 inches long. This length provides the optimal balance of flotation on snow along with maneuverability and weight.

Longer tracks like the 137 inch design have more surface area in contact with the snow, allowing for better floatation and less sinking on deep, powdery snow. Shorter tracks may sink more in deep snow conditions. The extended length also distributes the weight of the snowmobile and rider over a larger area, reducing the pressure on the snow to avoid sinking.

Benefits of the 137 Track

There are several key benefits riders can expect from choosing a snowmobile with a 137 track:

• Traction - The long track length provides excellent traction, even in loose snow. More track on snow means more grip when accelerating and turning.
• Flotation - As mentioned, the long 137 track disperses the weight over more space to prevent sinking in deep powder.
• Ride Quality - The elongated track softens the ride by absorbing bumps and vibrations when riding over uneven terrain.
• Acceleration - The 137 track is optimized for rapid acceleration and responsive handling.
• Maneuverability - Despite the long length, the 137 track retains a nimble, easy turning feel.

137 Track Design and Technology

Modern 137 tracks feature innovative designs to enhance performance:

• Lug Profile - The lug height, shape, and pattern greatly impact traction. Deep, angled lugs provide bite in loose snow.
• Track Flex - Some tracks are designed to flex and conform to terrain for better flotation over uneven snow surfaces.
• Rails - Built-in rails on the track help guide it straight and minimize sideways slip when accelerating.
• Paddles - Large paddle-like lugs on the rear help propel and steer the snowmobile.

Manufacturers also use tough, flexible materials for optimal durability and shock absorption. Rubber, carbon fiber, and Kevlar are common track materials.

137 Track Snowmobiles

Many top snowmobile brands offer 137 track lengths in their lineup. Two popular models include:

Ski-Doo Summit X 137

The Ski-Doo Summit X uses the renowned 137 inch PowderMax FlexEdge track designed for deep snow flotation and traction. It excels at climbing steep, powdery slopes thanks to its extreme maneuverability.

Polaris RMK 137

Polaris RMK snowmobiles with 137 Pro Ride tracks are favorites for boondocking in remote snowy terrain. The track length combined with the Pro Ride rear suspension soaks up big bumps and provides a plush ride.

Riding Techniques for 137 Track Snowmobiles

While 137 tracks enhance performance in many ways, they also handle somewhat differently than shorter tracked sleds. Here are some riding techniques to get the most from your 137 inch snowmobile:

1. Lean into Turns

The longer track wants to stay flat on its edge when cornering. Lean your body downhill into the turn to help roll the sled over on edge and carve a tighter arc.

2. Manage Momentum

A 137 track has momentum when moving that may take some getting used to. Allow yourself more room to slow down and take turns wider until you become familiar with the sled.

3. Hammer the Throttle

On steep ascents, apply quick bursts of acceleration to keep momentum and minimize sinking or slipping backwards. The abundant power from big engines provides tons of climbing traction.

4. Ride Light

Sit lightly in the saddle and be prepared to shift your weight and stance as needed over varied terrain. Absorb sharp bumps with your knees and elbows.

5. Pick Lines Carefully

Look ahead on climbs and descents to pick the best line avoiding obstacles. Subtle weight shifts can help steer around hazards when riding aggressively.

Get Ready to Ride!

With its unmatched powder prowess, the 137 inch track length continues to be popular on mountain snowmobiles. Choosing a sled equipped with a 137 track opens up a world of deep snow adventure and backcountry riding challenges. With practice, you’ll soon be carving fresh lines through the powder like a pro! Just be sure to respect the machine’s capabilities and ease into controlling the sled at speed in the snow.

FAQs

Why is 137 inches the ideal snowmobile track length?

The 137 inch length provides the best balance of traction, acceleration, weight, flotation and maneuverability for a snowmobile track. Longer tracks can get too heavy, while shorter ones may sacrifice performance in deep snow.

What is the difference between a 137 track and 155 track?

A 155 inch track is longer by 18 inches, which improves deep powder flotation but makes the sled heavier and a bit harder to maneuver. The shorter 137 track is more agile while still floating well over snow.

How does lug height affect snowmobile track performance?

Taller lugs improve traction and grip in loose or deep snow conditions. However, lug height needs to be balanced with maintaining good trail grip and minimizing vibration.

Should I upgrade to a 137 inch track?

If you regularly ride in deep powder and boondocking terrain, a 137 track upgrade can significantly enhance your snowmobile's capabilities. Just be prepared for the different handling compared to shorter tracks.

What maintenance does a 137 track require?

Check track tension and alignment periodically. Lubricate to prevent premature wear. Inspect for cuts, missing lugs or other damage. Replace when worn or damaged.
