Snowmobiles have considerably evolved since they were first invented. Joseph-Armand Bombardier himself would be overwhelmed by all the progress made, especially over the last decade. Tracks, handlebars, suspensions, skis and engines; every component has been revisited to improve riding dynamics and comfort.


Without question, the most significant evolution in recent years is the riding position. Up until the late 1990s, most snowmobiles basically offered the same traditional riding position. These winter dinosaurs were kind of like cruiser motorcycles with skis and tracks; the rider had his or her legs and arms almost fully extended. Such riding position was little ergonomic and did not encourage sporty riding over long stretches of winding, bumpy trails.

Revolution in ergonomics
In 2003, world-renowned manufacturer BRP, through its Ski-Doo division, took the entire industry by storm with the introduction of the all-new REV chassis. This revolutionary platform delivered a huge blow to the competition by offering a whole new riding position that proved more ergonomic in every respect. The rider was now sitting closer to the front, allowing for enhanced control and comfort on any type of trails.

Like most rivals, American manufacturer Arctic Cat had to strike back. Following several months of intense work and development, they finally came up with the new and innovative Twin Spar chassis, much to the delight of the brand's enthusiasts. This ultra-modern platform moves the rider 20 to 30 centimeters forward. As a result, the rider's weight is more centralized, which improves handling, control and comfort. In addition, the Twin Spar uses Arctic Cat's "Infinite Rider Positioning" system. The seat, handlebar and adjustable footrests allow you to easily find the perfect riding position. The raised seat allows a more natural knee bend for enhanced comfort over long rides.

Not one but two
Meanwhile, at Yamaha, engineers have been understandably looking to make things very different. The Deltabox II architecture (second generation) offers a more relaxed riding position -- sort of a mix between the traditional riding position and the one afforded by most new chassis. In doing so, Yamaha wants to keep the focus on overall ergonomics while maintaining the center of gravity low enough to avoid compromising stability in corners.
