The 2020 Ski-Doo snowmobile lineup got off to an early start when the 2021 Ski-Doo Summit 850 E-TEC Turbo was released in January. That sled featured the industry’s first ever turbocharged two-stroke engine, which should be a boon to mountain riders as they can retain full horsepower even at altitude. How big is that? How about a 40-horsepower advantage over naturally aspirated engines at 8000 feet and higher. Read all about that sled and engine here.

But the 2021 Ski-Doo lineup has a lot more to offer, including some innovative new suspension designs and a brand new 600cc mill that spells the end of carbureted engines from Ski-Doo.

rMotion X Rear Suspension

rMotion X Rear Suspension

Ski-Doo’s rMotion rear suspension has long been an industry benchmark for performance. New for 2021 is the rMotion X rear suspension, which bump absorption to a new level.

The big news is the rMotion X features a whopping five-pound weight reduction, which results in less unsprung mass for a more compliant ride. Another feature is a revised geometry that has the benefit of a longer rear shock with an extra inch of suspension travel.

Here is how Ski-Doo describes the geometry changes:

“The front arm of the rMotion X rear suspension is what mates the back and front together, and creates perfect harmony over the chassis dynamics of the entire sled. By extending the length of the front arm, engineers reduced the angle that forces are transferred into the chassis, creating the ideal weight transfer back and forth.”

RAS X Front Suspension

Ski-Doo also offers a new RAS X front suspension, which was developed in conjunction with the rMotion X. It features new A-arms that bring the ski stance out to 43 inches. The suspension travel has also been increased by almost half an inch. According to Ski-Doo, the RAS X “tracks true through the harshest terrain and holds a line in the tightest corners with laser-like precision.”

Pilot X and Pilot TX Skis

Pilot X and Pilot TX Skis

Also new in the 2021 Ski-Doo snowmobile lineup are Pilot X and Pilot TX skis. These skis, along with the rMotion X and RAS X suspensions, have been optimized for the REV Gen4 platform for improved tracking and consistent cornering bite.

“Performance riders can charge harder knowing the ideal weight transfer will have the skis biting at exactly the right time to attack trail corners and they’ll notice the improved bite and flatter, more stable feel immediately,” Ski-Doo says in a release. “Upon exiting the apex and getting back on the gas, the optimized transfer moves rearward to take over for superior exit velocity giving riders pure corner-to-corner perfection.”

Rotax 600 EFI Engine

Rotax 600 EFI Engine

The 2021 Ski-Doo lineup also features a new engine option – the Rotax 600 EFI two-stroke engine. This engine was designed to give entry level riders a new option to go along with the REV Gen4 platform and it is based on the Rotax 600R E-TEC engine.

This new mill delivers a claimed 85 horsepower and its mated to an electronic fuel delivery system. This new engine marks the end of carbureted sleds from Ski-Doo. Other features include plasma-coated cylinders and a sophisticated engine control module that Ski-Doo says “delivers thrilling performance and smart efficiency.”
