The snowmobile season has started a bit earlier for me this year compared to last. I’ve just received the snowmobile I’ll be testing this winter: the 2025 Ski-Doo MXZ X-RS. I’m thrilled because I had the chance to try the Renegade X-RS in 2023 when the REV Gen5 platform was introduced. I also briefly tested the MXZ X-RS in 2024. That Renegade was essentially identical to the MXZ I’ll have this winter, and I really enjoyed it. Throughout this article, you’ll notice some changes made to the MXZ for 2025, as well as my expectations for the upcoming season.
REV Gen5 Chassis and 850 E-TEC Engine: A Winning Combination
The REV Gen5 chassis is now in its third year. From its launch, it represented a significant improvement over the previous generation. First, the side panels are narrower. Second, the snowmobile is quieter and vibrates noticeably less than before. To achieve this, Ski-Doo added a fourth engine mount and improved insulation, all while enhancing the cooling of engine components and handling. Thanks to these vibration and cooling improvements, Ski-Doo estimates that the drive belt will have a longer lifespan.
The 2025 MXZ I’m testing is equipped with the 165 hp 850 E-TEC engine. Those who purchase the X-RS model can also opt for the 600R E-TEC engine. Or perhaps you’re one of the lucky ones who managed to get their hands on the 850 E-TEC Turbo R version of the competition model! The 850 E-TEC engine in my MXZ X-RS 2025 has been paired for a few years with a CVT transmission featuring a pDrive primary clutch and a QRS Vent secondary clutch.
Semi-Active Smart-Shox Suspension: Enhanced Comfort and Precision
My MXZ X-RS 2025 features a semi-active Smart-Shox suspension system. Sensors take real-time readings of the trail and throttle position, adjusting the shock compression and rebound accordingly. The automatic calibration is based on the selected driving mode, with three options available.
ICE Ripper XT Track: Improved Grip and Safety
For my MXZ X-RS 2025, I chose the studded ICE Ripper XT 137 × 15 × 1.5 track. Note that a 129-inch track is also available. At the rear, the rMotion X suspension is paired with a high-performance Brembo four-piston brake and an adjustable brake lever. The front ski stance is 43 inches, and the snowmobile is equipped with premium LED headlights. With a dry weight of 506 lbs, the MXZ X-RS 2025 is 4 lbs lighter than its direct competitor, the Polaris INDY VR1 with active Dynamix suspension.
New for 2025
For 2025, two major updates have been introduced for the MXZ X-RS. First, Ski-Doo has integrated a GPS function into the 10.25-inch display, which is the case for my test snowmobile. This means you no longer need to connect your phone to the dashboard to access GPS features—great news! This display will also now be available as an option on MXZ models with the 600R E-TEC engine. Additionally, almost the entire MXZ lineup (excluding the SPORTS version) gets a brand-new front suspension. Ski-Doo has integrated the RAS RX suspension and the new Pilot RX skis into these models.
According to Ski-Doo, these new suspension updates should give sporty riders a greater sense of confidence. Improved handling and precision are promised. The new suspension geometry claims to reduce roll by 20%, and the skis should stay more firmly planted on the ground. The new Pilot RX skis promise exceptional precision.
The skis on the MXZ X-RS 2025 have also been redesigned. They should offer better grip on hard surfaces and in softer snow.
Performance of the 2025 Ski-Doo MXZ X-RS: Expectations and Outlook
I have high expectations for my MXZ X-RS 2025 this season. First, considering this is the third year of this chassis for Ski-Doo, I expect excellent overall performance. Most components have already been thoroughly tested over the past few winters. The combination of the 850 cc engine and its CVT transmission should deliver outstanding performance and reliability, not to mention the refined vibration and noise levels. In terms of performance, with the studded track, I expect superb acceleration and responsiveness in all trail conditions. As for the Smart-Shox suspension, I anticipate excellent handling, especially on bumpy trails, regardless of the driving mode.
That said, I do have some reservations. The behaviour of the new front suspension leaves me a bit skeptical. In the past, I felt this was a weak point for Ski-Doo compared to some competitors. I think the updates for the 2025 model should improve the snowmobile’s overall trail performance. I’m eager to see if I can tackle corners with greater ease. But most importantly, I’m looking forward to seeing if the suspension meets my expectations.
Finally, I might have the opportunity to test a Polaris trail snowmobile with the new semi-active Dynamix suspension. If so, I’ll likely be able to make a fair comparison with the suspension of my MXZ X-RS 2025. You’ll be able to read all about it in my upcoming articles following my test of this snowmobile.
A big thank you to SledMagazine.com and Ski-Doo for allowing me to conduct these tests for several years now!
