If you've spent any time on a modern Ski-Doo lately, you've probably seen or used pilot ts skis, and honestly, they change the game when it comes to trail adjustability. For the longest time, we just accepted that if the trail conditions changed halfway through the day, we were stuck with whatever handling we had. If the crust got hard and the skis started darting, you just muscled through it. If it got soft and you lost your "bite" in the corners, you just slowed down. But the TS (Tunable Ski) system actually gives you a way to fight back without pulling out a wrench in the freezing cold.
I remember the first time I really messed around with the adjustment knob on these things. It was one of those typical mid-February mornings where the trails started out like concrete but turned into a mashed-potato mess by 2:00 PM. Normally, that's a recipe for a tiring afternoon, but being able to just reach down and dial in more or less "blade" made a world of difference.
What Makes These Skis Different?
Most snowmobile skis are static pieces of plastic with a wear bar bolted to the bottom. If you want more traction, you buy a longer carbide. If you want less steering effort, you go shorter. With pilot ts skis, the carbide isn't just a fixed bar; it's a thin, stainless steel blade that you can raise or lower using a knob located right in front of the spindle.
The range of adjustment is about half an inch. That might not sound like much when you're looking at it in the garage, but on the snow, it's massive. You can literally watch the blade go up and down as you turn the knob. There are about 20 clicks of adjustment, so you can really fine-tune the pressure depending on exactly what the trail is doing under your track.
The Ease of On-The-Fly Adjustments
The best part about this setup is that you don't need tools. We've all been there—trying to adjust suspension or ski pressure with frozen fingers, dropping a 10mm wrench into the snow, never to be seen again. With the pilot ts skis, you just hop off, turn the knob a few clicks clockwise to get more bite, or counter-clockwise to reduce steering effort. It takes maybe five seconds.
I've found that I usually start my morning with the blades tucked up a bit. When the groomers have just gone through and the trail is flat and fast, you don't need a ton of aggressive carbide. But as the day goes on and the corners get chewed up, I'll click them down a few notches to make sure the front end stays planted. It keeps the sled from pushing in the corners, which is a huge confidence booster when you're tired at the end of a 200-mile day.
Dealing With the "Darting" Issue
If you've been riding for a while, you know that "darting" is the absolute worst. It's that annoying feeling where your skis want to follow the ruts left by the person in front of you, making the sled feel twitchy and unpredictable. A lot of people think the solution is more carbide, but usually, that just makes it worse.
The pilot ts skis handle this pretty uniquely. Because the blade is so thin and the ski bottom has a specific square-keel design, it tends to track much straighter than a traditional dual-runner or a wide single-runner ski. If you start feeling that hunting sensation, you can actually back the blade off (raise it up) to let the ski float a bit more. It's a level of control that I didn't realize I was missing until I had it.
How They Compare to the Pilot 5.7
Before the TS became popular, the Pilot 5.7 was the gold standard for Ski-Doo trail riders. It's a great ski—light, simple, and predictable. However, the 5.7 is a "set it and forget it" component. If you're a rider who hits a lot of different elevations or moves between groomed trails and lake ice, the 5.7 can feel like a compromise.
The pilot ts skis are definitely heavier than the 5.7s because of the internal screw mechanism and the beefier construction. Some of the hardcore mountain guys or weight-weenies might complain about that extra pound or two, but for a trail rider, the trade-off for adjustability is well worth it. You aren't jumping these sleds off 30-foot cornices; you're looking for a smooth, predictable line through a wooded turn.
Maintenance and Keeping the Knobs Turning
I'll be the first to admit that these skis aren't perfect. Because there's a mechanical moving part sitting right where snow, ice, and salt congregate, they do require a little bit of love. I've seen guys who never touch their adjustment knobs all season, and then they wonder why the mechanism is seized up come March.
It's a good habit to turn the knobs through their full range of motion every time you wash the sled or put it away for the weekend. A little bit of moisture-displacing lubricant (like a silicone spray or a light grease) on the screw threads goes a long way. If you ride in areas where they salt the road crossings, that salt can get in there and corrode the aluminum and steel parts. Just a quick spray keeps everything clicking smoothly.
Replacing the Carbides
Eventually, you're going to hit a rock or ride over enough gravel to dull the blades. Replacing the runners on pilot ts skis is a bit different than a standard ski. You have to wind the blade all the way down to its lowest point to access the pins. It's not hard, but it's a specific process.
One thing to keep in mind is that the replacement blades are a bit more expensive than a generic set of Woody's or Stud Boy carbides. You're paying for that specialized thin-blade design. However, since you can retract them when you're loading onto a trailer or riding on a thin base, I've found that they actually last a bit longer because you aren't grinding them into the pavement as much.
Is the Upgrade Worth It?
If you're buying a new sled and looking at the options list, or if you're browsing the classifieds for a used MXZ or Renegade, you might wonder if you should specifically look for a machine with pilot ts skis.
In my opinion, if you're a 90% trail rider, the answer is a resounding yes. The ability to tune your handling to the specific snow conditions of the day makes the ride so much less fatiguing. You don't realize how much you're "fighting" your sled until you find that perfect setting where it just rails through the corners with one hand on the bars.
That said, if you spend most of your time off-trail or in deep powder, these probably aren't for you. The TS design is fairly narrow, and the adjustment mechanism adds weight that you don't want in the deep stuff. For the backcountry, you're better off with a Pilot DS-2 or DS-3. But for the high-mileage trail enthusiast, it's one of the best innovations BRP has come out with in the last decade.
Final Thoughts on the Trail
The bottom line is that pilot ts skis take the guesswork out of your suspension setup. We spend thousands of dollars on high-end shocks and clutching, yet we often ignore the only part of the sled that actually touches the snow and steers the beast.
Next time you're out on a ride and the sun starts hitting the snow, making everything a bit greasy and loose, just reach down and give those knobs a couple of clicks. It's a satisfying feeling when you hit the next corner and the sled tracks exactly where you point it. It might seem like a small detail, but on a long trip, it's the difference between ending the day with sore shoulders or ending it with a smile. Don't be afraid to experiment with the settings—that's what they're there for!
