also contributes to the XCR’ s rough-trail capability. The sled tracks remarkably straight through moguls, and on normal trail conditions it feels composed and confidence-inspiring.
Compared with the Indy VR1, the XCR transfers a little more weight, resulting in some additional ski lift when you get hard on the throttle. It’ s not excessive, and the sled remains easy to turn, but it gives the XCR a playful personality. Instead of trying to keep the chassis completely neutral, it lets the rider use weight transfer as part of the experience.
There is a limit, however, and it became apparent when the trail got extremely rough. In the harshest terrain, the rear suspension could bottom out more readily than expected, even with the rear tightened all the way. During aggressive suspension cycling, the sled occasionally moved laterally rather than tracking perfectly straight. Compared with the 650 XCR we tested, the 9R didn’ t feel quite as planted in the most severe chop.
On smoother and moderately rough trails, however, the XCR is outstanding. The corner exit is one of its strongest traits. You don’ t have to roll onto the throttle cautiously. The sled almost begs you to hold it wide open as you leave a corner, and it stays remarkably flat and controlled.
The engine is unquestionably the star of the show. There is a reason Polaris is expanding the 9R’ s availability across its lineup. Its combination of displacement and naturally aspirated response makes it one of the most entertaining engines in a flatland trail sled.
At the same time, it isn’ t the strongest high-speed engine in this comparison. The 9R feels phenomenal through the first part of the speed range, but it doesn’ t have the same legs as the turbocharged Ski-Doo once speeds increase. That’ s the trade-off. The Polaris gives you immediate, usable power without the complexity or power characteristics of forced induction, but riders who spend their time looking for higher speeds will find the Ski-Doo has more to offer.
The Matryx chassis remains one of Polaris’ strongest assets. It feels natural almost immediately, with a comfortable riding position and excellent freedom of movement. The toe holds provide good support, and the rider can transition between seated and standing positions without fighting the chassis.
There are still some details we’ d like Polaris to address. The footwells could use an update, and some aspects of fit and finish— including plastic alignment, fasteners, and the way the seat attaches— don’ t quite match the premium feel of the rest of the sled. The display is also beginning to show its age compared with the newer systems from competitors, and the familiar“ camel hump” remains both an aesthetic and functional complaint.
The 9R XCR is a sled that you can grow into, though. A newer rider may find its aggressive nature demanding, but an experienced rider will appreciate the enormous performance envelope. You aren’ t likely to outgrow the engine, and the chassis gives you the ability to exploit that performance as your riding improves.
For Polaris, putting the 9R into the XCR package was a logical move. The result is an aggressive, playful, and extremely capable trail sled that combines one of Polaris’ most exciting engines with one of its most aggressive chassis.
WHAT KIND OF POWER?
All three of these sleds deliver what high-performance trail riders are looking for, but they approach the mission from different directions.
The Arctic Cat ZR 858 R-XC is the most playful and versatile of the three. Its punchy 858 engine delivers excellent bottom-end grunt, while the Catalyst chassis and EPS make it exceptionally good at attacking corners. It’ s the sled we’ d point toward a rough, technical trail when the goal is to have fun rather than simply go fast.
The Ski-Doo MXZ X-RS Competition 850 Turbo R is the speed specialist. Its smooth, linear turbo power is almost absurdly strong yet remarkably manageable. The suspension gives it the composure to handle rough terrain, but this is ultimately the sled for riders who want the throttle to keep working long after the other machines have run out of steam.
The Polaris 9R XCR 137 occupies an appealing middle ground. Its big, naturally aspirated engine delivers immediate torque and fantastic acceleration, while the chassis provides a fun yet aggressive ride that skilled riders can take advantage of and new riders can still utilize. It combines enormous performance with a broad capability range.
And that’ s the real takeaway from this comparison. There is no shortage of horsepower here. What separates these sleds is how they deliver that power and how the chassis allows the rider to use it. For the hair-on-fire rider who wants to go fast, all three are legitimate weapons. The Arctic Cat wants to corner, the Ski-Doo wants to run, and the Polaris wants to do a little bit of everything while reminding you that there really is no replacement for displacement. Pick your poison.
