Patriot 9R RMK® SPS 155

Description

Meet the 2027 Polaris Patriot 9R RMK® SPS 155, a mountain sled that looks ready to pick a line before you even throw a leg over it. Dressed in , it has that clean, can’t-miss presence on the snow—bold without trying too hard, and perfectly at home parked at the trailhead or pointed straight at the steep stuff. (And if you’re the type who likes options, this model also comes in Gloss Black and INDY® Red / White Lightning / Gloss Black.)

At the heart of this RMK is the Patriot 9R—a liquid-cooled, 2-cylinder, 2-stroke built to feel lively and responsive when the terrain gets serious. It’s a horizontal in-line setup with reed valve breathing, fuel injection, and gas / oil injected fueling that runs on regular fuel. With 899 cc of displacement, it brings that big-bore authority that mountain riders crave—snappy when you want it, steady when you need it, and always eager to keep the momentum going.

Power delivery is handled through a continuously variable (CVT) system with belt drive and a P-22 / TEAM LWT clutch package—built for the kind of quick transitions mountain riding demands, whether you’re rolling into a sidehill or popping up and over a wind lip. A thumb throttle keeps control simple and natural, and when the day turns into a tight maneuvering session, reverse is there to save energy (and dignity). Starting is classic and dependable with a pull starter—simple, light, and ready when you are.

This sled is built on Polaris’ MATRYX aluminum frame, keeping things strong and purposeful without feeling bulky. At 126.7 inches long and 43.4 inches wide, it strikes a balance between stability and the nimble feel you want when you’re threading through trees or setting an edge on a slope. The adjustable ski stance—36 to 38 inches—lets you tune the front end to match your style and the day’s conditions.

Up front, the RMK® React™ independent A-arm suspension delivers 9 inches of travel, paired with WER® Velocity adjustable gas shocks with remote reservoirs (coil-over), so you can dial things in without drama. Out back, the RMK® KHAOS® rear suspension offers a big 16 inches of travel, supported by two rear WER® Velocity remote-reservoir shocks plus a matching center WER® Velocity unit—again, fully adjustable gas shocks with remote reservoirs. The result is a ride that can stay composed when things get choppy, but still feels playful when you’re picking your way through technical terrain.

The business end is a Series 8 track—155 inches long, 15 inches wide, with a towering 2.75-inch lug height—made to grab snow and keep driving when the climb gets real. Up front, Gripper® skis (plastic) and carbide skags help the sled track with confidence, while a manual ProTaper™ handlebar setup keeps steering direct and connected—exactly what you want when the mountain starts asking questions.

It’s also thoughtfully set up for real riding days: an 11-gallon fuel capacity for long laps, a hydraulic disc rear brake from RMK® for consistent control, and practical protections like a belt guard and snow guard. The one-piece vinyl seat keeps the layout simple and rider-focused (it’s a true 1-seat machine), while the low, tinted LED lighting adds a sharp look and useful visibility when the day runs late. You’ll also get a fuel level gauge and a temperature warning light, plus adjustable heated grips to keep your hands happy when winter decides to remind you who’s in charge.

In , this Patriot 9R RMK® SPS 155 doesn’t just show up—it announces itself, then heads straight for the kind of terrain that makes ordinary sleds turn back.
