Introducing the 2011 Polaris RMK® - the lightest, most durable RMK ever built. Purpose-built for riders tired of trail sleds with long tunnels. Designed aggressively lighter but built structurally stronger in all the right places - weight reduced only where weight doesn't matter. Centralized mass for precise control and an easier ride. RMK Coil-Over Rear Suspension for better bump control and nimble balance. We made it light, we made it simple, we made it work - so you can ride harder, longer, and ride again tomorrow. We set out to build the best RMK ever - the end result was 431 lbs. of Rocky Mountain Terrain Domination.
