Unmatched Fun Factor in Any Terrain
The RMK Khaos brings wild, agile performance and unmatched responsiveness for deep snow thrills.
The Best Mountain Sled Got Even Better
2025 Boost and 9R Khaos models are up to 6.5 lbs. lighter with a redesigned throttle, lower seat, improved board clean-out, and lightweight headlight.
Rider-First Design
Narrow seat, tank, and console improve rider connection, while refined seat and boards enhance mobility. The new throttle system gives you better control.
Float and Fly
The RMK Khaos rear suspension delivers traction and transfer for playful handling. Available in 146, 155, and 165 lengths.
Choose Your Power
