Sled Requirements
Stock Sleds
Stock classes are intended for sleds that retain OEM components within the limits allowed by current RMSHA and ISR rules. Any modifications must fall within the official Stock guidelines; significant changes to engine, chassis, or suspension may move the sled into Improved or Mod.
Improved Stock Sleds
Improved Stock classes allow selected performance and durability upgrades while maintaining the overall character of the original sled. Modified components must comply with RMSHA Improved rules. Major engine or chassis alterations beyond those rules will be considered Mod.
Mod Sleds
Mod classes are for highly modified, competition-focused sleds. Engine, intake, exhaust, suspension, and chassis modifications are broadly permitted within RMSHA and ISR safety and displacement limits. All Mod sleds must still pass full safety and tech inspection.
Tech Inspection Checklist
- Functional tether that immediately kills the engine when disconnected.
- Working brakes and responsive throttle with safe return.
- Approved mudflap installed and in good condition.
- Traction devices (studs, screws, or similar) that meet Snow Devils rules for length, quantity, and placement.
- Number plates that are clearly visible to timing and course officials.
- Overall sled condition free of leaks, structural damage, or unsafe repairs.
- Final legality and class placement are determined by Snow Devils tech and safety staff.

- ISR-approved full-face helmet in good condition.
- TekVest or equivalent upper-body impact protection.
- Goggles or equivalent eye protection.
- Gloves, boots, and race-appropriate outerwear suitable for conditions.
- Any additional protective gear required by ISR or Snow Devils for the year’s event.
Pit & Staging Rules
- Obey pit speed limits at all times; no aggressive riding in the pits or staging areas.
- Only credentialed racers and crew are allowed in designated pit zones.
- Follow the directions of staging and starting-line officials without delay.
- No alcohol or impairing substances in the pits, staging, or on-course at any time.
On-Course Conduct

- If forward progress is lost, racers must safely angle the sled to avoid a downhill runaway.
