Thermal Insulation 705801623 by Can-Am

Genuine Can-Am Thermal Insulation — OEM Part #705801623

Keep heat and noise where they belong with a genuine Can-Am Thermal Insulation. Built for the Defender HD11 or Traxter HD11, it bolts to the original mounts so the exhaust stays sealed, quiet and clear of plastics, wiring and riders.

The exhaust routes hot gas away from the engine, controls noise and keeps heat away from panels, wiring and riders. Loose shields and leaks lead to melted parts and failed inspections. This part is confirmed for 7 Can-Am models from 2026. See the full fitment list below.
