Throttle Body 420889030 by Can-Am

Genuine Can-Am Throttle Body — OEM Part #420889030

Breathe easy with a genuine Can-Am Throttle Body. Designed for the Defender HD11 or Traxter HD11, it fits the original airbox, ducts and clamps for a tight seal and the airflow your engine was calibrated for.

The intake path, from inlet to airbox to throttle body, has to stay sealed. One cracked boot or warped lid can let in enough dust to wear out an engine fast. This part is confirmed for 14 Can-Am models from 2026. See the full fitment list below.
