Specifically developed for the Suzuki RM85, this BOYESEN impeller is aimed at motocross riders concerned about engine cooling. Designed to fit into the original water pump housing, it aims to improve fluid circulation and thermal management during intense track sessions.

• Optimizes water flow for more consistent heat exchange and better engine temperature control.
• Reduces hydraulic losses at the impeller, limiting cooling variations at high RPM.
• Helps maintain performance during critical race phases by limiting temperature rise.

This part is intended for installation on the RM85 and is aimed at riders who push hard and want more uniform cooling without heavy modifications. Direct fit and the same dimensions as the original: please check compatibility with your year and version.
