The 249cc air cooled EFI engine produces a nice base for adding good power to this great trail bike. We developed a stainless system with our updated RS-2 muffler and the new 250F responded nicely adding more HP and Torque through the entire power curve. 

As part of our Enduro Series line which includes an installed spark arrester, this system is 100% ready to go on trails in all 50 states.

Benefits for the CRF250F Yoshimura RS-2 system include:

• Significant power gains with the RS-2 full system
• Revised RS-2 muffler
• USFS spark arrester included and installed
