Yoshimura RS-2 Stainless Full Exhaust with Aluminum Muffler - Yamaha WR125R 2026

Part# 131250C350

We enlisted our RS-2 off-road muffler to create power for the small bore engine and boy did it!

Lighter than stock exhaust by over 4 lbs., while smoothing out the powerband and adding up to 14.7% more hp @7800 rpm and up to 13.3% more torque @7,800 rpm. Now this little 125 can get up and go! This Race Series system comes with a USFS spark arrestor already installed so you can head right out to the wilderness with it.

Stock muffler: 11.3 lbs.

RS-2 full system: 7.2 lbs.
