Yamaha has brought something new to the market, introducing the new WR125R, a street legal 125 that is a great value in the small bore market and is clearly designed with the intention of having loads of fun.

Packing more performance into this liquid cooled, fuel injected, 6 speed 125cc bike is what we are here for. So our engineers rolled up their sleeves to loose some weight and create more power for this new small bore, and they delivered!

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.

This RS-2 Race Series system is proudly engineered, developed, and built in Chino, CA.—Yoshimura quality you can count on.
