Yoshimura RS-12 Exhaust System | Track Tested



Yoshimura R&D

The 2021 Yamaha YZ450F is easily one of our favorite bikes of the year; thanks to its excellent motor, plush suspension, and overall feel on the track. However, the power delivery can be too aggressive at times and many seem to share this same opinion. We reached out to our friends at Yoshimura and got our hands on their all-new RS-12 system to see if we could smoothen out that aggressive hit on the YZ450F. After bolting up the exhaust, SML test rider Pat Foster spun a few laps before giving us his thoughts on the Yoshimura exhaust.
