This popular trial bike will be a staple off road bike for years to come.

The new 125F is new in every way, a revised frame, EFI, and all the styling cues from the bigger CRF's, we at Yoshimura wanted to do the same. We started by adding our go-to CRF muffler profile RS-9T to not only provide performance, but to provide the look of the Honda HRC factory race team. Power is up substantially with our full system in addition, this system is part of our Enduro Series line which includes an installed spark arrester. That means it's 100% ready to go on trails in all 50 states.

Benefits for the CRF125F Yoshimura RS-9T system include:

  • Significant power gains with the RS-9T full system
  • Made to look like the big brother CRF's with the RS-9T muffler
  • Stock exhaust weight: 4.6 lbs VS Yoshimura RS-9T full system weight: 4.0 lbs
  • Stainless steel header and tail-pipe
  • Repack Kits, optional Inserts and Spark Arresters are available for all models

Serious fun for the small bore. Proudly made in the USA!

Took this out on some rocky trails and the mid-range torque definitely feels stronger now. The stainless muffler looks great and hasn't shown any discoloration after a few muddy rides.

Sophia ★★★★★

Wanted a little more bark from my 125F, and this full system delivered exactly that. The stainless steel construction seems quality, and the muffler is surprisingly lightweight without being flimsy. Fit onto the revised frame was perfect, no rattling even through the whoops.

Emma ★★★★★

Fired up my 2020 CRF125F with this full stainless system and the weight savings over the stock pipe are immediately noticeable on the trails. The stainless muffler has held up great through mud and creek crossings without any rust spotting. Fitment on the revised frame was spot on, no wrestling with
