TSO Garage Note
The ultimate trail armor for transforming the KTM 200 into a bottom-end tractor. Swapping to this heavy 18-gauge chamber beefs up low-end pull so you can lug through tight, technical singletrack with ease, while giving you peace of mind against log strikes and boulder bashes that turn stock pipes into scrap metal.
