TSO Garage Note
The ultimate armor upgrade for bulletproofing early-2000s KTM 200 woods weapons. This heavy 18-gauge chamber beefs up bottom-end torque to give you smooth, tractable power for lugging through tight singletrack, while easily absorbing the brutal rock and tree impacts that turn stock expansion chambers into scrap metal.
