TSO Garage Note
The ultimate armor upgrade for turning the lightning-quick Suzuki RM250 into a tractable off-road or woods weapon. This heavy 18-gauge chamber fills out the bottom-end and lower midrange so you can hook up effortlessly in loose or technical terrain, while easily absorbing the brutal rock and log strikes that would crush a standard race pipe.
