The STX46 Street Performance Line is based on our popular STX46 DR1 shock absorber and developed for naked sports bikes and street performance bikes. It features a large 46mm main piston and an internal gas reservoir within the main body of the shock. With adjustable damping, you can change the behavior of the shock to suit your taste and even fit a hydraulic spring pre loader to change the stance of the bike. This is the perfect choice for the naked sports bike, or as well call it: Street Performance Line.
