125cc Twins: Fournales are high pressure air shocks which do not have springs like coilover shocks. The Air Twins have 50mm diameter high pressure air filled dampers. These have a black top cover and chrome sliding tube. All Air Twins have an exposed air valve for adjusting the internal pressure. Adjusting the internal air pressure allows for changing the effective "spring strength" easily. These come with a 2 year warranty.
