Öhlins develops its proprietary and innovative suspension components at the highest levels of racing from open-wheel car racing, to MotoGP, to off-road competition on two and four wheels. Oil in the damper is kept under pressure to avoid free play. Three different systems give you smooth damping in all conditions. Base damping gives 18 adjustable settings (clicks) for maximum tunability and control.
