Real gains you can feel

Stiffen rebound for crisp turn-in and high-speed confidence, then back it off for commuting comfort. Use the separate compression adjuster to tighten chassis response and reduce brake dive, especially if you run wider wheels and tyres. The result is a 1 Series that feels planted, predictable and quick to respond.

Engineered to last

Every kit is built from high quality components, endurance tested and finished in corrosion resistant stainless steel. The twin-tube layout and precision valving deliver repeatable performance in all weather conditions.
