Ride Eng. split triple clamps have been designed with four goals in mind: 1) Optimize body position: Bar position 2mm back from stock center position for a better rider triangle. Ride Eng. also offers optional offset bases for our bar mounts providing 4 bar positions as measured from the stem hole: 6mm forward, 9mm forward, 15mm forward & 18mm forward (stock positions are 3mm, 11mm, 17mm, 25mm). 2) Flex: This new split design is made from 2024 aluminum and provides far better comfort and uncompromising suspension action. 3) Improve the handling with a new gull wing design; 4) Top clamp has flex pockets and that lowers vibration with 4 polyurethane cones. Usually compatible with aftermarket stabilizers, call the manufacturer to confirm. Kit includes top clamp, bottom clamp, stem, bearing, pinch bolts, polyurethane cones & all hardware to attach the bar mount. NOTE: KT-BBM00-CA rubber mounted Bar Mount required. 20.5mm offstet reecommended for 250/300 2 stroke off-road models (20mm stock offset) & all Beta 4 stroke models (22mm stock offset).
