Radial Brake & Clutch Lever Set
Fitment - Radial Aprilia motorcycles
Radial aftermarket brake and clutch lever set.
Radial master cylinders are mounted perpendicular to the bars but move the piston in a parallel direction as the lever meaning when you pull the lever the piston is moved 'backwards' towards the bar.
Non radial or axial master cylinders are mounted parallel to the bars and move the piston inside the master cylinder via a 90 degree pivot point on the lever meaning when you pull the lever, the piston is moved 'along' the bar.
The non radial set up is deemed just as capable as the radial for the road whereas the radial set up is generally more beneficial to racers and track day goers as it gives them better feel.
