Brembo 19RCS Clutch Master Cylinder 25mm Bars Fold-Up Lever 110A89770 and Reservoir Kit 110A26386

Brembo 19RCS Clutch Master Cylinder 25mm Handlebar [Harley Davidson] Fold-Up Lever + Clutch 15cc Reservoir Kit 110A26386

This is the 25mm handlebar version designed for Harley Davidsons and some other makes with a 25mm Handlebar.

For Harley Davisdon Handelbars 25mm, Brembo common radial master cylinders are 19 x 18 and 19 x 20, and for Nissin is 19 x 21.
The choice between these models is due to the different feeling that each of them gives to the rider: the 19 x 18 is the extremist version, the shorter wheelbase is preferred by riders who like more power and excellent progressiveness, with a working stroke slightly shorter than the 19x20, the 19 x 20 is the "ready" version, the longer the wheelbase is, the shorter lever runs, as well less power is transferred to the piston.

Brembo 19RCS Adjustable Ratio combines in one product two aims.

Features:

• Adjustable wheelbase: 16/18 mm. for piston ø 16 and 18/20 mm. for piston ø 19
• Forged and CNC finished pump body
• Hard oxidation finish
• Articulated brake lever
• Lever distance adjustment

Brembo 19RCS Adjustable Ratio combines in one product two aims.

Adjustable ratio: RCS system
This new patented device allows to modify the pump lever ratio on two values, 18 or 20 mm, by simply rotation of the eccentric drive placed on the front of the lever drive. By the RCS system – Ratio Click System – it is very easy to pass from one configuration to the other one, modifying the lever ratio to adjust it to the different characteristics of the braking system, of the usage and driving, such as, for ex., the wet or dry conditions, asphalt with more or less grip, circuit with strong braking.
This adjustment is the element missing till now to get the ideal feeling among the rider, the driving style, the bike and the circuit.

NB. The red spot on the eccentric drive identifies position 18mm of the lever ratio, while black indicates position 20mm.
