DescriptionThe whole story▼
When every metre of braking distance counts, the Brembo PR19x18 Racing XR01171 delivers the kind of precise, linear feel that MotoGP and Superbike riders depend on. CNC-machined from high-grade aluminium and finished to MotoGP specification, this radial master cylinder gives professional racers and serious track-day riders unrivalled control and confidence under the most extreme braking loads.
Key Features
- CNC-machined aluminium body for exceptional dimensional accuracy and structural rigidity under race loads
- Hard-anodised surface finish to MotoGP standard — maximises durability and corrosion resistance over a full racing season
- 19 mm piston diameter paired with an 18 mm lever ratio delivers progressive, linear braking force and outstanding modulation
- Folding lever as standard — reduces the risk of lever breakage and handlebar damage in the event of a fall
- Compatible with an optional remote adjuster, allowing micrometric lever-reach adjustment on the move — essential for professional racing setups
- Hydraulic brake light switch port available for circuit use where required
Built for the Track
The PR19x18 is derived directly from Brembo's racing programme and carries no compromises associated with road-legal products. The 19 mm bore and 18 mm lever ratio combination is a well-proven specification in top-level competition, producing a firm, direct pedal feel that inspires confidence whether you are trail-braking into a hairpin or scrubbing speed from race pace on a long straight. The hard-anodised housing resists the heat cycles, fluid exposure and mechanical stress that a season of racing will inevitably impose.
Remote Adjuster Compatibility
A remote adjuster can be retrofitted to allow the rider to fine-tune lever reach to the nearest fraction of a millimetre while on circuit — a feature that professional teams and fast amateur racers use to match brake feel to tyre temperature and fuel load as a session progresses. Note that special adapters are required for installation and are not included in the scope of delivery.
