Exceptional Design and Performance
The MessnerMoto Master Radial Cylinder CNC is built for café racers, track riders, street fighters, custom motorcycles, and anyone seeking exceptional performance with a broad range of adjustability.
Inspired by MotoGP engineering, this radial master cylinder aligns the piston parallel to lever pull—delivering braking force directly and efficiently while minimizing flex and improving modulation. This layout yields a sharper, more predictable feel—ideal for spirited riding, whether on the street, off-road or the track.
Versatile Design for Brake and Clutch Compatibility
Whether you’re refining a classic café racer or upgrading a modern sportbike, the MessnerMoto Master Radial Cylinder offers a stylish, high-performance solution. Its symmetrical design allows installation on either the brake or clutch side, simplifying your build and maintaining a clean, balanced appearance.
Each master cylinder is produced in limited small batches to ensure meticulous craftsmanship and consistent performance. With over 30 precision-machined components, it delivers sharp, predictable and smooth brake feel.
The internal piston is sourced from a high-quality component manufacturer, ensuring reliability and compatibility with standard service kits. Available in 16 mm and 19 mm versions.
Easy and Precise Adjustment for Custom Fit
This master cylinder features a wide range of adjustments for both lever feel and reach. Using simple, tool-free knobs, you can fine-tune the setup to match your motorcycle and riding style.
- Leverage Ratio: 2.9:1 to 6.8:1
-
Lever Distance: 38 mm to 68 mm
Thanks to the innovative design, it has a very large range of brake power adjustment.
We manufacture only 16 mm and 19 mm versions due to their superior versatility:
-
The 16 mm variant replicates the behavior of 14 mm–17.5 mm cylinders.
-
The 19 mm variant covers 17.5 mm–20 mm systems, ideal for dual-disc brake setups.
For front dual brake setups we advise 19mm version for single side fork brakes 16mm will be more the enough.
An adjustable reach handle is included as standard. Both the power range and grip distance are easily set using tactile, anti-vibration knobs—no tools required.
Includes a Matching Oil Reservoir
Each unit includes a matching oil reservoir, ensuring perfect visual and mechanical integration. Checking or refilling fluid is simple—just remove the top screw.
The reservoir angle relative to the master cylinder can be adjusted, allowing you to achieve a low-profile layout. Angling it slightly backward creates a sleeker silhouette while maintaining full function.
Free Cable-to-Hydraulic Conversion Kit
When ordering a pair of master cylinders (for brake and clutch), MessnerMoto includes a miniature cable-to-hydraulic transfer mechanism free of charge.
This mechanism lets you convert a cable-operated clutch into a hydraulic system, bringing smoother, more precise control to your motorcycle. We highly recommend this upgrade for improved reliability and lever feel.
For clutch applications, we suggest using the 16 mm master cylinder, as it pairs best with the internal 14 mm piston in our transfer mechanism.
Built to Last with Premium Materials
The MessnerMoto Master Radial Cylinder is CNC-machined from 6061-T6 aluminum. After machining, each component is polished and sandblasted to achieve a satin texture before being hard-anodized in black.
This finish is both scratch-resistant and weatherproof, ensuring durability even under the harshest riding conditions while maintaining a refined, minimalist aesthetic.

I recently installed the MessnerMoto Master Radial Cylinder on my BMW R nineT custom build, and I’m seriously impressed. The machining quality is excellent—everything fits perfectly, and the lever feel is firm yet smooth. The adjustable reach is a great touch, allowing fine-tuning for different riding positions. It completely transformed my brake and clutch feel, much more consistent and responsive than the stock setup. The black anodized finish also looks fantastic and matches the rest of my MessnerMoto parts. Installation was straightforward, and the included reservoir fits neatly on the bars. A premium product that performs as good as it looks. Highly recommended for café racer or modern custom builds.

This master cylinder is a pleasure to use. Adjustable reach, silky smooth hydraulics, and impeccable finish. Installed on my Kawasaki Z650RS—braking is noticeably sharper and more refined.

Radial cylinder is smooth, strong, and looks great. Full hand feel, great bite—no more mush. Fitted it on my CB650R, and things just feel more connected. Highly recommend for performance upgrades.

Perfect balance between firm and progressive braking. Installation on my Triumph Bonneville was straightforward, and the adjustable lever position is a huge plus. The quality machining elevates the cockpit aesthetic instantly.

I am a believer! Ngl, I was pretty skeptical about buying these. I haven’t heard of these guys before and they’re pretty expensive so I was gonna play it safe and go with a different brand.
But damn am I glad I didn’t! I got just one, in case I got scammed or was disappointed but now I wish I would’ve just got the set.
These things are like design porn. They’re quality, they’re gorgeous, and they are well designed. Definitely became a loyal customer after this one. Thx guys!

Major upgrade! The brake bite and modulation are spot-on. The radial design feels right between your fingers. No fluid creep even after spirited canyon rides. MessnerMoto nailed the balance of function and style.

Hi, I would like to purchase a master cylinder and clip-ons. Can you advise if it is possible to order them in silver as opposed to black? Many thanks.
Mirjan Čubrić –
Hi Karl,
this is exclusive small volume production. Only 40 Sets of Master Cylinder are made per batch. The price is already low for this kind of production.
It would be not economical to make silver Master Cylinder because 99% of people are buying only Black parts believe it or not, we learned that the hard way.
