ISR - Radial Master Cylinder



Fully Adjustable Radial Master Cylinder from ISR - Sweden.

The advantage over conventionally configured master cylinders is that the ISR radial master cylinder is more efficient, giving increased power and better braking feel. It also has fingertip control to allow adjustment for both reach and lever ratio, no tools needed. It can even be adjusted while riding the bike. The two piece design makes lever replacement a 20 second operation. The remote master cylinder design also has the benefit of being interchangeable for brake or clutch use permitting matching lever.

Adjustable lever ratio
The range of adjustment is 5:1 to 3.8:1. In layman’s terms this means that when set to the minimum (3.8:1) you have to move the lever further to get the same braking effect but there is a lot more sensitivity in the feel of the brakes.

Reach adjustable
Carried out by hexagonal adjuster on the lever; moving the adjuster clockwise lowers the ratio and anticlockwise increases it. There are no positve stops allowing any ratio between the extremes to be selected, giving maximum adjustment capability. Total adjustable range of 28mm. Adjustment can be easily carried out while riding using the index finger, without the need to let go of the handlebar or throttle.

Modular construction
It is constructed using different "modules", allowing for various parts to be swapped after crash damage without having to swap/bleed the entire system.

Interchangeable for brake or clutch use
The design also has the unique benefit of being able to be configured for brake or clutch use (permitting matching levers and reduced spares requirements for race teams). This is achieved by the quickly detachable lever pivot mechanism being separate from the cylinder, meaning it can be rotated and switched between clutch and brake operation quickly and easily. Alternatively, a complete matching Cable Clutch Lever Assembly is available - see below under related products.

Additional Benefits
  • Available with either integral or remote reservoir designs (if you do not already have a remote reservoir you will need to fit one along with reservoir pipe and pipe clips).
  • Available with 15mm or 17.5mm bore.
  • Integral nipple for rapid bleeding after assembly/servicing.
  • Clear anodised, corrosion resistant finish.
  • Weight 440g.
  • Handlebar size 22mm.

All ISR master cylinders use a standard banjo bolt fitment for brakes lines of M10 x 1.25mm. Single or double brake line banjo bolts are available either for road use which has a brake light switch in the head or a standard bolt for racing. Banjo bolt fitment is parallel to the handlebar.
