Radial master cylinder
At last a radial master cylinder from ISR! The advantage over the already excellent ISR master cylinders is that the radial lever is more efficient, giving even more power and feel. It also has fingertip control to allow adjustment for reach and ratio whilst riding. The two piece design makes lever replacement a 20 second change. The remote master cylinder design also has the benefit of being interchangeable for brake or clutch use permitting matching levers. Click here to see a disassembled lever.

There is no standard reach lever available.
This lever is available in both Integral and remote reservoir designs.

Available with 15mm or 17.5mm bore.

Weight: 440g
Handlebar size: 22mm

Adjustable reach lever £250.00 (including VAT)

Please remember

If you are moving from an integral to remote master cylinder, you will need a brake fluid remote reservoir.

We can supply parts to repair or rebuild the master cylinders if, for example, the seals are damaged or the lever is broken. See rebuild kits for details.

Also, if you replace the master cylinder and intend to use the bike on the road, you will need some form of Banjo brake light switch. See braking accessories for details.

When changing your master cylinder we recommend that you upgrade to a quality brake line to get the best out of the increased braking performance. It also wouldn't do any harm to replace the brake fluid, because higher performance brakes need higher performance brake fluid to get the best out of the system.
