ISR Motorcycle Brake Calipers

Precision machined from a solid billet of aluminium alloy - these ultra-light and beautiful calipers are THE must-have upgrade for all front radial brake equipped bikes.

These are the first and still the best aftermarket 6 piston monoblock radial calipers for the standard 108mm radial mounting arrangement - for all current Japanese sports bikes - meaning your investment is protected because you would normally be able to simply switch them to your next bike in the future.

And, at only 718g inc. pads per caliper, you can save a massive 0.6Kg unsprung weight from your front suspension when compared with Brembo's M4 monobloc caliper - which are still only a conventional four-piston design.

• Ultra-light (0.6Kg per pair lighter than Brembo M4 monobloc 4-piston and lighter still compared with standard/OE two-piece units)
• Most common "universal" 108mm radial fork bottom bolt mount pitch
• Durable clear anodised finish
• Tufram coated aluminium alloy pistons
• Six individual pads (included) for more precise braking feel and better modulation
• Very quick and easy to bleed
• Mounting bolts and spacers can be supplied separately if required

AVAILABLE NOW FOR:

- Yamaha YZF-R1 07-08 and 09> onwards
- Yamaha VMX1700 VMAX 08> onwards
- Yamaha MT-01 07> onwards

Special direct fit calipers designed for the larger 130mm mounting pitch on these three Yamaha bikes' fork bottoms which completely avoid the need for unsightly adaptor brackets.

Size-for-size - due to their six individual pads design - they have a larger piston to pad ratio than a four piston caliper to deliver an unmatched braking power to weight ratio combined with more controllable braking due to their excellent lever feel.

- Ultra-light & durable with clear anodised finish
- Tufram coated aluminium alloy pistons
- High-performance Brake Pads included
- Mounting bolts and spacers can be supplied separately if required
