SP Ventilated Caliper Racing Piston kit.

Ventilated Caliper Racing Pistons are the state of the art design and will allow the brake system to maintain a cooler and more of a  temperature stability during hard braking on the street and on the race track. Spears Racing has been on the leading edge of making new products for the little commuter style bikes for decades, most of these products come from the motorcycle being used for something other than what it was intended to be use for…RACING

Late model OEM calipers have come a long way in terms of both performance and design. Far more rigid than their predecessors, the late generation examples from Brembo, Nissin, Sumitomo, Tokico and others provide ultra stiff and relatively lightweight designs have been instrumental in bringing braking performance to new levels.

But they’re still using problematic aluminum pistons – lightweight, yes, but also highly conductive in providing a huge heat path into the hydraulic braking systems of your little commuter motorcycles. Spears Racing  is now addressing this with specially engineered ventilated stainless steel pistons of proprietary material that all but eliminates those shortcoming:

• Reducing thermal conductivity by 94%
• Dramatically improves piston retraction, reduces brake drag
• Increases top speed
• Eliminates fluid boil
• Improves release time for greater control exiting the apex
• Improves overall braking consistency under severe racing condition

Ventilated Caliper Racing Pistons are the state of the art design and are used at all levels of racing around the world .This style caliper pistons have been used for years in superbike racing
