Solid Billet CNC Machined

Many calipers on the market today are forged to hit a lower price point. This limits design as threads and internal flow circuit need to be machine detailed afterwards. HEL calipers are precision machined entirely from race grade solid billet 6082-T6 aluminium - maximising weight and minimising material used. Machined and forged calipers are NOT comparable, so be sure to insist on machined for the very best design, precision construction and finish on the market.

Our V2 model is a progression from our original 100mm, 108mm and 130mm calipers. These new versions feature new styling which allowed us to offer an outboard bleed nipple and banjo take off meaning bleeding and installation are easier. They also feature five bolts rather than the previous three to offer more stability under braking and strength through the caliper. They come complete with stainless steel pad pins which have been upgraded (not in photo) to offer both an r clip at the back and lockwire hole at the front. They still take the original pad design we have always used meaning you can choose the manufacturer and compound you prefer. Fully CNC machined at our HQ in Exeter – they are a huge step forward.

Complete Circuit Technology

Unlike some calipers which only feed from one side, HEL calipers utilise complete circuit technology. This race inspired feature allows fluid to fully circulate the caliper meaning easier and faster removal of air from the system when bleeding.

Heat Sink Pistons

HEL's stainless pistons act as a heat sink drawing the extreme temperatures generated when racing down into the piston - and away from the caliper body where the fluid circulates. This keeps the fluid at optimum operating temperature and away from boiling point (which varies depending on fluid specification). On track and on the limit the performance advantage is simply stunning, allowing fade-free powerful braking and ultra consistent feel - lap after lap after lap.

World Class Research & Development

The HEL brake lab develops all braking products directly from a huge resource of track data collected from HEL's Superbike and Road Racing teams. We have had so much great feedback on just how good our V1 calipers were that we decided to look at the styling and the performance again to make them even better. The V2 design is based around very extreme race loading values taken from worst-case scenario calculations - the maximum amount of front brake force possible before the bike would start rotating around the front wheel and actually flip.

Structural integrity, stiffness and displacement resistance are all fully optimised for prolonged on-limit use.
