The difference between winning and losing is a very fine line...

On every mile of every race track the importance of high performance precision braking control has been proven. Total feel and response give you the confidence you need on the road. The difference between an average driver and a great driver is those who can control speed and those who cannot. Speed is nothing without control and it's a very fine line - Which is why HEL Performance only supply very fine lines.

 

Description

We are proud to introduce our latest product offering – Full CNC Machined Master Cylinders.

We manufacture all metal parts of the master cylinder (including levers) in-house on our suite of Brother and Star CNC machines from solid billets of 6082-T6 aluminium.

Each master cylinder body takes an hour of machining time to remove the material to our exacting standards with the bore measured automatically in cycle.

Each master cylinder is individually finished and assembled by hand and comes with our latest design of lever which allows three ratios from one lever.

The lever features a pill shaped hole into which one of two plugs are inserted, One has an offset hole – with the hole nearest the master cylinder you get a -1 ratio. If you rotate the plug 180 degrees it offers you a +1 ratio and if you use the plug with a central hole you obtain a 1:1 ratio. This means that with a 16mm master cylinder you can obtain a 15/16, 16/16 and 17/16 from one lever and two inserts.

With the 19mm master cyilinder you can obtain an 18/19, 19/19 and a 20/19 from one lever and two inserts.

Lever Ratios
16 – Clutch master cylinders or single front brake (smaller CC models)
18 – More lever travel and 'feel' on twin caliper systems (larger CC models)
19 – Average lever travel but harder feel – a good all rounder
20 – Less lever travel and the 'hardest feel' on the lever

 

HEL Performance Master Cylinders include a fully cnc black lever offering three ratios in one. 

 

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. 

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. The NEW caliper 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 optmised for prolonged on-limit use.
