The billet aluminium Pretech caliper is a high quality piece of engineering designed and manufactured in England. The design incorporates a strengthening brace at the mid point of the caliper that stops caliper flex under braking. Caliper flex can reduce the pressure applied under heavy braking and increase stopping distances. This engineering feature isn't incorporated in all six pot calipers and the ability of the Pretech to brake heavily without flex is one reason why racers use Pretech calipers.
Twin Power worked with Pretech to re-design the orignal Thruxton fitting caliper to now work for the Bonnie, T100, Scrambler, America and 2011-> Speedmaster. This quality kit from Twin Power comes complete with EBC brake pads installed with copper grease, all stainless fittings, four fitting shims and the bleed nipple thread wrapped with PTFE tape to ensure quick and easy bleeding of the fluid.
This caliper in conjunction with the OEM master cylinder has excellent stopping performance and gives the brake lever a real nice progressive feel that the OEM caliper can't match. If you need a good looking caliper with life saving performance, the Pretech will be one of your favourite upgrades. The Pretech caliper is available in many colours.
N.B. If used with the Bonneville or T100 braced mudguard, the bottom left hand brace needs to be persuaded out by 13mm (1/2") to clear the new caliper. This is very easy to accomplish.**Black calipers are kept in stock, coloured or polished calipers are made to order and take an extra 14-16 days **Installation Instructions
