Product description

PQ8 Quickshifter system specially developed for Harley-Davidson Milwaukee-Eight engine bikes equipped bike models, such as Street Glide, Road Glide, Electra Glide, Road King and Softtail. The quick shift is done by interrupt the fuel injectors and features adjustable kill time, shift force, smooth and compus shift function.

Cordona use strain gauge sensor technology which gives a consistent and distinct shift performance. The GP SG M8 switch is based on same technology platform we have used in Moto3 World Championship together with KTM Factory Moto3 and Honda Factory bikes.

The new M8 size sensor is a larger variant of our smaller M6 sensor.  We used both sensor sizes in WSSP and SBK world championship as well as for many street and sport applications.

The Cordona PQ8 Quickshifter is maybe the most robust ‘stand-alone’ system at the market. It has been used in Moto2 Word Championship bikes, for racing bikes, street bikes and in many categories for years. It can be used with all variants of strain gauge sensors, like rod linkage, toe PEG or sensors integrated in shift levers.
