Introduced in 1997 after 18 months of development work, the Kliktronic system is the result of a design partnership between Bob Sirett and Keith Holland. Both keen bikers, they have been involved in Engineering and Electrical development work; between them they have over 80 years of experience. The system was originally designed to overcome a disability problem. Bob's son Carl was paralysed in a motorcycle accident. Determined to get back on a bike, the system gave him a new found freedom which has now benefited many thousands of disabled riders who thought they would never ride again. The simple push button gearshift format makes fitting the unit fairly straightforward on virtually any machine - see the gallery page for some examples. The unit has also become very popular with the racing world. It is quicker (typically 50 milliseconds) and more consistent than a manual shift and has therefore found favour amongst racing and track day riders - the system is also particularly well suited to bike engined cars.
