Developed in New Zealand the Sharp Shifter pneumatic air shifter came about as a result of an industrial accident - with reduced strength in one hand a solution to gear changes at high speed was required to ensure maximum safety for the driver during kart racing.

The prototype product was raced for two seasons at the Hamilton Kart Club in New Zealand, thereafter a production model was built, and subsequently launched at the 2001 World Karting Show in Chicago.

Since then the Sharp Shifter has been enthusiastically received by racers world wide.

Sharp Shifter Legal for SKUSA and World Kart Association Racing

Super Karts USA (SKUSA) National Technical Adviser, John R. Clasen, has confirmed that Sharp Shifter meets the racing regulations for both 250 and Sprint 125 divisions. SKUSA rule 20.3.4.15.7 relating to gearbox shifting allows for mechanical gearbox shifting only and the absence of an ignition kill device fulfils this requirement.

He says, “Provided there is no ignition kill device it is legal for the Sprint 125 division, and for the 250 division it is legal either way.”

The Sharp Shifter kart air shifter also meets the requirements of the World Kart Association which states in rule 613.9 that air shifters are allowed for 80cc and 125cc MOTO.

 

Sharp Shifter is manufactured in Hamilton New Zealand and exported throughout the world
