Karting Technical Information
Each formula has a limit on engine speed, with the top category – KF1 – restricted to a maximum of 16,000rpm, considerably lower than the speeds of up to 20,000rpm that were achieved in Formula A. Engine reliability is improved under the new formula, meaning fewer mechanical retirements in the races and a reduction in costs for competitors thanks to the need for fewer engine changes.
Engines in all three formulas now have centrifugal clutches and electronic starters, eliminating the need for ‘bump starts.’ Drivers and their teams have a choice of around a dozen homologated engines and many more kart chassis with which to prepare their kart, and the regulations for each are now set in three year periods, meaning fewer changes and lower costs.
Other changes see a new compound for the control Dunlop tyre in KF1
while the hand operated brakes on the front wheels are carried into KF1 and KF2, although KF3 retains conventional rear-wheel only pedal braking.
