Easykart UK Official Gearing Chart

EasyKart races are run with a set sprocket. EasyKart UK has “The EasyKart STIG!” who with the correct weights, tests and evaluates each circuit before the sprocket is set.

This is done to stop high RPM being achieved by engines and consequently reduces engine wear which results in avoiding costly rebuilds.

The EasyKart engine rpm is normally set so that the max revs met are between 15,000 and 15800 rpm. By limiting the rpm the engine performance is still impressive and helps achieve the EasyKartengine service schedule times.

In EasyKart Junior / Senior the front engine sprocket never changes and is always 11t, this must always be the original Iame sprocket.

The rear sprockets
for EasyKart race tracks are:

Track	Lights	Heavy	Junior	Chain Length
Clay Pigeon	78	79	78	102L (102 or 104 for HW)
