ok im running my aerox with a polini variator and better springs but im wondering on what to do with the contra ?
so when is it necessary to fit a stronger contra, i ride a zip with a italkit alu 70 with doppler s3r exhaust, stiffer clutch springs n lighter rollers. would it b a good idea to fit a stronger contra spring n what will it do?
When you feel the need...
