The Polini 152cc racing cylinder kit is a great torquey upgrade to the standard T5 125cc top end. Providing much more power lower down the rev range, and great off the mark.
The original cylinder head can be used with this kit, or you can upgrade to the SIP Performance Polini T5 152cc Cylinder Head.

A great plug and play kit, with modifications needed. But always remember to check your jetting.

This cylinder produces 13.7hp at 6500 rpm / 16.5NM at 4850 rpm with an otherwise standard engine and original exhaust, reaching a top speed of approx 70mph with a 22T clutch (original 20T)
