Description


In order to achieve higher speeds, one should reach for the racing shaft. The extended intake timing results in a much freer engine revs. This measure is especially noticeable with high-revving cylinders.

The quality of the crankshafts is very good and so they resist even highest revs. Especially for the higher capacity engines from 125ccm up they are an optimal supplement to extend the usable speed range of racing cylinders without spitback in the lower speed range.

The PK XL2, ETS 125 shaft also offers the enormous advantage that it has the most stable cone and can therefore cope with much higher forces. In addition, it allows the use of ultra-light pole wheels, with which a better acceleration behaviour can be achieved.

Für den Preis unschlagbar. Rundlauf kleiner 2/100. Auf dem langen Drehschieber Einlasszeiten etwa 205°. Perfekt für potente Drehschieber-Motoren. Dank 24er Konus hält auch alles!

Geschicktes Teil für Tuner fahrs sie auch im O-Motor und der Roller läuft besser.
