now if you get the Tuned version it has some modding done to the sleeve i believe.

there are different combinations if you look on the Novarossi website i think its the ST which has the silicon and the tuned crankshaft

the SC which has the Silicon and the Ceramic bearing

or the SCT which has the Silicon and the Ceramic and the Tuned crankshaft.

hope this helps
