Enginecasing: p80

(Art.-no. 10030000)

or crank racing maz normall

NO racer only touring, ride on town.

Happy Xmass!

Concerning cylinder kits add DR kits into the list of options cause I have heard those are quite tractable kits, good for touring

I think DR177 its no good for my conception.
DR 177 its too weak to me.
I have more power.
