vespa MAZZUCCHELLI k2d crank CHECK / 60mm long stroke / FMPguides - Solid PASSion /

CHECK of the BEST 60mm crankshaft currently, the most important crank factors:
1: centering
2: stump straightness
3: pressfit (if the cheeks will twist or not)
4: conrod
no perfect tools and this can be done better?
YESsss, agreed, but who gives a sh...
KISS principle: keep it simples stupid.
this is enough to detect GOOD and BAD cranks
nothing more needed.

I will fit this crank in my pinasco cases but in 57 mm version. The 57-110 ratio is better for a 125.

we do have a different opinion regarding 125cc 60mm cranks 😃
