ive been really worried about shearing cranks too, especially now that ill be putting some power through them this next year. they look pretty well built. luckily mopedshop seems to carry c2 cranks but i dunno how uptodate the site it. i've been toying with the possibility of derbi variant crankshafts if they are the same stroke. just as a backup option. they look very similar to my crank. hell after you shim it right i bet you could just run a derbi variator with it as well. whats the v2 crank look like??? any pictures? tapered?
derbi/minarelli stroke differences?
