I went ahead and ordered the new first gear... installed already
I paid $250 for it, and I cannot remember what the labour, oil and oil filter was. All in all, this is what the Gen4 should have been all along. I find it almost a transparent change. Th bike rolls much easier from standstill while there is no notable drop in RPM which the engine cannot handle...
Allround success for me. . . I am most happy and cannot think this is a change everybody/anybody would consider.
