Re: Why is there a new crank for the RB20?
thanks, i knew i was getting something mixed up. at least i was right about the conrod length!

1) Rod length has nothing to do with cc capacity
2) Stroke (58, 60, 62 etc) will change cc capacity

Re: Why is there a new crank for the RB20?
Different conrod - 116mm (same as the TV175).
I think in order to bring the cc's up to 200, it uses a 65mm bore + longer conrod to make it about 198cc's? Someone correct me if I'm wrong?
