I just rode both back to back last night (both in Green). The 23 seems less sensitive for the first maybe 1/4 or 1/3 throttle turn, then the power ramps up at the end. This makes throttle control easier when you are going slow, tight turns, etc. I have a 22, I don't think the throttle is "too sensitive", but I would say the 23 seemed a little easier to regulate throttle.
If I try it again, I'll try it on blue.
