I think what Brett wants to know like all other MC21 NSR250 owners is what is the best compromise for sprockets between acceleration and speed.

Is the 14/40 'lively' setup a faster accelerating but generally slightly slower NSR setup than stock?

I am racing my NSR's in interclub in VIC, Australia and I use stock gearing everywhere at broadford, winton and philip island but I know that for some tracks like PI you need more top end speed to get a better lap time??

Is the 14/40 setup quite noticeably harder accelerating than the stock setup??
