Personally only recently having changed from 600 to 1000 on the track. I'm really struggling with the change. Seems like the bike wants to be ridden really differently. I'm still kinda trying to ride it like the R6 and its just so hard to actually get to full throttle out of corners as you spend so much more time cranked over. I end up getting smoked by everyone driving out of corners while on the R6 I used to gain time on those around me out of corners. It is getting very frustrating but with more track time I'm hoping to modify my riding to suit what I believe the bike wants. At the creek im now only about 1s under my times on my R6. Even though I've gone from a relatively stock R6 (slip on, aftermarket rear shock, revalved stock front cartridges) to a Full ASC specced ZX10r (25mm Ohlins cartridges, Ohlins ttx36 rear shock etc). Although I suspect there is still a fair amount of set up to be done on my new bike!
