Option 4 Dave, buy yourself a Honda RS250 GP bike, the 600's wont get away from you on the straights then, i have one which i take to trackdays along with my MC21 with a few HRC bits bolted on, one's around 60bhp, and the others around 80bhp, but guess which one comes out the van most, yep the 60bhp one, more easier to ride and more fun, knowing youv'e just annoyed a load of 600's with only 60bhp.
