That's been my dilemma for a while now. I have a ZX6R track bike, and whilst it's a great bike, every time I ride my 899 on the road, I can't but think the 899 would make a much better track bike, but at the same time, it's a bit too valuable and nice to use as a track bike I'm taking it to the Ducati day at Silverstone, which will be it's first outing on track, so I might have my mind made up for me then
