i had the link and ended up taking it off.mb1 revalve and stock link was way better.ive found running the forks up in the clamps quite a bit and shortening the wheelbase has helped mine a ton and im really very happy with the way it works.i would say if you could get it for cheap and just wanted to try it to go ahead.i just bought an 07 kx 250f and cant believe how much better i like the 450.even in the corners and the weight of the 250 didnt do much for me.i feel once you find the sweet spot on these 450's there hard to beat.ive had all the 450's except the yamaha and this kawi just flat works on the track.oh ya,the 250 is for sale,maybe one hour on it, basically new bike,bought new 9-26-07,black excels,should have the title in a couple weeks.
