Sorry guys , don't have numbers for you but I do know the 15 450 forks work well on std k5 , so I had a bit of spare time today , not really but I had a 13 450 sitting there doing nothing , so swap forks , wheel and brake on std k5 and went down the back were my track is , condition were dry as I didnt worry about watering my track as I wanted to see if this set up would wash out , that was good , next was to hit a 5th gear straight with sharp bumps on it , no dramas , so this set works , these modern forks make the bike stay up in the stroke better and absorb the bumps better to , both set of forks seem to make the bike turn better to , I would jump at the 15 set up as them forks have more scope for tuning , the only thing with my stock k5 it needs new seat foam as it feels like a lounge seat and the handlebars are a tad high , but I used to the newer kxs , it does make the rear shock feel pretty ordinary , but with some improved parts , right spring ,gold valve may be a newer shock it would be a huge advantage . Next weekend I hope to be testing my son new 16 kx450 , cant wait.
