Slip forks and wheel in and rode it , just as that guy who won the 2 stroke race thing in usa , sean colliers , than mxa magazine tested it, our forks were fully gold valve as well , they were off my sons 15 450 , sadly they had to go on the 15 bike , as it up for sale to be replaced by a 16 , I did not worry about measurements , std k5 triple clamps , whole 15 front brake as well , one day I will switch to this front end when they become more available , at the moment I saw a set for 1k , to much for me , I wait and get a roller with a stuffed engine . We tested this set up at my own track against the 01 framed k5 to see how it went , the front showed no signs of washing out , held its line well and stayed up in the stroke better , impressed.
