Recently laced a "08" KX450F new rear hub to a new Excel rim and using new Excel spokes which are non-shouldered and slightly bigger. The first time I tried it some of the spokes were to short and some to long. 9 spokes were too long to be exact. At first I thought this was a problem and called the company that I had purchased the rim and spoke kit from but they didn't have a clue other than to say that I had maybe screwed up the lacing pattern. I have laced many rims and the pattern was correct. What I discovered upon closer hub inspection was that indeed the inside spokes on the brake rotor side require a slightly longer spoke (about a 1/4"). My "05" RMZ450, "07" RM250 and my son's "04" CRF250R all use the same size spokes on both sides of the hub. Friggin Kawasaki! Anyway I hope this post will help someone else someday
