KX Fork Conversion Questions

[QUOTE="KDX200Kev, post: 931289, member: 46686"] Thanks for the responses. I will measure the before and after rake/trail measurements to understand the change. Preliminary calculations puts the rake at plus 1 degree and 0.8 inches increase in trail. This is considering the 1 inch increase in lenght (35 to 36 inches) of the KX fork. Given that the KX bottom triple clamp is 6 or 7mm thinner then the KDX's and the forks can be raised 10 mm in the top triple clamp the overall lenght will increase 0.5 inches. Thus, this will result in the KDX rake increasing approximately from 26.5 to 27 degree and the trail from 4.3 to 4. 7 inches. It is possible the trail might be slightly more since the location for the axle connection may be set back farther then on the KDX. However the offset of the triple crown may be less then the KDX resulting in reduction of the rake. The KX triple clamp offset was reduced by icreasing it from 22mm to 25mm for 2003 model year. I don't know how this compares to the KDX yet but it may make a difference. As far as rate and trail goes I don't think the change will make the bike dangerous to ride. Consider that the KX 500 has a rake of 27 degree's and trail 4.6 inches and the new 2006 KX250F has a rake of 27.5 degrees and a trail of 4.7 inches. The KX swap rake/trail change is still in the ball park at least compared to MX bikes. Thus for desert riding it will be a good thing. Now if I find some good woods riding, which I wood like to do then I will bring the rake back by shorten the dog bones. Not sure of the lenght I should use but I am guessing 110 mm compared to the stock 112.5 mm ones. I have come to the conclusion I will need a 2003 hub since the rotor is different then the 2002 model and I have the KX 2003 brake calipers. As far as the shim and KDX stem transfer thats all been described well in other posts. Now if only the postman would deliver my forks. :ugg: [/QUOTE]
