After lots of measuring and searching out dimensions etc I have calculated that the mods to the steering (SRX400 Triple clamps & FZR250 38mm forks) give me a trail of 104mm which I found out this morning is the same as the SRX400. The original SRX250 has a trail of 93mm. I am not sure on what the trail would be on the SRX250 3WP as I dont have that info but... as the lower triple is the same for both 51Y and 3WP the calculated trail would be 100mm using the same front tyre I will have on. Standard tyre size is 90/80-17 where mine will be 100/80-17 for the 3WP. So hopefully the bike will still be nippy in terms of handling which is what these little things are know for. I just need to sort out handlebars for it.. I might look at cutting of the locating tab on the FZR ones and re-welding it in the correct position... I suppose I should check out the material first lol.
