with the bike sitting like that (with the YAMAHA emblem on the clutch housing sitting straight), I dropped the ninja forks down to that level so i could measure the wheelbase. the st xt660r is 1505, and the xtx is 1490.
with the ninja forks its 1470, so pretty close.
Im not sure about the rake/trail/offset yet as its just a thought at the moment.
Overseas I have a zx250 balius front end and rims that i will probably fit to it as it has a good front end with a big single disc that may be lighter for this application.

I previously had it rigged up to an xt250. bearings are all in order but forks may be a little thin. this is how it looked:



what do u guys think?
I reckon i could even use the rear rim on the xt660r as well!
Since the ninja triples slotted in so well with same sized bearings maybe the balius ones will be the same as well. ?
