Here is the guy with the answers, you may have to register to see the posts and search the forum. I think the later wheel is narrower, hence why I run spacers on mine, it's 4 or 5mm, so you'd need to space your hubs IF that way round, sure it is, but to confuse things he talks of spacers on the hubs, so I am confused! Like I say it was some time ago. Here is the link, looks like he is still an active member with the same bike 2007 Repsol Finally complete

Well my eyes have gone funny so I'm done searching haha... End of the day it can be done, if the meat on the hub were an issue you'd have a problem or need a later wheel but that's not the case, they should even fit the upper yoke, but even then you can buy top and bottom yoke so again it could be done, they are longer so you can drop them through the top yoke to get the geom set the same. Offer them up and you will soon see. You could even use a later front mud gaurd. Good luck.
Just got a reply from Kyle racing, they say they dont know the spacer size, either they dont know or cant be bothered to look in to it, guess I cant blame them ! I've just ordered 2 of 5mm x 150mm x 150mm alloy plate to make my disc spacers, can't wait to get stuck in to it
Hi Martin, Lets see how there turn out, you might think they are shite, lol The good news is my new forks and 5mm alloy plates arrived today just done a quick measurement, the Yokes will take the new forks (bonus) but will have to stick 25mm out of the top yoke to acheive the same ride height. Happy days
Might be able to help with the spacers Tezza follow this link http://www.projection-components.co.uk/honda-6-bolt-various-widths-1010-p.asp
