Good luck with that one Russell - they make Unicorn horns look common.
I understand that KTM wheels fit with a bit of 'fettling'.
If you ensure that the axle size is correct to start with (KTM do 2 different sizes depending on age) then it is just a matter of changing the brake rotor for the correct size and machining the disc side spacer to fit (approx 2.5mm)
I haven't done it myself, but there is quite a bit of info about it on t'internet.
That one tickled me! Its the sort of think I ask for, but if you dont ask etc. Adam, Noath Engineering, will knock up spacers, if you give him the dims. Always does a lovely job.
