I've done it! I have a 2019 cb500x front wheel and fork lowers on my 750x. it rides fantastic and has a nice light feel. I have gained a lot of influence in steering with pegs as well. I had been running a mitas e07 120/90/17 which worked great for trails and some hardcore stuff but the extra mass and width was very noticeable.
For those interested I have taken some measurements of the fork parts:
For those paying attention, the NC has a longer damper rod than the CBX despite the fact that honda CLAIMS the CBX has 1/2" more travel. I am not sure where they got that math but as far as I was able to see and measure it had just under 5.5" of travel. I was able to combine the NC fork tube and the CBX lowers with a 1" spacer under the damping rod to get a longer overall fork. Someday I will have a longer damping rod made.
as for the wheel fitment and spacing, it fits great with the extra length in suspension however, the NC fork spacing is 10mm wider than the CBX. this means with the standard CBX spacers in the wheel is 5mm off-center. Proper spacers and a longer axle are being machined but the 5mm offset does not make it ride too wonky.
COST!!!!! I'm sure everybody would love to know the dollariedoos spent on this shenanigans sooo here it is:
used wheel/tire $300
used forks $180 each
new OE axle, spacers, bolts $50
new brake rotor and hardware $160
new fork oil $20?
so like $900
honestly it could be done by buying OE cb500x fork lowers which go for $96 on partzilla but I also got adjustable spring preload caps from the CBX forks.
let me know what you think!
