Hmm,Ive fitted a carbon front guard to my 999 but I did'nt have to remove the front wheel.The standard guard will come out with a bit of jiggling (word of the day!
).The carbon guard was a lot thinner and slipped behind the forks a treat.
If you need to remove the front wheel,just unbolt the calipers then undo the spindle nut.Loosen off the fork bottom pinch bolts and the spindle should "push" out.It is not threaded into the fork legs.
