I just pivot my fork legs round
But then I have got blade forks and a non-captive mudguard!!
Serious answer
Re-use them
Before I got the blade forks I did 5-6 track days -removing and refitting the calipers every time after fitting track tyres
Also an average of a set of tyres per year
All with the same bolts without thread lock
They are not massively torqued anyway and as they are quite large bolts they are unlikely to suffer from stretch
My guess is Honda write that so that in the unlikely event they would have a leg to stand on
But don't forget that Winnebago have had to specifically put in their user manual "do not go into the back and make a drink while driving" after some twot in America put it in cruise control and did that and successfully sued them coz it didn't say not to!!!!!!!!!!!!!
