Thats one option, you can of course pull away as normal and it should disengage itself. Does need a fair bit of revs though!
My 1200 was as you say and I used to disengage it before riding off using the dab on the front brake, but the few times I've used it during the short time I've ridden my 1250 before lockdown I didn't really notice any difference whether HH was engaged or not it's now that smooth.


No harm done as I had enough strength left to let it gently down, only damage to my pride! But I just wasn't expecting it to hold. If you have never had it then you expect the bike to behave differently. So for that reason I am going to disengage it completely.
