Andy,
As you know ive had quite a few bikes

i prefer not to have it, never had it on 4 bikes prior to 2012, then had it on my 2012 triple black and never used it, didnt have it on my L/C GSA which ive just been to italy on, wound the preload up before i left because of the luggage, got home and rewound it.
Ive now just ordered the new 2017 TB GSA and it comes as standard otherwise i would not have bothered.
Personal choice, yes.....needed, no
Lloyd
