Hill start assist retrofit IS AVAILABLE for my 2014 LC GSA and that's one of the early ones and the cost fitted £220 and a "30 minute job while you have a coffee".Dealer confirmed by checking my Reg.no. I've not booked it in yet, still pondering the benefits but I recall one heavily loaded, pillioned hill start event, when a voice in my head said 'You'd better not stall it here '. I can't however see a great need when solo.
Had hill start on my previous K1600's and fwiw - yes it's a fact that nobody needs it - but. It is very useful under certain conditions and circumstances. If you are fully loaded and have to stop on a very steep hill type junction to have a good clear look, then it's invaluable and if you're stuck in a jam for a while and on an incline it is nice to be able to relax with both feet on the ground and both hands relaxed. Small price really for occasional benefit. I'm awaiting my new GSA tb which has all the latest toys including hill start control and looking forward to having this again. Mostly ride solo so unlikely to use it often but when partner out with me nice to know it's avail if required.
