Managed to get out yesterday on some quite tricky backroads by Loch Ness. Had enough time to try the IICE Air on both the -20 setting and the zero (bike as standard). At first I thought yeah, the bike is running great (as it generally does!) but not feeling that different. I then swapped the jumper over to the zero setting and the difference was apparent immediately. Felt really jerky and rough in comparison. Swapped it back to -20 and the whole plot just felt so much more refined. Yeah, that's it, more refined. Tackled a bit of cut up farm track and standing up I felt I had much finer control on the throttle than before, where if I opened the throttle there was a distinct feeling of the bike jerking forward and throwing me back unless I was careful. Now I feel like I've got much better fine control of the throttle. I'm a happy 1100 owner.
