Recently had a custom dyno tune and some new Pirelli Sport Demons fitted. I'm sure it is 95% in my head but the bike does feel nicely sorted, can't beat the feeling from new tyres. Tune hasn't made as big a difference as I expected, actually seems to have made the biggest difference at the top of the rev range, but maybe slightly crisper all round. Probably change a few more little odds and ends over winter, these bikes suck you into spending more money.
