I know tyres are a personal choice and depend on what you are using the bike for, I’m just wondering does the RR ‘12 prefer a certain brand? I’ve always went for Pirelli tyres for my style of riding which is fast road and track. I’ve used Supercorsas which were great for warm dry conditions and recently tried Corsa 3 which were good but you could feel less grip on track. I ride from March to October and do as many long day trips as I can and do Knockhill as often as I can. Living in Scotland limits you to dry days but has many fast flowing roads to make up for it!
