The tyres are what it came with, the Contis Sport Attacks. My first bike had K3s which I must admit felt alot stickier, but they were virtually shedding rubber before my eyes. The Contis aren't bad though I've managed to scrub them to the edges without any drama and 800miles in they have hardly worn. I have big plans for that garage. There's a big pile of skirting to one side. When its gone it means the house is finished and I've got space for a second bike again. Should take only about another 5 years.
