What would you recommend for my MC21 NSR 250 tyres for track use only? I've had a look on "Jake Wilson" for 110/70 x 17", and 150/60 x 17" tyres and can only find mixed brand pairs. Can I get a set slicks that will fit?? I've finally sold my faithful Gixxer750, and the NSR will now be my main track weapon. Cheers, Al.
