In my research a 17" x 3.5" front and and 17" x 4.25" rear makes sense and provides a good choice of rubber. I also note some others have had lots of success with this wheel combination in Carrozzeria (not available anymore). I am leaning towards Kineo wheels for my 2004 Thruxton to reduce wheel weight although there are some issues such as speedo calibration and fitting a lower front mudguard with a 17 in front and offset with a fat rear. For these reasons I am likely to stick with OEM sizes as I like the nimble handling of the thinner wheels. If I stay 'thin' in Kineo then I am limited to Speed Demons, GT501 and perhaps BT45's in the OEM size
