Hi everyone, I have just brought a GSX600F 1991 model, Both tyres have had it so I need to buy some new ones. According to the manual my tyres are 110/80/17 front, 140/80/17 rear. (which is the same as it has on it) Could I put on different sizes as these are hard to get hold off and really exspensive? I know there is probably a limit to the width of the tyre to clear everything but does the height of the tyre matter that much? If I put a 110/70/17 front & 140/70/17 rear what difference would it make to the handling? I can't find much on the net as it seems this bike changed its wheel sizes around 1995. Does anyone have a list of what would fit on my bike? Thanks Ant
