I have a 1992 GSX750F (standard OEM wheels fitted)and need to replace the tyres.
The OEM recommended tyre sizes are 110/80 R17 front, 150/70 R17. However there seems to b a very limited choice of 110/80 R17 front tyres available.
The closest alternative sizes available are 110/70 or 120/70, both of which reduce the tyre circumference (the 120/70 by the least amount). Would it be possible to fit the wider 120/70 to the existing rim? Which of these sizes would be the best alternative? Is a change in tyre size something I would need to inform my insurance company of?
Grateful for any advice.
