The stock tire on my S2R was a 120/70 so it should be fine. A 70 is taller than a 60 by 10% of 120mm. So, if the 2003 800 came stock with the 120/60, you might have a clearance problem with the front fender. Measure the distance from the top of the tire to the bottom of the fender, if it's more than 12mm, you should be fine...chadM800 said:Will a 120/70-ZR17 fit my 2003 Monster 800.
I have a stock 120/60-VR17. Please let me know.
