Frequently asked
What tire size does a ATK GT650R use?
GarageDex's powersports data shows the ATK GT650R runs a 120/60-ZR17 front tire and a 160/60-ZR17 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like 120/60-ZR17 reads as tread width (mm) / aspect ratio (% of width) - rim diameter (in). Match all three so the tire fits the rim and clears the swingarm and fender.
Do the ATK GT650R tire sizes change by year?
Yes - fitment differs across the years we cover: 2015-2016 runs 120/60-ZR17 front / 160/60-ZR17 rear; 2014 runs 120/60-ZR16 front / 160/60-ZR16 rear; 2012 runs 120/80-16 front / 170/80-15 rear. Match your exact year in the table.
Can I fit a different tire size?
Stick to the stock size - it's matched to the rim width, speedometer, and handling. A wider tire can rub the swingarm or fender and throws off the speedo, so only deviate on a shop's advice.
