Frequently asked
What tire size does a Aprilia RS 125 GP Replica use?
GarageDex's powersports data shows the Aprilia RS 125 GP Replica runs a 100/80-17 front tire and a 140/70-ZR17 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like 100/80-17 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 Aprilia RS 125 GP Replica tire sizes change by year?
Yes - fitment differs across the years we cover: 2023 runs 100/80-17 front / 140/70-ZR17 rear; 2022 runs 100/80-R17 front / 140/70-ZR17 rear; 2020-2021 runs 100/80-R17 front / 130/70-R17 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.
