Frequently asked
What tire size does a Honda CB125e use?
GarageDex's powersports data shows the Honda CB125e runs a 80/100-18 front tire and a 90/90-18 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like 80/100-18 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 Honda CB125e tire sizes change by year?
Yes - fitment differs across the years we cover: 2023 runs 80/100-18 front / 90/90-18 rear; 2022 runs 90/100-18 front / 90/90-18 rear; 2020 runs 80/90-18 front / 90/90-18 rear; 2016 runs 80/100-18 front / 90/90-18 rear; 2014 runs 80/100-18 front / 90/90-18 rear; 2013 runs 80/100-18 front / 100/90-18 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.
