Frequently asked
What tire size does a Yamaha YBR125 Custom use?
GarageDex's powersports data shows the Yamaha YBR125 Custom runs a 3.00-18 front tire and a 3.50-16 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like 3.00-18 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 Yamaha YBR125 Custom tire sizes change by year?
Yes - fitment differs across the years we cover: 2011-2017 runs 3.00-18 front / 3.50-16 rear; 2009 runs 3.00-18 front / 3.50-16 rear; 2008 runs 100/80-M17 front / 90/90-M18 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.
