Frequently asked
What tire size does a Buell Lightning XB12S use?
GarageDex's powersports data shows the Buell Lightning XB12S runs a 120/70-ZR17 front tire and a 180/55-ZR17 rear tire.
What do the tire numbers mean?
A size like 120/70-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.
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.
