Frequently asked

What tire size does a TM Racing EN 125 use?

GarageDex's powersports data shows the TM Racing EN 125 runs a 90/90-21 front tire and a 120/90-18 rear tire. Tire sizes vary by year - see the table for each range.

What do the tire numbers mean?

A size like 90/90-21 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 TM Racing EN 125 tire sizes change by year?

Yes - fitment differs across the years we cover: 2019 runs 90/90-21 front / 120/90-18 rear; 2016 runs 90/90-21 front / 120/90-18 rear; 2012 runs 90/90-21 front / 120/90-18 rear; 2010 runs 90/90-21 front / 120/90-18 rear; 2008 runs 90/90-X21 front / 120/90-X18 rear; 2007 runs 90/90-21 front / 120/90-18 rear; 2006 runs 90/90-X21 front / 120/90-X18 rear; 2005 runs 90/90-21 front / 120/90-18 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.
