The Honda XR80 typically uses a 14-inch front wheel and a 12-inch rear wheel, with common stock tire sizes around 2.50-14 for the front and 4.60-12 for the rear. Exact sizes can vary by year and model, so always verify for your specific bike.
The XR80 is a small-displacement dirt bike that has seen several generations since its introduction. Because Honda tweaked wheel sizes and tire options over the years, riders and restorers often encounter a few different stock configurations. This guide lays out the most common sizes you’ll encounter and how to confirm the right fit for your bike.
Common tire configurations by model year
Below are the tire size configurations you’re most likely to encounter on a Honda XR80. While not every year used every size, these pairings represent the typical stock options you’ll find in manuals, parts fiches, and bike racks.
- Front: 2.50-14; Rear: 4.60-12
- Front: 2.75-14; Rear: 4.60-12
- Front: 2.50-14; Rear: 4.50-12
These configurations reflect the common 14-inch front and 12-inch rear wheel setup across XR80 variants. Exact year-by-year specifications can differ, so use this as a guide and verify your bike’s markings and documentation.
How to confirm the correct tire sizes for your XR80
- Inspect the sidewalls on your current tires for size codes (for example, 2.50-14 or 4.60-12).
- Consult your bike’s owner manual or the official Honda parts fiche for your exact year/model.
- Measure wheel diameters if you’re unsure: approximately 14 inches at the front and 12 inches at the rear.
- Ask a dealer or experienced XR80 community members to confirm year-specific requirements, since some early and late editions diverged slightly.
Once you’ve confirmed the exact sizes, you can select tires that match those specifications and follow the manufacturer’s recommended tire pressures for safe performance.
Choosing tires for performance or restoration
For riders prioritizing trail grip and reliability, stick to OEM-sized tires or reputable equivalents in the 2.50-14 / 4.60-12 range (or the closest match for your year). If you’re restoring a classic XR80, maintaining original sizes helps preserve handling characteristics consistent with the bike’s design.
Summary
In most Honda XR80 models, the standard tire setup is a 14-inch front wheel with a 2.50-14 tire and a 12-inch rear wheel with a 4.60-12 tire. Variations exist by year, so verify the exact sizes on your bike through sidewall markings, the owner manual, or the Honda parts fiche for your specific model year. With the correct sizes, you’ll ensure proper clearance, grip, and safe riding all year round.
