The 2025 Honda XR650L continues its legacy as a true dual-sport legend, renowned for reliability both on the trail and on the street.

Why Air Filter Maintenance Matters

When to Service Your Air Filter
- Check every 500 miles or after every ride in dusty conditions.
- Replace or deep-clean the filter every 1500–2000 miles, or immediately after heavy off-road use.
