Many riders immediately notice:
- Excessive engine heat

Why Harley Motorcycles Run Hot

Top Heat Reduction Upgrades Riders Are Installing
1. Performance Exhaust Systems
A freer-flowing exhaust helps reduce trapped heat while improving sound and performance.
2. High-Flow Air Cleaners
Better airflow can improve engine efficiency and overall rideability.
3. Proper Tuning
Many riders overlook tuning after modifications. A correct tune can significantly improve operating temperatures.
4. Heat Deflectors
Popular among touring riders for redirecting engine heat away from the rider.
