Check the size (diameter) of your current headlamp and the mounting method. Most headlamps in our range are universal and work with standard headlamp brackets (5.75 inch / 7 inch). If in doubt, contact us with your motorcycle model.
LED headlamps provide brighter, whiter light and consume less power than halogen. They also last longer and produce less heat. For classic motorcycles, a halogen headlamp is sometimes preferred for a more authentic appearance.
Most headlamps in our range are E-approved (ECE certified) and therefore legal for road use. Check the product specifications for the exact certification.
