    Re: 2014 Yamaha YZF-R6 Headlight Cap Adapters.

    These are great. Looks and fit like OEM, but better depth to be able to fit aftermarket (longer) headlight bulbs like LEDs. On a side note, their customer service is awesome, they respond super fast, I mean instantly, and they will accommodate you even if the cause of the issue is out of their hands.

    I brought these for my 08 R1 and couldn’t be happier. The fit and finish is fantastic. The look completely OEM and just work. Shipping was fast too. I often recommend this product to other riders looking to swap to LED headlights as they’re an exceptional solution
