Product Overview
DAYTONA 10MM YAMAHA TYPE MIRROR THREAD ADAPTERS, BLACK, H10, 2pc SET, 99583-4
The DAYTONA (Yamaha type) mirror adapter set are for mounting mirrors with M10 x 1.25mm (RH) threads to bikes that have RH thread (positive) on the left side, and Inverse (reverse) thread on the right side.
This is thread arrangement is common to most Yamaha models and some KTM models. While we do sell many mirrors with Yamaha threads or adapters, some mirrors with M10 x 1.25mm threads are only available with normal (positive or RH) 10mm threads. By using these adapters, it will allow you to expand the range of mirrors available to your bike and you can use all mirrors with normal (RH thread) using a 10mm x 1.25mm thread.
Perfect for customization or simply use for OEM replacements.

NOTES:
-> Some mirrors may have threads that are too long for the adapters. Check specs above. If so, we have adjustment washers sold separately.
-> Always check your bike has original factory (RH thread & Inverse thread) and mirror mounts are 10mm.
-> Always grease the threads (inside adapters and when mounting to the bike), with anti-seize grease.
-> Do not over tighten the adapters or mirrors when mounting as that can damage threads or mirrors etc.
