HARLEY-DAVIDSON** Wrench Head Size
Pre-1980 ** 5.6 F/R **
1980 to current ** 6.0 or 6.2 (see below) **

We have narrowed down the Harley-Davidson applications to 3 sizes, 5.6, 6.0, and 6.2. This has been very difficult due to the vast number of units sold. Above are the head sizes that Harley Davidson orders from us as well as the general size by decades.

Rad Wheels require a 6.2mm head.

Warp 9 Wheels require a 6.8mm head.

If you have any questions or feedback shoot us an email or call so we can get you the correct head for your wheels.
