Hi Guys,

May seem an odd question but are Do Harley use AF or metric nuts and bolts, I have a Meterench Geman spanner system that will fit both but ' I'm not happy with the grip on the jaw's of the spanners, so before I start changing things I thought I'd ask the experts and buy the correct tools for the job.

Harleys use some ASE some metric.Seems like the brake and battery bolts are metric.

 

The only metric bolt that I've found on my Harley is the 12 point, 10mm bolts that hold the rear brake caliper on. There's probably a few more, but I don't know where they'd be.

 

The battery bolt is a 10mm.

 

The front forks, brakes and the battery also use metric bolts. The front forks are not made in America, I cant remember the name of the brand, I think its SHOWA, which is Japanese or something. Its a marketing strategy to have a certain % of the bike to be made somewhere else so that they could also be sold in other countries. Politics ...

 

MY battery bolt also takes 10mm wrench.

 

Actually it was a cost thing which goes back to mid '70's. H-D used to make their own fork lowers then switched to Kiaba then Showa and also the Keihin Carbs which they used up to '06/'07. The stuff was much cheaper than union made parts here in the U.S. Japan then to us is like China now.

 

they use both at least on my 08... trust me the only thing i have not removed is drivetrain...

 

Thank's guy's I thought I was going mad with some bolts taking AF spanners and others metric .

Ride safe.
