Grab Rail Bolt Length

[kevinw]

I know the grab rail bolts are M10 but does anyone know what length they are please?

I'm taking the Metal Mule rails off which have been on there since it was new and don't appear to have the original bolts (the MM ones are too long).

Thanks.

Answered elsewhere - 50mm.

Actually, it's 54mm. Part # 90111-10054-00, the 10054 tells the spec, first 2 digits 10 mean 10mm bolt, the last 2 digits 54 mean 54mm length. Not all Yamaha bolts use this numbering system, but many do.

FWIW, using dial calipers accurate to 0.001", the grab rail bolt on my 2019 measures 1.965" / 49.91 mm under-head length -- i.e., 50mm. Part number appears consistent between Gen-1 and Gen-2.

Had the bolt out already because the gf doesn't like the grab bars installed.

Thanks both. I misread the post from my other informant who said they were 55mm. I got some 50 and 60mm bolts and the 60mm seem to fit OK.
