side stand/ lower mounting stud nut size

[davidsmirage]

As the title asks. Does anyone know the size of the lower engine stud/side stand nut?

Thanks in advance.

Yes 

 

[davidsmirage]

LOL.

Could you let me know it as well please?

Cheers

Yes, I know it as well... but as you asked in a nice manner, M10x1.25.

I was intending to give the answer, but Piet beat me to it while I was reading other posts

Metric fine, M10 x 1.25 and small hex too (14mm across flats on memory)

Surely 13mm?

I'm pretty sure that 14mm is the size socket I used last, but I'll check later 
The DIN standard for M10 x 1.25 reduced hex is 14mm A/F, full hex is 17mm A/F.
Of course this Laverda we're talking about, so it could be anything!!
13mm A/F would give you 1.5mm wall thickness, I'm guessing 2mm wall was more suitable?
Years back I put my late 180 Jota (120 cases) back and the nuts were butchered, so I turned up M10 1.25 nuts out of 17mm A/F bar, it just fit, the only downside was that I also had to turn down a socket to fit in the bracket!!

Every one I have seen for that engine mount is 17mm across flats.

Small hex, ie 14 or 15mm, wasn't around in Europe for general use (maybe for aerospace applications) when the bike was built.  17mm tall hex was stock fitment, same as the rear engine mounts.

DIN hex for M10 is now 15mm, probably a weight-saving exercise on the part of the european automotive industry, don't know why the japanese standard of 14mm isn't universally adopted.  14mm/flanged can also be found here and there.

I don't remember having seen a 14mm on a Laverda. I don't have a 14mm spanner in my tool kit.

Only on the throttle cable adjuster where it enters the switchgear.
And any banjo bolts on the hydraulic brakes.
