Ram Mount Question

I want to put a Ram ball mount on the handlebar risers, is the bolt that holds the handlebars on 1.25mm or 1.5mm pitch?

M8 x 30, gotta be 1.25mm pitch. I don't think they do a 1.5mm pitch.

But the Ram mount is imperial (actually SAE) thread, i.e. in inches.

I use a handlebar U-shaped clamp provided by Ram on my GRiSO's radar detector mount, I placed it just to the outside of the LH handlebar mount. the radar detector needs to be operated by the left hand, otherwise the throttle gets closed!

The top clamp bolt is M8 x 30
The flanged bolt from the underside is M10 x 40
Without removing one I can’t tell if they are fine or coarse but would expect these to be fine.
M8 fine = 1.00mm
M10 fine = 1.25mm

many thanks

These should be coarse threads - fine are like rocking horse poo (a bit hard to find). The only fine thread (I think) is the thread on the engine temp sensor. I have replaced these bolts on mine from our "normal" stock, which are all coarse.

8mm - 1.25 pitch is coarse (fine is 1.00 pitch)
10mm - 1.50 pitch is coarse (medium is 1.25; fine is 1.00)

All of the even sizes (2.0, 3.0, 4.0 etc etc) have a fine/coarse; 5.0, 10.0, 12.0, 14.0, 18.0, 20.0 have a fine/medium/coarse pitch. Half sizes (1.5, 1.6, 1.8, 2.2, 2.5, 3.5, 4.5 & 5.5) have only a single pitch - though you will not find them on our bikes...

Funnily enough, the drill sizes for tapping these holes are mostly number/letter drills, or plain old imperial. Weird huh!

Just saying.

Cool. I didn't know you could get the balls to mount like that. I've been living with this horror show.

I guess my question is has that ram mount shown got a metric thread?  Or is it "hollow" and any suitable bolt can be used?

It's just a hole. The kit comes with three M8 bolts (or screws) of 55, 60 & 65 millimetre length. The HD crowd have to source 5/16" hardware.

That is exactly the solution i need :-)

It does look as though your instrument panel seems be flatter fitting than mine, or is it just the angle of the piccy?

That truly is ugly, i had a similar installation and was so aesthetically offended by it that i would spend the time taking it on and off every time i used it!

Hi - its just the standard dash - must be the angle as you say - got the ram mount from infinity motorcycles - about £15 if memory serves me right... torque it up and you're off!
