I'm after some swingarm bobbins for the paddock stand.
what size are the bolt holes and what is a good make/style to fit?

Bump

Right these holes in the swingarm are M12 but i don't know what thread pitch

I have a tap which is M12x1.75 which isn't the same thread in the swingarm
So is it M12x1.50 maybe or M12x1.25
ANYONE IN THE KNOW

Not sure on the exact pitch , but its very fine . Just get a set from a Kwak dealer as the thread is the same as most Kwacks , well ZX9 and ZX7 . Take your bike down to the shop and try em out .
As for the design , they all work the same just get a colour you like , a bolt on its own works fine but looks shit .

Don't know what the thread is on the factory one's which big K actually got round to tapping out. Most left the factory missing the threads in there and have since been tapped out by peeps wanting to fit there own bobbins. See if yoyu can borrow a thread gauge of someone and check the pitch. I bought one the other week of evil bay for a fiver.

Cheers ears
I found these on flea bay

Update
Got these and they fit the KR1S bobbin threads
The only thing is the bobbins are slightly different to each other
(see pic)

Question is does one have to fit on one side to make more clearance
for the stand etc
