I had a similar issue with my YB7. NEEDED THE SEAT bolts.
I found some shouldered bolts on eBay.
These are construction bolts. They have a cap head (hex). Then it goes into a shoulder that is thicker than the thread. I think the shoulder on mine was 20mm but it was the right size for the YB7. Then there is a shortish thread. In my case 16mm.
The bolt length and shoulder come in different lengths.
I had to machine the shoulder a few mm and then I put a taper on the socket head.
The bolts are a few Bucks but way cheaper than Bimota spares. I think I got them on eBay, but any good bolt supplier can supply. Plenty of on line catalogs to find what you need.
Material is hard steel.

Shouldn't be an issue....they fit into proud sockets with flanges....and....you should have as standard a double layered as heat baffle unit that covers the link pipes

Just to advise, i’ll let this run for the next week and see where we have got to at that point! Thanks for the comments so far.

I have a friend in Aus that makes 'special' bolts, fasteners, spacers etc as a hobby. He mostly use titanium but can use steel, alluminium, titanium etc. He also has the rotary broach to do the in-hex. I'll bounce it off him and see what he could do.


I've no idea what the rotary broach is Brian....but lets see....I presume you have the same plastic/nylon bolts on your Junior?



Yep, my Junior has the original plastic fasteners.


Ok.... so I thought my DB2 J had plastic fasteners.... on closer inspection I’ve found that they are indeed black anodised ALUMINIUM! I’ll post a couple photos in my Junior refresh thread

These should be the same as the ones used on the exhaust of a SB8R?

IF so, I would be down for some as well.

Hi, Im a couple of days behind on this due to other work at the moment around the house! Will post up a dimensioned drawing for you to check. In any case I’ll have to get a quote for a reduced number as not enough takers for the originally discussed batch size. Crying or Very sad

as I said mine isn't standard and are 2 large diameter pipes - no Y piece. Only 1 layer of the baffle plate will fit and the pipes sit 8mm below it in parallel - that's why it all gets a bit warm when your out on a decent run.

here you go Jaguar. (Nb there will be a 1mm 'band' at the base of the screw's head ie the taper isnt the full 4mm depth if that makes sense)

an aside from the seat bolts but could Zircoflex sheet be your friend here?
