Hmm, how do you specify load on a rod bearing? I've only really used them on gear levers so no drama, but my RSs came with brake arm ones from Honda and shock eye can get hammered and do wear and fail of course.

Mine will be floating caliper I was thinking no issues as it's in compression but kicka is actually right it will be in extension. I haven bought the rose joints Yet but I might go up in gauge on the alloy rod the later ones actually used carbon tube.
But this is forbotten under pre 89 unless original equipment like ciba rg500 Herron?

Make it out of Nolathan so it has a bit of give.

Bamboo would work, it has excellent properties as a natural composite I am not worried about the rose joints as if it collapses it would only move a few mm.
The rose joints ripping out of the tube would be a different story in extension, so my idea of inserting a rivenut into the tube will not be that smart.

gen corse hads a 190mm 3 bolt disc on a smaller centre as I cant afford the marvic ATM I can only go as small as 220 maybe 210mm
I can use a disc from a YZ 89-98 ish which will bolt on and be 220mm down from 245mm std but I will need another caliper bracket to do that and if I did that I would be better using a lighter caliper like the Corse.

I wouldn't care so much on a gear selector

I remember looking at a chart with some type of rating for rose joints, cant remember how it was measured or what was measured, $100 was the cheaper 8mm size we used on the LCR in the good quality stuff, as soon as there was any detectable play in them they got replaced, the less expensive rose joints we tried lasted a far shorter time

You can buy pre threaded plugs to weld in, but the plugs wouldn't be hard to make anyway, you can also buy pre made rods threaded at both ends for female rose joints in various lengths although we only got them in steel

Yeah the sizing compared to tube is a pain, so I will have to make/buy an insert.

Looks like Eraldo was onto it with the extra intake years before me on Dougs bike.
They look asymmetrical to me?

Having owned a 1982 Darmah and a 1985 MHR Mille I don't even consider any Ducati with belt driven cams a "real Ducati" (maybe the F1 750 gets a pass)

i seen this pic the other day and thought of this post warwick.
The Pantahs were designed by Dr Ig as the successor to the bevels. With bordi adding a 4 valve top end.
So even the designer of the bevel twins seen this as the way forward.
The 851/916 and the F1750 plus the MV750 DB1 the 500gp Cagiva, the mito were all styled by the same dude Massimo Tamburini.

pic 3 is pretty cool three world champs at Mansfeild. Croz, Hugh Anderson and Roche
Pretty sure croz was still test riding for Moriwaki then.
