RGS Headstock Cracks - an experience to share

Frame, shaft housing, meh, what the hell...

My good friend Mr Cudlipp (BFN hons) got that done on my Sprint as a priority job,when he restored it in the days when I had no garage.The other priority was supplying him with copious amounts of Doombar. :LOL:

Would this frame cracking problem be lesser if say someone made up two thicker triple crowns, so that the lower one would have double or triple bolting each side and thereby gripping lower down on the forks?

I did see this from for example Moto Officina di Angelo Cleva, but when I kindly asked him how much, I got a quote of half the bikes total worth, mglp. I did try to talk over the friendly gentleman in Australia who did some many years ago, but unfortunately to no avail.
Anyway, someone do these today for the sfc1000? And will they help the aforementioned problem, apart from the gusseting as Laverda described?

Kind regards,
Jacques

I should think that a more rigid fork would make the frame cracks more likely.

Agreed and that I believe, is also what Piet said. It should be interesting though, if using better fatter (carved out, triple crowns which reaches further down), in effect making the inner legs shorter, would help achieving lesser stress - lesser cracks in the framing tubes.

If your fork tubes are bending less, the frame will be bending more.

Grant (no longer posts) extended his head tube below std, used a longer triple clamp/crown shaft and braced from the extended part to the down tubes. Clever idea, as it also reduced the free length of the looong forks on the triples. You can search and find his old thread. What was the name of his modded triple???
