Very true. But this is on a RD350lc Hybrid not a Norton frame ;) and if you have ever seem Factory Jap welding from 30+ Years ago...NOT GOOD at all.. Hopefully the Brazing on Norton fames look nice..
 
Being metal ALL frame tubes will eventually rot, and this is why most of the British motorcycle industry went to great trouble to getting their frames stove enamelled so they still looked good 50+ years on if the frame was taken care of.
 
Like TT says, the road bike featherbed frames were all welded mild steel. Race frames were brazed.

No, their welds don’t fail either.

But they’re all bloody old and probably abused by now.

Areas to watch for include:

Rotten bottom rails

Rot and fatigue on the exhaust mounts welded to the bottom rear bend

Bent front down tubes caused by a frontal and / or being ridden without a proper structural head steady (an integral / structural part of the frame design)

Damaged bottom rail from a poorly fitted side stand lug and / or endless kick starting whilst on the side stand.

Cracked / bent / damaged engine mounts

Cracked / damaged lower cross tube.

A lot of decisions really depend on what your vision is for your finished product, how fussy you are, how much you can do yourself, and how much hard cash you’re prepared to spend.

But I’d caveat the above by also adding that we all ALWAYS under estimate the work, time and money it’s gonna take!

You gotta be honest with yourself though, no matter what BS folk try and feed you, the ain’t no such thing as a cheap way to build a nice Triton.

If you want a really good end result, and are prepared to spend, you could do a lot worse than speak to Mr Triton himself, Dave Degens, he still does new frames, engine plates, forks, pipes tanks, seats, etc and usually has a few used engines and gearboxes to sell.

It’s and old cliche, but he really has forgotten more about Tritons than the rest of us will ever know!

Dresda Triton vintage race bike. 650cc, pre unit, slimline frame:

Degens much prefers the strength of the unit engine, but, as some have said, they can look too small for the frame. This one doesn’t cos it was a new frame built for a unit motor. Which was 840cc and indecently quick:

Thanks Eddie..

I can do most of it myself "hopefully" Major Mechanical like a full bottom end rebuild will be left to the pro's. Any fabrication, welding, Prep, Polishing, wiring I can handle.... :eek: I know all to well about budgets,timescales.. My rd350 was 6-12 months project and i am now 24 months + in but now on the home straight.. Dave degens isn't that far from me so may give him a visit in the near future...

@Morgy if you don't get this, I might! That's a great place to start, if it doesn't get raised too much.

A little digging on the www. looks like it sold for £8600 Feb 2019.. Now on with different seller but with the same description and photos. Could be first sale fell through, so why different Account? or the new buyer found something up with it..
