Plate is often heat treated after rolling too though!

So for example 6082 T6 is a pretty go to material, the "T6" refers to the heat treatment it's had. A 250mm square of 40mm thick material would only cost you £95 as a member of the public, so you can probably guess how little it costs in industry. 6082T6 would make you some nice yokes, certainly compared to stock casting (I'd bet).

EDIT: BTW, if one thing should be clear from this conversation, it's that putting two yokes next to each other and declaring they perform the same because they look the same is a very bad idea

Tricky wrote: Wed Apr 12, 2023 8:22 pm They are Ohlins forks in my model- I don't know whether Aprilia buy the whole assembly including the top yoke from Ohlins or just the fork legs, but whatever, the top yoke is quite different (and a lot more substantial) looking than the one on the non-Ohlins variant of the Tuono.

Tricky has the super-posh and rather rare Factory version with Ohlins everything. Council spec Tuonos made do with Showa forks and Sachs shock.

To attempt to get another opinion on this I rang Griff Woolley of AP Workshops fame and all round good geezer and asked him a number of questions. He confirmed that the 'Showa' Tuono top yoke is cast, as are the Mille/Falco yokes, but the T yoke has revised webbing for additional strength in key areas. But they do also poke a 10mm hole in it to fix the risers to, and the top deck of the T yoke does look identical to the M/F yoke.

I then told him what I'd done to beef up my Mille yoke and asked him his opinion. Without hesitation he said, 'yeah, that should be alright. If you'd just drilled a hole in it I'd tell you to stop, but what you've done should be fine'.

So there we are - completely unscientific, but a view from a man who gets his hands dirty working on bikes 5 days a week and is very highly regarded in the Aprilia community. That's good enough for me.

Flame away...

Tricky's is a fancy one with Ohlins, the cooking spec (Showa) one is cast is what I read.

Could be they just made a beefier (i.e. stiffer) one for the fancy models.

No, I'm not. I have no idea whether Tricky's yoke is cast, machined from billet (or machined from cast). I'm saying the base model (non-Factory) Tuonos with Showa forks had cast yokes.

Ha! If funds were unlimited, then maybe. But I'm very happy with the performance of the Showa forks, Brembo calipers and Oz wheels, so I'll just be changing the top yoke. And the risers and bars, obvs.

I mean - you wouldn't want me to go back to this would you?

I don't think anyone wants that !

I'm shocked, honestly that you ever thought they were acceptable

It was a case of 'I'll just extend what's worked in the past', really. It was only when I came face to face with the actuality of them fitted that the awful realisation dawned. Not one of my better ideas...

Still, at least it gave a few people a good laugh...

I just can't fathom how you ever looked at it and went "yip, that's what I was going for"

And you were worried about the new ones!

RTTL. Making the interwebz a safer place one yoke at a time.

Have you considered just buying a Tuono?

Crazy talk.

Think of the entertainment for people in 10 years when someone says "did you see what this guy did"

Do you remember that guy who's modifications encouraged the government to introduce TUV stylee modification enforcement in the UK?

Well we all remember Bellwoods crimes against the fashion police

I'll never forget Daven's plywood tacho

Some things just go down in history.

These risers have a place in that list

Mango - you do know that you can get clamps that go round the forks that allow you to use normal handlebars, I've got some 43mm ones from moto-cnc that work fine and if anything are a bit heavy duty for the job.

Could be worse, skip to 1 minute

As we are still ribbing mango, can we just spare a minute to remember Supermotospike, whose engineering ambition severely outweighed his ability.
It's a sobering reminder if it does go horribly wrong!

I don't believe I ever did! I had my blinkers on at an early stage and could only see that way of getting the bar rise I wanted. It really was tunnel vision. And I knew it looked gash, but couldn't admit it to myself. But the forum provided me with a robust therapy session and some tough love and showed me the error of my ways.

I have seen the light, brothers...

Nope. I have a Falco that can do that...

Unless of course you're referring to a V4 Tuono. I do not rule out buying one of them.

Yes, I am aware of those. I guess I view them as a Plan C, but hopefully Plan B (Mt-09 risers mated to modded RSV top yoke) will work out.
