Someone with less manners than me would mutter helical gears have no place on a racebike.. ....

I agree, but I doubt it was the reason the clutch basket was destroyed.

Yeah fair enough, although it wasn't my thought that it was the cause, I will defend it anyway, thinking about it as they side load the bearing it must place some on the hub also if well when the bearing does start to fail as well.
My moneys on 30 plus year of stress and metal fatigue handing far additional stress than the 12hp and 5 year service life envisaged by Suzuki.

There appears to be a lot of localised wear in the tangs of the plates i can see the appears to be huge amounts of stress raising sharp edges on the debris. These baskets are made from basic casting not designed for stress involved in race engines. they often have more meat in areas where they don't need additional material and a lack of decent radii and meat in areas where the basket goes from basket to the hub.

I don't recall how Suzuki mounts the gears but I assume its pressed in rivets like Honda these often also wear over time creating additional stress.

TLDR The design ethos that placed quietness of primary gears as a priority over power efficiency flowed through to having a part that was not designed for year after year years of up and down race changes with 3x the design hp.

... just too much power 😂
I think the part was stressed a lot over
its intended capabilities and so fatigue
comes into play.

You could try to reinforce the clutch basket
with a thin steel ring.

You could reinforce it like this

I can back that up. As I had a engine that just lost one finger of a clutch basket and did that exact thing to my next basket and had no more problems.
