Suzuki variable valve timing. 1992

I remember when Suzuki introduced variable valve timing to the motorcycling world on the 1992 Bandit 400 and trying to figure out a mechanism that would allow that. 
So if you're an engine guy, give a thought to how you might do it- before looking at the image...  

This would add quite a bit of reciprocating weight in the valve train but it didn't seem to be an issue, the engine revved to 12,000 rpm.

very, very smart. It never ceases to amaze me, the creativity of engineers.

De Dion Bouton had variable valve timing in 1907, I drove one many years ago and a pleasant experience it was too. It's all been done before...
