Gosh, steel or not, I cannot see a lot of stability with a skirt that short.

I see a lot of short skirt pistons working on modern 4T MX dirt bikes. Almost all of them are like that now and most rev over 11,000 rpm. You have to replace them far more often vs the old school long skirt pistons as wear can hurt stability.

Just to note, these are aluminum pistons and not steel like this topic is about.

Kawasaki KX450 (BTW, that's a Carrillo piston!)
