An I-engine is one for which an opened valve (or part thereof) may occupy
the same space as a piston such that, if the timing drive is off (i.e. broken
cam chain), serious (often terminal) damage ensues.
Are I-engines much in use in the motorcycle world? If so, which brands/models
use 'em,
which don't.
Just curious.
Thx,

Yes.

Most if not all modern bikes. Off hand I can't think of any that don't.

Why, are they putting rubber belts instead of chains now?

They don't stretch much and they don't rust, so, no maintenance?

And Morini was using them before that. Although they're not rubber these
days. Kevlar, IIRC.
