Ray,
Brown & Gammons build racing XPEG engines that are reputed to put out
about 145 bhp. These use a flywheel that can best be described as
resembling a bicycle chain-ring - there's a periphery that supports a
ring gear, a flat surface for the clutch to attach to and bite on, and
not much else! I'm not sure how much (or, should I say, how little) it
weighs but it isn't very much. My experience of one of these in an engine
is limited to driving the ex-Ken Miles R1 a few years ago, after it had
been fitted with a number of B & G's trick bits. It certainly revved
freely (close to 8,000 rpm) and crisply and exhibited no lack of
tractability that could not be attributed to the racing cam.
