Difference between M & super M?
Postby Mach-z » Mon Sep 24, 2007 2:40 am. The "BIG" differance that is very easy to see is the change over to disc brakes from band brakes . The Super "M" has a stronger transmission [ stronger bull gears and axles], 10 hp more 264 cubic inch. The brakes are a dead give away, there is no debating on the differance.
