RE: DA, BME, ZDZ 50??
The only thing I don't like about the BME is the amount of unsupported crankshaft. Apart from that it seems cool despite no reed valve. Weight with basic silencer is advertised as 3.3 pounds. Best of the bunch as far as I can see. My Moki 1.80 weighs 3 lbs with BCM muffler and getting near 3.5 with the radial mount.
