What the number itself says

Reading 7RUNX.300XM5 left to right: 7 is the model-year letter for 2007, RUN is the three-character code the EPA assigned to RunMaster as certificate holder, X marks an off-road certification, .300 is the displacement in litres, so 300cc and XM5 is RunMaster's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

The engine, as described on the certificate

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor, run by an ignition control module (CDI-type ignition). There is a catalytic converter in the exhaust, recorded as "TWC, single bed, open loop". The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 12 kW (about 16 hp) at 7,500 rpm, driving through a 5-speed manual gearbox.
