The Moto Hispania RX125 is powered by essentially the same unit found in Yamaha’s successful YZF-R125. This liquid-cooled, four-valve lump is virtually unbreakable and runs sweet as a nut. Where the Moto Hispania’s RX125 unit differs from the Yamaha is it is fuelled by carburettor instead of fuel injection. The only downside to this is fuel consumption at 66mpg (average), down by 7mpg compared to the Yamaha’s 73mpg, and a manual choke is needed when the weather is cold. Other than that nothing is detrimental to its everyday running, though town or flat stick on the favourite ring-road. And yes, the RX125R is Euro 3 emissions compliant.
