1976 Penton 250 MC5 Motorcycle Road Test / Photos / Specs

Buying the best motocrosser is no simple task these days. Time was, only a few seasons back, when price for the most part indicated which race bikes were superior. The expensive European mounts were clearly better motocrossers than the less costly Japanese bikes. But the tide has changed, and price alone no longer singles out the best – or worst. Honda started the change with the Elsinore, Yamaha emphasized it with the YZ series and Suzuki’s RMs are tearing up tracks from coast to coast. Still, the Europeans have not been sleeping, though their bikes have sen less dramatic improvements. Maicos, Huskies, Montesas and Bultacos are proven machines, and finally Penton has developed its first real motocrosser – the Grand Prix replica 250cc MC 5.

The Penton Story: Back in 1967 John Penton had a dream. He dreamed of a competition motorcycle designed for Americans by Americans. Being one of the United States most consistent and well-known Enduro riders with a long list of National Enduro wins and the National Enduro Championship to his credit, he still was not satisfied with the competition machinery available on the market. He found that to be competitive in cycle racing, it required too many modifications, extensive upkeep and a knowledge that few riders had. He kept dreaming about that machine until one day he dcided dreaming was not enough and packed up his 25 years of experience and went shopping in Europe. There KTM of Austria took a look at John Penton’s plans and together came up with the Penton Motorcycle. A machine that was to alter the course of American motorcycling in the years to come…
