The D14 was merely a tuned version of the D10 (in typical Brit tradition) that was quickly replaced by the D175, which featured a stronger crank, crankcases and clutch. The D175’s the best Bantam, with all of the good points and few of the bad. Performance’s adequate, handling’s taut and the braking’s passable. Try to find a stock engine, some were tuned to as much as 20hp, which is big bang time! Some nicely renovated bikes.
