ROYAL ENFIELD BULLET 350

The Bullet is neater, lighter and sportier, and got a swingarm when launched in 1948. They also leak more oil, have less positive gearboxes and are a little more fragile, possibly because they were tuned for speed. They can be turned into effective offroad tools, too. Pay from £3000 for a good runner, or from £1500 for a more recent Indian-made example.
