The 500 version of the AMC single really is a bigger version of the 350, with a bit more of everything – especially torque. Excellent riders’ machines, these are classics in every way. They share almost all the components apart from the piston, flywheels, barrel and head, with the smaller engine. The 500 is a pleasant tourer with good handling and comfort allied to a loping 60mph cruising speed. We rather foolishly never followed up on a really nice one at Netley a few years back for less than £3000 and have regretted it ever since.
Prices: low £4000 || high £8000
