Interceptor Mk2

736cc ohv twin || 442Ib || 112mph 50mpg || 1968-70

A serious contender for Britain’s best-ever big parallel twin. A super redesign of the old engine lifted it into the near-bulletproof bracket. Crushingly handsome good looks, good handling and an immense power spread, and no oil leaks, which was partly down to a crankcase redesign and a change to wet sump lubrication. Royal Enfield’s brief acquisition by Norton Villiers brought Norton forks and front brake. The only let down is the gearbox, which has a big gap between third and top. If you have lots of money, consider a Rickman Interceptor. Or if you have lots and lots of money, a Clymer Indian Interceptor.

Prices: low £5500 || high £11,500
