Meteor Minor, Meteor Minor Sports, Meteor Minor Deluxe
& 500 Sports Twin
1958 - 1963

Billed as ''A 500 that handles like a 250'', the Meteor Minor had a shorter stroke than its predecessor and hence a much revvier engine.

496cc. Bore and stroke 70 x 64.5mm, Lucas alternator with coil ignition, 8:1 compression pistons, 30bhp @ 6250rpm. The final version, the 1963 500 Sports Twin, had a claimned output of 33bhp and top speed of 100mph.
Constellation
1959 - 1963

Fondly known as the Connie, Royal Enfield's Constellation was a snarling roadburner that put out an impressive 51bhp and had a top speed of 110mph. Sadly, it suffered from oil leaks and the scissor clutch was prone to slipping.

692cc. Bore and stroke 70 x 90mm, 8.5:1 high compression pistons, Amal TT carburettor replaced with twin 1 3/16" Amal 389 carburettors in 1960, Lucas alternator electrics with magneto ignition.
