Lot Details
1972 Triumph Daytona/BSA B50 500cc Special
Engine no. JG32772
Triumph’s compact and readily tuneable 350/500cc unit-construction twin-cylinder engine has long been a favourite of specials builders intent on creating a relatively light machine capable of punching above its weight. Many have been installed in Greeves scrambler frames, this particular combination proving so popular that the ‘Tri-Greeves’ has virtually achieved marque status. This particular machine uses the oil-bearing frame taken from another successful moto-crosser – the BSA B50 MX – and a tuned Triumph Daytona engine. The latter has been fettled by none other than Dave Degens, incorporating a re-machined and squish-banded cylinder head, slim-stemmed valves and new Amal Concentric 30mm carburettors. Other noteworthy features include Lucas RITA electronic ignition, twin-leading-shoe front brake, alloy fuel tank, alloy wheel rims and race tyres. CRMC and VMCC approved for classic/historic racing, the machine has not been used for over a year but is nevertheless reported as running strongly. Offered with restoration invoices.
