1966 BSA Bantam D10 Sports
The standard D10, which came in mid-1966, had something like 40% more power than the D7. The D10 Sports offered even more, having a four-speed gearbox and the new Amal Concentric carburettor. It also looked the part too, with its upswept exhaust, humped seat and flyscreen. Top speed was just over 60mph (not much more than even the old D5) but it looked faster and the extra cog made it all so much easier
