2022 machine is fully equipped for modern life. There’s fuel injection, of course, plus liquid-cooling and Euro 5 compliance.

Chassis-wise, there are Brembo brakes, ABS, and grippy Pirelli Phantom Sportscomp tires. There are no electronic aids or rider modes, and more controversially, no kickstart.

It produces a perky 45 hp at 6,500 Rpm and 40.6 lb.-ft. at 4,000 rpm. There are just five gears on board.

The gearbox is smooth, and with the big single making usable torque from 2,000 rpm (peaking at a lowly 4,000 rpm before tailing off) there’s plenty of puff to keep it ahead of the traffic at the lights.

The twin-spark DOHC single started life as a Rotax and was developed for the Goldie in collaboration with Ricardo, the famous engineering company.

Goldie is also more than capable of cracking a ton: of breaking the 100 mph barrier, which the postwar bikes were so famously proud of back in the days of limit-free roads and flat caps.

In top gear, 4,500 rpm equates to 70 mph, but the new Gold Star will happily cruise at 80 mph (5,000 rpm) and still has enough in the bank to slip past faster vehicles.

I saw an indicated max of 109 mph, which somehow felt as thrilling as far greater speeds on other bikes.

The single 320mm disc up front is worked by a dual-piston sliding Brembo caliper that suits the easygoing nature of the machine.

The BSA weighs in at a claimed 437 pounds dry (470 pounds ready to go), so is relatively light compared to other bikes in this category.

Twin shocks on the rear are only adjustable for preload. But the ride is controlled and damping rates are pretty much spot on for what is, after all, a low-cost machine.

Ground clearance is good, and the Goldie warmed to the Millbrook sweepers, encouraging me to let go of the brakes and let the bike roll into the track’s open corners.
