Sunbeam S7 Shows Simple Yet Appealing Post-War Design

By Paul Crowe

Here’s a really nice looking 1947 Sunbeam S7, a postwar model that looks as good or better than many of those other big name bikes of the same era.

The engine is a 24 horsepower, 500cc vertical twin sitting longitudinally in the frame which allows shaft drive. The shaft drive turns a worm gear which is not something you see every day, The rear wheel has a simple plunger suspension.

Not a bad looking bike from any angle,

Evidently, the performance isn’t overwhelming and some would fault the suspension for less than sporty handling, but I really like the look. It’s far less busy and cluttered than a lot of Harleys and Indians of that era and won’t get lost in a sea of lookalikes.

Even on the engine, everything is hidden away to keep the lines uncluttered

Reports from owners say the reliability is high and if you’re looking for a bit of attention on bike night from a design that makes plain you don’t have to be painted in wild colors with sharp edges to catch someone’s eye, this is your machine. I like it. It’s for sale on eBay. auction ended

    The ’47 Sunbeam looks great. I wish someone built a shaft drive bike with comparable looks today.

      Beautiful bike! There is a similar Sunbeam here in St Louis Mo, in Carl Donelson’s collection at his shop. I think his is a pea green color.

        I think the green ones were the later ones, though I could be wrong about that. Nice design either way.

    The S7/8 came out after Sunbeam was absorbed by BSA, hence the BSA cycle parts. They certainly look good but have a poor rep for reliability, not lease due to overheating of the rear pot. And they really are underpowered. If I was looking for sturdy, no-nonsense transport I’d be inclined to look at Beeza’s contemporary B and M ranges.
