The Triumph 21 appeared in 1957 and enjoyed a nine year production run ending in 1966. Depending on who you believe, the name "21" or "Twenty One" was chosen either because (a) it celebrated 21 years of the Triumph Engineering Company Ltd (formed by Jack Sangster in 1936 when he rescued the ailing Triumph Motor Company which in turn had succeeded the Triumph Cycle Company Ltd), or (b) because the Triumph 21 is nominally a 350cc motorcycle, which is 21-cubic inches in US-speak (the actual capacity is 348cc).

 In post war Britain, exports to the USA were a vital source of national income. In fact, "Export or die" was the establishment mantra.

We think the 21st anniversary explanation is more likely. Triumph, after all, wasn't in the habit (neither before nor after) of listing the capacity of its bikes in cubic-inches, and 21 years is, and was, a natural "coming of age" celebration.

Either way, the Triumph 21, with its 58.3mm x 65.5mm bore and stroke was the first unit-construction engine produced by Triumph for general production.


Triumph 21 engine


It was first badged as the 3T and offered around 18bhp at 6500rpm. The compression ratio is a moderate 7.5:1. Maximum speed is around 70mph. Fuel consumption is 60 - 70mpg. The electrics are 6-volt (with distributor ignition). Brakes front and rear are drum.

The engine features a "360-degree" crankshaft (pistons rising and falling together), a cast iron cylinder block, aluminium alloy cylinder head, and separate rocker boxes. And like most Triumph motorcycles, it was aimed at whoever could afford it.

The Model 21 was designed by Edward Turner and Jack Wickes (Turner's "pencil"). What made the bike visually striking was the "bathtub" or "dustbin" rear enclosure. Matched with its "Roman helmet" front mudguard, the Model 21 was typical of Triumph General Manager Edward Turner's desire to keep things clean and uncluttered (as evidenced by Triumph's earlier headlamp nacelle concept).

The general public, however (particularly the Yanks), didn't much care for the extra tinware. It added weight and complexity, and because of that many riders removed it and trashed it (thereby raising prices today for original examples).


Triumph 3T & 3TA


But the Meriden factory persevered, and abbreviated the bathtub and finally removed it entirely. By then (mid-1960s) what had started as the Model 3T and had morphed into the 3TA ("A" for alternator to distinguish it from the original dynamo bikes) was a little long in the tooth. The 350cc capacity had lost favour. Buyers wanted either bigger or smaller, so the 3TA was withdrawn from sales.

Today, the bikes are considered "charming" and even "cute", but the styling still isn't everyone's cuppa. But here at Sump, we like 'em plenty. Like the larger 500cc 5TA "bathtub" model, the 3TA is a mild-mannered, undemanding, fuss-free bike.

It's easy to work on (although the rear panelling adds to your maintenance workload). The clutch and 4-speed gearbox give little or no trouble. It starts without much effort, and it stops reasonably well enough for the performance.

In short, it's a minor Triumph.

The size of this Triumph 21 metal sign is a generous 300mm x 410mm, which is roughly the size of two A4 sheets of paper. The image is 1,400 dpi, which is way better than most, if not all, of the lesser quality stuff on the market. And the edges are rolled to help preserve those delicate finger nails.

Also, these Triumph 21 wall signs are printed direct to metal in the traditional way.

Will you like it when you see it? We think so. If we didn't, we wouldn't be flogging 'em.

We package these signs as well as we reasonably can, and we despatch as soon as possible (usually within 24 hours of ordering, and very rarely longer than 2-3 days if stock has run out and needs to be re-supplied.

Either way, we'll keep you posted. And if for any reason we can't supply your sign, we'll tell you without unnecessary delay and will refund your money in full.

And remember this if you will:
We don't sell anything that we don't hang in our own garages.
