Nigel Clark, pics by Chris Langton BSA Poster for the Spitfire Whether the Americans truly desired the specification of machinery that we sent them, or whether it was merely the interpretation of the factory stylists in their smoky offices of the 50s remains arguable. However, one thing is for sure, these days in particular, that era of Trans Atlantic styling is eye-catchingly different… BSA Spitfire Scrambler In this old motorcycle game of ours, fate can sometimes play a decent hand by laying in front of us a certain path, which eventually results in a machine that originally was not quite what we had planned.
Well, OK, not literally, but had it not been for a pal in need of a replacement alternator for his car, Dave would not have received the remains of a BSA engine in exchange for the required electrical component.

Usually on the front engine mounting lug. The oil in frame B- series are stamped on the prop stand bracket. Engine markings Engine numbers are easier to find usually by the crankcase mouth on the primary side. Exceptions are the Bantams which could be stamped on the front mounting point or just behind the crankcase mouth. This is just a guide and will fit most situations but frames were legitimately re- stamped by dealers if the original was damaged and a replacement fitted. These could be stamped anywhere and often were not stamped at all!
Identifying engine and frame numbers, season onwards. Owners with late model BSA’s can easily identify the month and year of their machine as the factory adopted a dating system for frame and engine numbers for the season models. As with all previous BSA seasons the model year started after the factory shutdown in July so that models were those made from August , through to July They would however have some machines in stock so that so that it is possible that a July model may be to either the previous or the next year’s specification.
The code consisted of three parts, the first as two letters giving month and year respectively, the second was a five digit number and the third a model code.

In these cases examination of the frame number — where it is, what it is, and how it is, may be of some assistance at least in allowing other specialists to hazard a guess at the true origin of the frame or machine. These publications have been invaluable in adding accuracy to the information — but even including their data there are still well over makes of possible lightweights to be confused over!

However, using those characteristics can be horribly misleading. In other words, this article will act as a guide, rather than a map, revealing land marks, rather than sign posts. You might not find the correct house, but you will at least end up in the right neighbourhood. Let’s assume, for the moment, that cutting edge Velo technology is reserved for top of the line, or close to it, models. And, let’s also assume that, sooner or later, the top end technology will trickle down to lesser steeds.
Assuming that to be true, one must understand that the trickle down system, spans both years and, often times, decades. With decades in mind, consider vintage road bicycles from the fifties, sixties, seventies and eighties. Though the bikes all look much the same, as they blend through the years, there are distinct frame characteristic differences that suggest age.
Remember, the clues offered by the frame set, with respect to its vintage, are only clues and not perfect indicators of exactly how old any bicycle might be. What frame and fork set characteristics fall under the microscope? Drop-out spacing front and back? There are many things to consider, when seeking to understand the detail, inherent in every vintage road bicycle frame and fork set.
In other words, though not all bicycles are represented with an on line serial number data base, some are. Raleigh, is the first that comes to mind but others are available.

First, a word of caution to anybody buying a machine, particularly if it does not have any documentation or proof of origin. If you are not satisfied then do not buy as mistakes can prove expensive later. If documentation is available then check the details against the machine. On most BSA’s the frame number is located in the following places. It is always stamped, raised numbers are casting part numbers. Up until it is rare for the engine and frame number to be identical and where the frame is shared by several models the codes start with the smallest model e.

Intended as a sporting machine capable of competing in virtually all disciplines, it was supported by a range of options that enabled the owner to tailor it to their needs..

Before then registrations were carried out by County Councils or Borough Councils, but Centralised Registration pulled all these records together onto a computerised system.

BSA B50 Bsa B50 is a four stroke cc single cylinder motorcycle. Made between History saw the beginning of a complete new engine/transmission design with the introduction of unit construction machine in place of the cc C
Edward Turner became head of the BSA automotive division and in BSA introduced the concept of unit construction, where the engine and gearbox were combined in one piece rather than as separate components. The camshaft was geared directly from the crankshaft with skew gears driving the oil pump and the contact breaker assembly mounted behind the cylinder via a shaft.
The alternator was to the left and the primary drive was via a duplex chain to a multi plate clutch. The four speed gearbox was at the rear of the vertically split crankcase. The frame was single loop with twin rails under the engine and pivoted fork rear suspension, and both wheels were 17 inch with full width cast iron hubs. An oil tank was under the seat on the right matched by a toolbox on the left. Between them was an ignition switch panel hiding the battery.
The headlamp was fitted in a nacelle which also housed the instruments and switches as was fashionable at the time. Deeply valanced mudguards were fitted to the standard model, making it look heavier than it actually was.

So this is the bike that he rode in most national trials in the UK from Another person working in the same department was Scott Ellis’s father Sep. And Scott was now a “BSA” works rider , he was also on a quest to build a lightweight bike with more ground clearance. Pat remembers seeing Scott’s frame in his fathers office one day, and also the comp-shops welder George welding brackets onto the frame.
Now this frame turned out to be the final one fitted to his works ride BOK C, first registered in January But as you see Pat’s bike was probably the one that inspired the others. We would love to know.
