FN began production of bicycle frames in 1885, built their first complete bicycles in 1889 and began motorcycle production in 1900. These first machines were single-cylinder belt-driven bikes of 135cc, 1.25 hp with an automatic valve.
FN was building four cylinder motorcycles as early as 1904. These pioneer machines had a five bearing crankshaft and shaft drive, with pedal assist.
A British report on the Motor Cycle Show of 1924 reads, in part:
"There are four examples of the 8 h.p. four-cylinder F.N. shown, as well as a like number of the smaller, 2 1/2 h.p. single cylinder machine. Both types are shown as solo machines and as combinations. The 2 1/2 h.p. is shown with a special sports sidecar, and also with a super sports sidecar. It is worthy of note that balloon tyres are to be fitted as standard on the larger machine.
F. N. (England), Ltd., Kimberley Road, Willesden Lane, N.W. 6."
By 1924, FN had changed all models to chain final drive, and the single-cylinder machines were now "en bloc", the 348cc and 498cc engines available with both sidevalve and OHV heads.
The OHV versions of 1930 had very good performance, with tuned models competing at the Isle of Man TT. They also took speed records on at Arpajon and Montlhery racing venues with Brooklands racers Wal Handley and Dougal Marchant in the saddle. They took the Flying Mile world record at over 190 km/h - almost 120mph.
By the end of that year they held 33 world records.
FN ceased production of motorcycles at Herstal, Belgium, in 1963. They continued as a small-arms manufacturer and FN rifles were used by many armed forces including the Australian Army in the 1960s.

FN 750 4 cylinder 1923
I'm restoring this bike and its too hard to turn over - the piston rings are way too tight and have almost no flex in them. Any ideas?
Assuming the engine has not been dismantled, my first guess would be gummed rings. Try pouring diesel down the plugholes and leaving it for a day or three. Drain oil first, of course.
Thanks; this is what everyone is telling me but I checked for this and they do have the right clearance and do close up but they are incredibly stiff and even when removed from the piston you can hardly move them by hand. Apparently they were purchased 18 years ago so may not be the original grey cast iron type. Many thanks for your response. I’m an engineer but I’m really scratching my head over this.
Next step, new rings. https://www.google.com.au/search?q=vintage+motorcycle+piston+rings
Be interested to learn the result.

I have decided to sell the bike and have entered it with Bonhams for the next auction on the 18th November at The York show ground at Harrogate.
The bike was manufactured in small numbers and i have been informed by The FN owners club that it is the sole bike in the uk. Bonhams have also confirmed that on checking their records they have never auctioned this model before(ever)
The FN owners club have kindly posted the bike details on their website with pictures. You and your members can view, if interested them on the website shown below.Once on the website you just need to click the top left HOME icon and scroll down past the first post card picture and the details can be viewed by clicking red coloured text where necessary.
I am contacting you because i cannot find anywhere in the UK a club for FN's. If you have a FN marque specialist you may be kind enough to pass this info on for if any FN enthusiasts may be interested .

FN Year 1909 (?) 4 cylinder 748cc
I am trying to trace a FN m/cycle that was restored in the late a960's by my friend Harry Buchanan, former m/cycle racer and Irish Scrambles champion. It was a 1909 (?)4cylinder 748cc model and belonged to a Georgr Saintfield (?) who had a transport companythat operated between the UK and Belgium. It was passed to Harry as a collection of bits in a large box with the request to put it all together!
Harry restored it to perfectionfor Mr Saintfield and then rode it successfully in the Belgian Rallyabout 1966-1969 to prove that it would run.
The license plate then was H-4718.
Harry is now in his late seventies and would be very interested to know whatever became of the bike with which he was so involved at one time in his life.
If you should know anything at all about this machine, or can give me a clue as to how I might find out, I would be most pleased to hear from you at:

Early FN motorcycle
I have just aquired the remains of two early FN motorcycles.
2 engine casings, No 2013 and 2035 (both of these are four cylinders.
Frames 72113 and 41096.
Could these be dated, and is it possible to contact someone who has or knows something about these machines?
Thanks for the quick reply.
The bikes are about 800 kms away from here at the moment. Will be fetching them in about three weeks.
They are in a thousand pieces and it will take quite a while before I can get them (or it) together.
The one frame, No 40196 is too narrow to take the four cylinder casings - obviously earlier and perhaps from a single. This frame is good.
The other frame, No 72113 takes the four cylinder engine but it is in very bad shape. The engine which is complete and in reasonable condition was used to run a circular saw. Unfortunately, in order to remove the engine, the frame was cut up and some of it is missing. I will have to replace tubes and it would be imperative to measure up a good frame to make a jig for rebuilding the frame.
The engine is a side valve, so that makes it post 1913. This is confirmed by the fact that it has a three speed gearbox.
Gear shift is at the rear right side of the tank.
I'll e-mail you any other details as I discover them.

Good day fellow enthusiasts.
I hope you can help ! A friend of mine has just bought an FN motorcycle. As none of us are experts on this marque we hope that you can help identify it.
It is a single cylinder 500 cc ( we assume), twin port.
The engine number is 10118.
Two numbers on the frame have been found - The first I think is the casting number at 870819.
The second number is 9874.
The only items missing that are obvious at this stage are the Speedo and the front light internals such as reflector, globe holder etc.
What year would this be.
Where can we get a parts manual for the bike.
Both of us are really BMW fans but my friend bought the bike because it is so well made and still in pretty good condition.
We thus like to rebuild it back to original standard.
