1931 Ariel Square Four for Sale1931 Ariel Square Four for Sale, ULTRA ULTRA RARE 1931 Ariel Square Four 500cc overhead cam model. This machine comes with a current V5C and is on its original number which is transferrable. I imagine it is worth something, but I am not an expert. WO was issued to the Monmouthshire area in 1931. The bike is tax and MOT exempt at this age. This bike has been in the ownership of one family from new and is only on its third keeper. The bike is basically un-restored and runs like a watch, All original fittings, and everything works at it should. It has clearly had a new exhaust system though at some point. The engine numbers started at 101….this is engine number 220….so effectively the 119th ever built. Is this therefore the oldest unrestored square on Earth ? has anyone got an older one out there in original condition ????? If so….I would love to hear about it. The factory records have been checked and the engine and frame numbers correspond. This was one of five built in March 1931 and this one was despatched to Bowens Garage LTD in Monmouthsire. You will note that this machine carries the original dealers brass plates on both front and rear mudguards indicating again that these are the correct originals as fitted to the machine.

I can say that I have ridden the machine today around a large car park for several minutes and it performed well. This is not the same as a proper road test, but tells me that the clutch, gears, brakes etc all seem to be working alright. It is charging strongly, and revs freely. Even the original brass map light works. Wheels and rims look authentic. This is a four speed hand change model.

So….this is a rare opportunity to buy one of the worlds first super bikes. Possibly the oldest unrestored Square left on Earth. Note, this is the engine where the crankcases spilt horizontally, like the Japanese bikes do, what a pity they did not continue with this type of design. Oil is held in the engine in the same way and when I look at this machine…it truly is years ahead of its time.

All that said…..this is looking for that rare collector / rider who will appreciate what this actually is. The question of restoring it or not will be up to you. I would love to see this out at shows and actually being used. If you buy this….you are pretty much guaranteed not to meet another as authentic as this. I would look at taking early machines in exchange….but am happy with a straight sale. No credit cards or Paypal on a deal like this, cheque, bank transfer, bankers draft, switch card or £££££….all good. Viewing is vary much advised. Please call and ask for Frank on 020 8997 2421 or 07973 11 12 13 for an appointment.Email: fjk222@hotmail.com
