This is my former Ariel, A 557cc 1933 VA-3. It was fitted with a 600 VB barrel, so the piston stopped 3.5 mm (!!) before TDC due to the different stroke of a 557cc sidevalve. (95mm in stead of 102mm) The bike drove like a dream, and reached 90-100kmh with no problem at all...

As you said Paul tapered tubes on Ariel girders where from 1934 > onwards. The 250 looks like a bike which can be a nice one, if you spend enough…

Karol this is a great work! Very well done!! Hats off!!!
Best regards, Paul

Roger very good work and most interesting, hats off! What will happen when a lost,- or duplicated number turns up? Will it be adapted in case someone asks for a dating certificate?

Paul - Yes! It is a 1954 PRF frame, it is missing from the despatch books. There were 5,420 of these frames made and 1.8% are duplicated with about 4% of the numbers missing. I assume it exists, which would not be unusual for missing frames, do you have an engine number with it or in a previous lif...

The bike became road legal and got a license plate on the 13th of april 1954. All the other components like magneto, dynamo are stamped 1954. The same for the gearbox.

The gearbox reads this number! So this is a all original bike I assume?

Thats sound interesting Roger!
The engine reads: PB 1401

Any info on frame KS2294 ?

This one makes the ‘we sell classic bikes NG’ a bargain…
