And a BSA/Triumph conical rear hub, adapted to fit a Norton.
Very nice example of a featherbed Norton ES2 cafe racer,
with a Manx style tank and oil tank.
Very tidy indeed.

The curvature of the frame tubes around near the rear shocks.
The wideline had absolutely straight tubes there.

If you look at it from above, at the front of the seat the tubes should curve inwards a bit
- to give some space for your knees.
The wideline didn't give any space for your knees !

You might need the seat and tank off to see this, they can hide it to some extent.

Previous pic here of a slimline.
Note how the frame is narrower (slimmer) just in front of the seat area.

There are a few slightly different versions, to suit various models and years,
so yours may not be perfectly identical to this...

Ok, I understood the difference (slimline/wideline)
The bike is not perfectly restored but it gives it charm
It works well but not easy to regulate

Tell us the engine number.


It's a handsome bike. I don't like the slightly chopper-ish silencer though.

Frame - R = model year 1960, 88927 is in the range for 1960 as well.
If it is a roadgoing frame then it would be off a twin, slimline singles only started in 1961. Telltale for that is the top tube in front of the tappet adjuster cover in singles was crushed in by the factory to give clearance to remove that cover, for twins the tube remained round.
Engine - 41843 would be a late 1951 model. 79 x 100 = standard bore x stroke for a 500, ES2. From memory around 25hp if all is set up well. Allegedly capable of 80mph in standard trim - my wideline ES2 will sit happily on 60mph all day with some in reserve for overtaking.

A 1951 ES2 would have had an iron head, and fairly low compression.
And would be surprised if it gave as much as 25 hp - thats a later motor number ?
Can't quite tell if your head is iron painted silver, or a later alloy head ?

That's the air slide ("choke") fully on for cold starting, in case there's any doubt.
