"deLuxe" meant extra specification. These are the illustrations for the 1939 model year KM20.

OMG. Thankyou soo much for information. I hope someone has another photo for details. And is the serial number still only from KM? Is there anything that starts with WM?
my motorbike is engine coded
WM20. 20274.

Even if it's not the same. it's okay I will restore the bike to the De Luxe version

Engine 'WM20 20274' is from a 1940 military contract for 3,000 bikes....Contract number C6126....What is your frame number?..The pictures above show a civilian deluxe model...1939 military bikes, though based on the civilian deluxe models had a number of specification differences.....Ian

Re: I want More info for BSA M20 SIDE VALVE DE LUXE

is there any photo information of the motor unit approaching with Contract number C6126.???

I'm here just to get the machine only. without frame. and I'm planning to build that bike with a replica frame and stuff.

Re: I want More info for BSA M20 SIDE VALVE DE LUXE

I have a 1950 Deluxe. The only difference between a standard and deluxe for 1950 are the fuel tank and side stand.

Standard: painted tank and no side stand.

Deluxe: chrome fuel tank and a side stand.

On earlier year models there are a few other differences such as the silencer. But the bikes are mostly the same.

What do you mean by "build the bike with a replica frame"? If the replica frame is made in India, good luck with getting any part to fit the frame!

Re: I want More info for BSA M20 SIDE VALVE DE LUXE

DeLuxe grider frames have rubber mounted handle bars as well.
These are very rare
as others have said, basically a standard bike with more chrome
No internal differences to the engine , gear box or clutch
Some Deluxe machines had a different saddle as well ( wider with better springing ) but not sure of those were offerred on M20's

This bike in Egypt is from contract C6126, and the next bike is from the contract just before it and would be about the same. Ron

Re: I want More info for BSA M20 SIDE VALVE DE LUXE

yes. Coz I'm here only have the machine only. without frames.

and I'm having trouble finding original frames in Indonesia. I'm looking for an alternative on ebay. and mostly made in india. As for locally handmade, I'm worried about its strength

but for me it doesn't matter. because this is the art of building an old motorcycle in Indonesia.

if only it was easy i get materials to restore. maybe my motorcycle is done.
