Is there a passenger seat that attaches to the rear mudguard of a WM20?
I do have the rear rack but have removed it temporarily. Is it the case that the rack has to be fitted in order to fit a rear seat/squab or can it be directly fitted to the mudguard?

It depends on the year of your M20...If you have the small rectangular rack (without bags) as fitted to early wartime bikes then there is no pillion seat fitted...

If you have the later rack, with the bags and carriers, then a pillion seat would have been fitted...

In that case, the (correct) seat is particular to the M20 and you do need to have the rear carrier fitted to use it....Ian

Thanks Ian. I think I've got that. I thought that might be the case. My bike has the later rack but does not have the pannier frames. I've had a quick look round on google images and I see the pillion seat you mean; seems to have a short length of extra mudguard as its base plate. The chances of finding one of those is pretty slim I guess?
However, as I've got the rack off at the moment, can I fit a generic pillion seat (an upholstered rectangular block) directly onto the mudguard? There seem to be several on eBay and there's also a Wassell sprung type pillion seat.

The only problem with that plan is that you will be drilling extra holes in your rear mudguard...though that may not bother you...

There is a very good replica of the M20 seat available which isn't cheap but is an excellent copy of this complex part...

Mail me off forum if you want more details...Ian

You're right Ian; drilling extra holes in the mudguard might not bother me. I was primarily concerned about the general profile of the underside of these foam block seats although there are several examples of this type on google images. The nicest is one on which the late rack is in place but the
curved front hoop has been removed and then refitted further back on the rack, thereby allowing more room for the seat block, which itself, is raised up slightly on about 1" risers, off the mudguard. Quite taken with that solution, I must say.

If I can work it out, here is a picture of the M20 with nice pillion seat solution;

This is a correct pillion seat for an M20. There was also a shorter version introduced a bit later in the war, after it was reported that some riders were hitting their arse bone on the front of the pillion whilst riding over bumps.

Here also is an official picture showing a 'Bum Pad' fitted. Again, very close to the riders saddle. Ron

I thought the problem with putting the seat and weight too far back was that it created " interesting" handling. The bum pad shown is nearly behind the wheel spindle.
