Title: 1939 KM20 Deluxe
Post by: Gavey on 21 Feb, 2026, 09:15
Hi,
Can anyone give me the length of an early M20 field stand please? My M20 is fitted with the short pre war civilian prop stand that I really don't trust unless its on flat solid surfaces (although its nice to have it on the bike) and I thought a field stand would be a safer bet. Its the horizontally mounted stand with the pivot behind the saddle mount. I am also looking for the details of how the clip fits to the lifting handle/stay - or a complete stay if anyone has one.

Andy Tiernan did a review on a early war years WM20 with the field stand. You get a good look at it but unfortunately not how it clips on.  What it does show is the length and lean angle

Performance Engineering Services make field stand kits for the WM20, so may be able to help you. For some reason I can't post a quick link to the item on their website, so just type Field Stand into the search box.  HTH

All the stands I seen on various sites are the later longer versions, fitted from 42 I think? when pannier frames were introduced and the stand clamp and clip were repositioned. I've got a later stand but its too long to mount horizontally so before I estimate the amount I need to shorten it from photos I thought I'd ask if anyone had one they could measure so I can cut it to the exact length.
