Cotton Motorcycles

Cotton Motorcycle Logo

The marque was founded by Frank Willoughby Cotton in 1919, and in 1922 Stanley Woods began racing the machines at the TT, where, over the next five years he established Cotton as a force to be reckoned with. After the war, the firm changed ownership and continued to produce machines until the late 1950's.

Cotton used J.A.P., British-Anzani, Blackburne, Rudge Python (RP) and Villiers engines.

1972 Cotton Cavalier
I have a very recently acquired 72 Cotton with the Minarelli 170 motor. I'm quite curious to get hold of specs for the motor as well as where to track down spares. What other bikes used this motor. It would be ideal if I knew if a Fantic, for example, use the same motor when I'm on the hunt for parts. I'm quite excited about the new bike and this will be the first Cotton I've ever owned. Many Triumph, Norton, BSA, AJS and Ducati but never a Cotton.

    Have little data on the Minarelli 170 at present. The Cotton Owners Club has a forum - someone there may be able to answer your questions.

Cotton Motorcycle Patch
Hello. . . I found your website researching a NOS original Cotton Motorcycle Patch still in the plastic wrap manufactured by "franklin's of Coventry". I inherited some items when my Step father passed away and this is one of the items. He was an avid Motorcycle rider all his life and am told he owned a few Cottons.
I was curious if there is any value in NOS original Cotton Patches?
The patch is rectangular with a black background outside the Cotton Red / Gold Triangle.
Thanks in advance for any advice you can give me
Have a Wonderful Day

    Perhaps try advertising it on a collector site, catawiki for instance.

The bike is in need of major repair and before I purchase I was hoping you might offer some background or advice.

Hello, I've just come across your great site and thrilled to see so much about Cottons - they usually get overlooked! It is also pleasing to see how much international correspondence you have received. I am co-administrator of the Cotton Owners and Enthusiasts Club website and wonder if it would be possible to include a link to the new website as the old one has been overtaken by spam and is now dormant.
The new address is
If you're happy to include it that would be fantastic but if you have any queries/concerns please let me know. Many thanks.

Cotton Cobra 1967

Hello, We are trying to do a valuation on the estate of my recently-deceased father; his motorcycle collection includes a Cotton Cobra 1967. Apparently none of the bluebook-type valuers even admit that Cotton Motorcycles ever existed. Can you point me to a resource where I can get some idea of its value? Thank you, Mercy

Cotton bogwheeler trials bikes 1973 to 1976

I am not sure but if you would like some info from this era, we (Knobby Shop International) was the western us importer for motocycles. we had some influence on making the bike more competitive both from the factory's perspective and our own .we had a small team of competive riders and over 20 dealers. the last bikes we imported were the factory Trials 220cc Bogwheelers. They must be some of the rarest Cottons ever produced. Allen Greenwood of Knobby Shop International.


  • Would be keen to hear more, and if you have photos, adverts etc from the era that would be great!

Cotton 1941

Hi I have been trying to find out what model my cotton is and whereabouts the chassis number may be, I have the original green log book with the number written on it but unable to find it on the bike, any other info would be gratefully received. Matt
Matthew Triggs
Rochester United Kingdom

    If you have clear images of the machine it could be helpful. Let me know if you find the number, and its location.
    Serial Numbers: Engine Numbers and Frame Numbers

    Information is scant on this machine. However, there seems to be some doubt about the dating as one site writes, "Cotton suspended the manufacture of motorcycles during the World War II period, with the factory turned over to the manufacture of war goods." How did you come by the date of 1941 for your Cotton? Ed.
    Matthew: I have the original green registration book and the date is Sept 1941 if you read up it says that cotton produced a light weight bike with a villiers 9d engine just before the war so I assume it wasn't registered until later, I have been told this is a rare machine with only one other in UK.

Cotton Minarelli 170
I used to own back in 1972 a Cotton motorcycle prepared by the factory in Gloucester for the R.A.F team in the ISDT held on the Isle of Man in , I believe 1971, it`s english registration number was DJB6J which i was told was number 6 in the team of six bikes. Does this bike still exist ?? It was pale blue and had a fibreglass fuel tank/ seat tail unit, any info would be genuinely appreciated.

Cotton 250/325 Continental?
I have most of what I think is a Continental twin - the frame number is 'C85'
anyone got any ideas?
North East England
Will try and do a photo.
Frame is twin down tube and has the lifting handle on the rear nearside toprail. engine mounts look like 2T or 3T - theyhave lugswelded on. Two pairs of front forks, both Armstrong leading Link.
Front wheel is full-width alloy hub with air scoop.
Headlamp looks to be Miller - handlebars are slightly 'dropped' with integral lugs.
Tank is red/black and centre fairing and h.lamp fairing/trim is red. Frame is black.
Seat is just a seat - but looks correct.
Centre stand has a curved arch at bottom between the two legs.
Has a battery box cum Toolbox that goes behind centre fairing.
Hope this helps

History wanted
Cotton Arrow
Since 1975 I have owned a bike known as the Cotton Arrow. Reg no is 857 PMA and it is a Cotton Continental frame which was fitted with an Ariel Arrow engine with skimmed heads,wal phillips injectors, expansion chambers, Tomaselli levers/twist grip,hand made clip ons and rear sets with fibreglass racing seat and tank. Got the bike from a friends brother who bought it from someone in Wickford, Essex who had either built the bike or converted from circuit racer to cafe racer. Old green log book shows frame no as 61625. Bike has silver frame and red seat/tank with distinctive cotton arrow logo. (please see photo) It also had a half fairing as well which was red and silver.
Can anyone help with any history pre 1975 for this unique bike please? Thanks

I dismantled the bike in 1976 to rebuild it and it has been in bits ever since!. Unfortunately the engine, frame etc are buried at the back of the garage and it is probably a couple of days work to get to them. When I do finally unearth them I will let you have more pictures but I thought the tank was so distinctive that someone may recognise it.

I have tried posting this on lots of boards over the past 18 months with no success. The bike was very distinctive and VERY LOUD so someone must remember it.

I met the Arrow's builder when I went to his house to look at a pile of Velocette parts he wanted to sell which allegedly comprised enough parts to build a KSS, a KTT and a MAC but I didn't buy the Velo parts as it was too big a project.

I have an old log book but it only has my details in it as the original one was full and I had to get a replacement. I should try DVLA for old owners but haven't got around to doing it yet.

If anyone ever saw (or heard the bike) I am sure they would remember it as it was so distinctive. I have never seen another Ariel Arrow street racer and the Cotton frame is a pretty unusual choice. I don't think many were used on the circuits either so it should stick out like a sore thumb.

Anything which helps would be greatly appreciated.

Thanks Again Tony

Cotton / Rotax
Did Cotton make a motorcycle with a Rotax engine? If so which one and when?

Yes, 21 Rotax-engined Cotton roadracers were built from around 1976 to possibly as late as 1981. Mark Ty-Wharton wrote:
Ah - only racers and only 21 of them? I want a road registered bike with a Rotax engine
Thanks for your help

The Matchless brand was resurrected briefly in the 1980s, by Harris I think - that machine had a Rotax. The Aprilia Pegaso of course is Rotax powered, as is, I believe, the F650 BMW series.

Date: Fri, 1 Apr 2005
I have scanned in some documents that I have that should help you out. Probably the most important for getting spares is the names document as this lists the relevant people within the Cotton owners club here in the UK. For Minarelli spares then Paul Powell is your man. A few years ago I met the guy and he couldn't have been more helpful. He has pretty much the sole surviving spares for these engines in the world. I assume that you have the trials version as in the photo, mine is slightly different as it is the trail/enduro version. Same engine but with larger forks and different exhaust. Brand new versions of the forks can now be bought from Greeves motorcycles . I include a schematic
of the forks which gives a good idea of the general layout.

Hope this helps

Just to clarify, Paul Powell has spares for the 175cc engine only, not all Minarelli engines.
