Rudge Motorcycles

A Brief History of the Marque

Rudge Whitworth was formed in 1895 with the amalgamation of Rudge of Coventry and Whitworth of Birmingham, both bicycle companes. They began motorcycle manufacture in 1911 and went into liquidation in 1933. They continued trading under the auspices of The Gramophone Company (which later became HMV and then EMI) after moving to Middlesex, and ceased trading at the onset of WWII with the last machines being produced by Norman.

Rudge built Python engines which they supplied to numerous other manufacturers including Cotton, AJW, Rex Acme, Dunelt, HRD, Ardie, Zundapp, Alcyon, Follis, Monet Goyen, Moto Pedale, New Map, Lady, Povy, Escol, Mineur, Eysink, New Rapid, Universal, Aquila, BMP, Doglioli & Civardi, Galbusera, Ganna, Lynx, Meldi, Mello, Miller Balsamo, Moretti, Premoli, Simoncelli, Vittoria, Durandal, Eysink, Grindlay-Peerless, Styl'son and Imperia.

    Parts and technical inquiry
    Rudge Whitworth 1928 Four Valve

    I have begun the process of reassembling this wonderful old motorbike, which wqas taken apart by the previous owner about ten years ago. I have developed a number of questions, and have discovered that a few parts have either been lost or broken since the bike had been disassembled almost ten years ago. 1) Specifically, the carburetor has gone missing, and I will have to source a new one. I do have the throttle slide (which is badly worn), but no carburetor body, so I would like to source a replacement carburetor. Can you confirm whether Rudge used an Amal carburetor or another manufacturer, and can you please provide the proper model number and size?

    Please also confirm whether these are available either through the club or form other sources. 2) I will also require a new clock-spring for the kickstarted mechanism as the old one has broken. 3) Finally, I could use a new set of clutch plates, both fibre and steel. 4) I also have a number of questions about the assembly of the bike. Specifically, there are a number of bushes and/or friction washers (3081) or spacers on the bolts (3078, 3079 &3080) that go through the upper and lower shackles (3076 & 3077) which tie the two front fork girders together. I am having trouble determining which parts and the proper orientation for these friction washers and bushings. Can you possibly provide any diagram or guidance for this arrangement to assist me in the proper assembly./ Please also confirm if the friction washers and bushes are fibre, brass or steel. When I received the bike form John's estate, there were only three brass bushes on each of these bolts, which is unusual to have n odd number of bushes for this assembly. I would be extremely grateful for an advice or guidance which you might be able to provide to assist me in getting this old Rudge back on the road again.

    Thank you for your anticipated cooperation.

    Kind regards, Charles Boston, Massachusetts USA

    JAP engines
    Rudge Ulster
    Dear Sirs,
    I inherited a 1935 Rudge Ulster (or special) 500cc 4 valve single that I was informed was a JAP engine. Rudge is not in your list of motorcycle manufacturers using the JAP engines and I thought I should update your info.

    What brand and model year of this motorcycle
    Dear Sir,

    Could you please help to let me know what brand and model year of the motorcycle in the attached picture. I tried days to find the similar image on the internet but cannot find. This motorcycle was found in Vietnam during 1950s. Thanks a lot.
    ............

    There are some points which may help to recognize for example: the front suspension built by 2 small rods; the shape of exhaust pipe; One exhaust pipe on left side.

    Generally, It looks like an Italy Frera model 1938, but Frera usually build their exhaust pipe on right side, do you know any Frera model with exhaust pipe on the left side?
    ............
    Thanks you anyway, after research, I think (99%) this is a Rudge Special with modification of the exhaust pipe, it has 2 pipes but not 1 pipe as said in previous email. This picture was take in 1952, means, it is at least 13 years old, the pipe must be rusted and need to be repaired, that's why it looks different from the original Rudge Special.

    Thanks & regards,
    Sean Nguyen.

    The editor stated that suzuki were the first to produce a 750 single as a production run. This is incorrect. Rudge did a 750 starting in 1914.

    Elsewhere on the net there are images of a 1913 Rudge Multi 750cc Reg# SP-2788

    It is a very early 1914 but if you look, it is not a multi. Yes it is a 750.

    Rudge "Two port"
    I have photos taken at a race meeting at Boreham airfield in 1947[?]. I have been told two bikes are Rudge 2 port [Ulsters?]. Racing numbers 68 and 69. Anyone know when the races were held?
    Essex
    ...............

    Thanks for the info on EMU. I am tryuing to date the photos I took. One was of Jack Surtees [father of John] with his Vincent sidecar outfit.

    I love Australia [Queensland in particular where I have many good friends and rellies]. Was last in NSW and Qld in January this year! Some not so young rellies in Augusta WA still ride their bikes [Triumphs] around the place. I lived and worked in Brisbane in the late 50s [wish I still was with the state this country is in right now!] and at one time was secretary of the now defunct Queensland Motor Sporting Club. I took my G3LS Matchless out with me and did a few miles around the back roads of south Qld on it before coming home. Should have exported a 500 twin with me but was not aware of the situation before I left the Old Dart.

    Rudge Serial Numbers
    Rudge W.K. 6685
    I have recently come across an old notebook of my grandfathers with notes made of journeys on (and maintenance of) a Rudge motorcycle between June 1928 and October 1930. It seems he aquired the bike on the 28th of June 1928. I am not sure whether new or secondhand. W.K. 6685 appears to be a serial number - maybe the frame no.? Would anybody be able to tell me what model this would have been? Many thanks. John
    Bristol

      WK6685 is most likely the registration number. Ed.

    Valve lifter; headlight
    Rudge Whitworth Multi 1912 - 1915
    Having written (Aviation fiction) of the engine of an early Rudge being 'switched on', also of lights being switched, I was advised that the engine would be turned off by a valve lifter, and that lights would not be electric (switched on and off) but acetylene. Would be grateful for sketchy operation details. Pat Cunningham
    UK Derby

      Starting is probably by pushing the bike with the valve lifter engaged, then disengage when momentum gained. One lights the acetylene. Anyone care to elucidate? Ed.

    Rudge Bradshaw Special
    RBS 350 oil cooled
    Hi, I am in the process of getting an Rudge Bradshaw Special or RBS ready to compete in a historic hillclimb. The bike is alledgely a 250cc rudge frame with a 350cc oil cooled bradshaw engine. We have managed to get the thing running but we have no technical data to go on, do you know of anywhere we can go to get any technical data on this engine. It is fitted with a brass AMAL carb and a BTH mag and a three speed gearbox. Everything seems to work in a fashion but it runs very roughly, I really could do with some techno data to help me getting it running nicely again.
