1934 Triumph 6/1 Pictures

Add Your Photos!

Triumph’s first parallel twin designed by Val Page and primarily intended for sidecar work (the engine is offset to the right in the frame).  Never a big seller, the 6/1 was dropped when Edward Turner took over in 1936 and was to be replaced by the 500cc Speed Twin.

  3. Hi
    Thank you for your answer,in fact it’s my brother who has this triumph but he has not computer and no internet also I write for him.For the wheel he needs only the center(sorry i do not find the word in french”moyeu”)and the oil tank is under the saddle.The best is if possible you give me a list of your pieces.If you need i can give you address(mail)or phone number but i don’t speak very well.I’ll give you more details for the pieces.
    Best regards jacques.

  4. Hello Jacques

    I’ve got a 6/1. It’s a bit scruffy but seems to be pretty original. I’m just riding it as it is- goes well. You can see some pics here; http://www.ukgser.com/forums/showthread.php?t=162551. (Posted by a friend. I don’t own a GS!).
    I have a rear wheel with brake plate if your brother wants it.
    My 6/1 is a 1936 model with foot gear change and no oil tank- the feed pipe runs straight from the sump to the pump. I believe that’s how it left the factory.
    Best Wishes

    • Hi Terry
      I was wondering if you have any I dear the value of a Triumph 6/1 ? 34 onwards would like to own one, one day just trying to get an I dear of price going to sale a triumph trophy trail and rob north trident would be looking to buy early triumph twin Kind regards steve

      • Steve,

        I don’t have much idea of the value of a 6/1 I’m afraid- I paid just under £8k for mine at auction three years ago- it was complete and pretty original, but a non-runner. Now that it’s up and running, I’d like to think it was worth a bit more, but don’t know.



        • Hi Terry

          Thanks for the e-mail, have been told by VMCC official expect to pay £8 / £10.500 for original running bike, one sold last year at VMCC West Kent international Rally sold for £4.500 running but not all original, bike was sold for restoration? and apparently very rough? He did say its like lots off old bikes its only worth what any one is willing to pay some like original and unrestored and others fully restored bikes but the price can be
          much the same

          Thanks for all your help, kind regards Steve

    • Terry,

      Are you interested in selling your Triumph?

      • Peter,

        I am thinking of selling the Triumph.

        I shall be riding it to the Classic Show at Shepton Mallet 8/9th Feb- if it’s not still raining heavily.

    Hi, I have a Triumph 1935 5/5 Sport in bits, can somebody help me find a gasket set for the engine please

  9. Mick,

    Best thing is to make your own; gasket material, hollow punch, bit of wood (end grain) sharp scissors and a pencil…..

  10. Hi there!

    Anybody interested in a 6/1 Triumph frame in goood condtition???
    May there is a front wheel hub and some footpegs also (I am not sure)

    Additonal to this, we have one or two Q.D. pre-unit hubs and a (somekind of strange looking to me) Pre unit late sryle gearbox, some pre unit footrest and may some pre unit brake lever (I still have to check)

    Kind Regards


    • Hi Mike
      Could you send to me some pics of your different parts.Do you buy all in a one batch or several?My address mail:jacques.orain0279@orange.fr
      thank you,best regards,jacques.

  11. If you have some Triumph 6/1 spare parts I may be interested in them.
    My email is javiergom72@mail.com

  12. Hi Mike-

    I could be interested. Please send me a few pics and some prices.



  13. G’Day all,
    I’ve just inherited a 6/1 basket case with broken crankcases in Australia. I’m trying to assess whether I can restore it but firstly would like to date it.
    Does anyone have engine and frame numbers listed by year model?
    What changes occurred during its short model run?

    • Hi Rocky

      What is the go? Are you going to restore it yourself? If not would you be willing to sell? I live in Perth W.A. where are you?

      Regards Richard

      • Hi Richard,
        Not sure yet, I have some more research to do yet and when I have all the bits together I’ll know better whether its something I can tackle.
        I’m also in Perth.
        Do you have a 6/1? Are you a member of the Vintage Motorcycle Club?

  14. Hi Rocky,

    Lucky you!

    Engine numbers are in the form 1.Vn.xxx where 1.V designates the engine type (6/1), n is the model year so should be 4,5,6- 1934- 36 and xxx is the unique engine number.

    One change I know of is that the pressurised oil tank/filter was not fitted to later models- there is a filter in the sump.

    I hope this helps.



    • Hi Terry, Thanks, I’ll check the engine number and oil filter when I get back to the workshop.
      Do you know when the hand change became foot change?, I seem to have both.

      • foot change became an option in 36 hand change and foot change require two different end covers on gearbox,footchange has a recessed section for the mechanism hand change is just plain what do you plan on using hand or foot change.

      • Hi Rocky,
        I am looking for a mechanism hand change to a foot change and if you don’t buy your mechanism could you do a drawing with all size to built this one,of course if you have time,many thanks.

  15. Johan Surkyn on July 2, 2016 @ 1:56 pm

    Hi all,

    Can anyone tell me whether the crankshaft has normal right hand treading or left hand? As the crankshaft is running backwards I was in doubt.


  16. Nearly finished a 1936 6/1 can’t seem to get oil pressure I have replaced oil pump relief valve ball and spring and seated the ball can’t seem to get oil up to oil cooler any suggestions?
    Cheers Noel
