    Making a bit of progress with the Kawasaki F81M inspired racer. Drilled and plugged the cylinder stud holes and relocated them to suit the Suzuki cylinder. The spacer plates will be screwed and glued to the cases and the cylinder studs will be threaded through them as well as the cases. If a KTM250 can make 48 rwhp then with methanol/acetone blend I am hoping to do much the same.

    I hallucinate, I thought it was legend and that it was not true.
    14 years ago in a forum in my country, I read about it and that it had disappeared, since they had been stolen.
    I don't remember if they said I had injection or electronic traction control

    This image is from the draft of the answer about the information they gave about a YZM, you will see that it is from 2005 and what I put in was:
    "The only YZM of 2t that I know of aluminum are, those of Frenchman Jachy Vimond and Kurt Ljunqvist, who played the 500 World Cup of '87, the chassis was not deltabox but simple cradle unfolded at the height of the cylinder and lacked all those technological advances that count.

    It is strange that because they steal the prototypes they lose all the technology, because I thought that this was reflected before on paper, which accounts have not applied anything "


    They didn't put pictures like you and when you don't see things you don't believe them

    Ceci,
    Photos is from RACERS vol. 53. https://www.ebay.co.uk/itm/RACERS-Vo...UAAOSw4O9dxGrX
    On 1991 YZM 250 they use Al frame more familiar to XXI century frames , but in 1993 they revert to steel on YZM 250.

    Brilliant magazine, so much interesting small details in photos and Japanese language, with translator, gives even more interest. All issues with 2t racers very informative. Latest 54 vol. is first part about NR 500.
    https://www.ebay.co.uk/itm/NEW-RACER...QAAOSw9-RdneEb

    This is more about street 2t

    As far as i know YZM was used on a heap of Works MX bikes over many years. Just as YZR is.

    M might be Mx
    R might be Road.
    F as in YZF might be Four Stroke

    Not sure if they still assign OW numbers to MX bikes but they used to in the old days.


    Honda use RC as a prefix

    i thought i read the yzm 500 was only used two years on works bikes. sounds like only eight were ever made
