    Default Military motorcycle

    I just bought this old bike.
    I placed it here in this forum, as it falls through the cracks a little and wanted to show it to you in its current configuration, as it will not be restored as a military bike. Paint is not original, but its retains some of the bits, that the army wanted on these bikes i.e. rear light with lid, which can be flipped down and up to cover or uncover most of the glass through which the light shine (for discreet ...and not very visible...night riding), tool box placed on the rear fender instead of under the bike and long military stand which was a stand asked for by the Army to support the bike better on soft ground than the standard stand would. Standard stand is retained. The military stand is the long strut visible going from below the seat and down in an angle.
    The bike was used by both the 'Allies' (Denmark) and the Germans, as several of these bikes went with the Germans to the Eastern Front. During the occupation of Denmark, the Germans 'persuaded' the danish state to let them have some of these.

    The bike was sold off at some point and has had both Norwegian and Swedish owners.

    Its a made in Denmark '52 Nimbus with a Hayabusa-killing, rip snorting, quarter mile tearing ....ahem...22bhp (good for cruising at 50-55mph).

    Over 12.000 of these were made between 1934 and 1960 and thousands still roam the streets of Denmark.

    Way ahead of you

    When I mentioned, that I wont restore it to the former military condition, I meant that I would remove the MIL stand and useless rear flip-down light, as I have no use for either.

    In regards to the current colour, its not original to the bike. At some point, someone slapped on a coat of non-descript bland colour. The bike has been ridden hard since 1952 and has the marks to prove it
    It is about to be stripped for a complete overhaul.

    As for a future paintjob, Im currently contemplating either RAL 1002 or RAL 8020.
