1939 Excelsior Manxman 250cc Racer Pictures

Add Your Photos!

The 250cc works engine i belive this was one of only seven works engines built for the 1939 tt that didnt get raced, i purchased this machine in 1953 which by then the engine was mounted in a norton frame.

the engines crank case was all electron and had hair pin valve springs, an all ally conrod which run straight on the crank pin (no bearing).

Would like to know if anyone has any further information or whereabouts on this machine.

    Hi,This bike was once owned by Norman Webb of New Malden and used in the 1951 lightweight TT. The petrol tank was a KTT MK 7 then and the chassis was a Manx, in your photograph it still looks like the KTT lined and badged Excelsior?
    As you say the engine has electron casings. There is a photo of the bike in 1951 in the new book, Excelsior The Racing Years, also a photograph of the plain bearing conrod that you mention.Do you have the engine number? I may have a record of this.

      Thank you for the information. It was a very long time ago when I owned the bike but if my memory serves me correctly the engine number was something like TT04.

      If you do have or can find any further information on the whereabouts or history of this bike I would very much appreciate it if you could send this on or post the details on this site.

      Sorry for the late response but I am getting old and forgetful so don’t log on too often.

    Hi there,

    This is very much like one I saw in a motor museum in Alford, Aberdeenshire. some years ago
    The engine had been fitted into a Manx Norton frame.
    Please let me know if it is the same Machine

      I am not sure whether this would be the same bike but I do remember that it was a Norton frame just before the featherbed frame was released to the market. The problem with the Norton frame was the weight as the 250 engine needed something a little lighter.
