    Hi, I realize I am several  years late to the party, but is  Motak Racing Sherpa 280  still in existence? I can't find them! Thanks

    It is a nicely built one off from a 198a in need of renovation.

  2. When looking through posts here in the Bultaco section for information on availability of a bearing kit to fit taper roller head bearings to the Bultaco Sherpa 199a I saw Pyramid parts mentioned as a supplier but when I contacted Pyramid they had no knowledge of the correct bearings or the part number. Presumably the taper roller conversion is a satisfactory improvement.

    Does anyone have any info on the bearings or a part number for Pyramid please?

  3. To the best of my knowledge all the Beta Rev 200 models were based on the Rev 3 250 engine fitted with a 125 con rod and sleeved down cylinder, the Evo may have been different though.

    For context, here we are (I can hear the groans from here), the modern pre65 machinery (apparently a bike articled in Classic Dirtbike)..  A very nice bike indeed but is it really a pre65 bike or is it a special?  And is it really no advantage at all over the original?  Does it really conform to the rules there are?  

    Well, it is almost uncanny how the silhouette matches the original machine pictured below it (in this case the on-road AJS 16MS (G3LS) to grab the short-stroke engine presumably) that it is presumably meant to be, you almost cannot see any difference at all!!... why would anyone want to ride the trick machine, it is so obvious!!

    Anyway, a picture paints a thousand words.  Again, it is not that trick machines should not be ridden and enjoyed just as much, they should.  It is that it would be nice to acknowledge that others would also like to ride the original bikes (at least original frame, engine, gearbox, forks, hubs, ignition) and have them distinguished in the rules and/or entry.

    The VMCC run numerous trials in several areas of the country where you could ride your bike, why not enter those?

    How about posting a photo of your bike so that we can see the differences between it and those pictured above.

    Hi putting a pre 65 bike together and have an AJS Stormer alloy wheel and hub, can this be used! I have seen a few bikes with what looks like this setup or is there something else similar. 

    Or what's the best setup to use, can't afford new alloy one's yet.

     

    Use the AJS wheels with their brake plates and alloy rims.

    Doc46,

    I had to google shuttleworth snap,  Made me smile.   Steve.

    Bisby in real life George Formby was a motorcycle enthusiast and I believe rode Norton, in the film he called himself George Shuttleworth which is why the bike he supposedly built was called the Shuttleworth Snap, I think it was built around a Triumph Model P. The race bikes doing the most winning around that time were the Marston Sunbeam so Sunbeam became Rainbow in the movie.

    Charlie on second look the forks are Triumph like so a pre-unit twin from Triumph it could well be?
