    This is a photocopy from a old Aussie magazine . Stated the bloke finished it and got killed on a Honda on the Highway . The waywardness of the early Jap fours in comparison - you takes your choice . A Z wotsit flug its rider at the Sheene thingo .

    Generally someone with the patiance to assemble suchlike isnt so exciteable or wayward , perhaps .

    This has not got a featherbed frame and you need a MotoGP bike to beat it :

    The Cameron JAP engines are really quick, they are often put into Morgan 3wheelers used in Hill climbs and historic Racing, watching 3 wheeler Morgans racing on hill climbs is about as exciting as it gets. There probably will be some at the Presscott hillclimb Bike day next weekend. the Cameron JAP engines are not that standard, Boyer ignitions and twin plugged, running modern motorcycle tyres, gives them quite an advantage in Historic racing.

    Hokey smokes, thats also a Norton plunger frame.
    Lottsa horsepower would be interesting if pushed hard. (no damping on the back wheel)
    It is a road bike, we notice... So rather a neat special.

    Also not clear precisely what model of JAP that is. ?

    For the Greg Sommerton version

    Also has links to a video or two of the engine working out in a speedway sidecar outfit against jap 4 competition.
    In there somewhere is the replica-ish of a Norton works 4ls front brake which outraged a few on here a day or two back.

    I love the look of that, however that is about all. I can imagine what it is like to ride fast on it. That motor in a Mk3 Seeley frame would not be all bad - you'd be able to get the weight well forward. I still believe the best motor to fit into a featherbed frame is the Manx. A 650/750 Triton can almost get there, however I would not attempt fitting the 880 JAP or Vincent motor. Even with a Triton you can find yourself going very quickly and have immense feelings of insecurity. I suggest that a lot about motorcycle racing lies in the bike creating rider confidence.

    in a current in Aus. issue of ' Octane ' magazine , theres a cyclecar - useing this type ANZAI crank case ( 2 litre ) with Wright Cyclone or some such cylinders & heads , for 3.7 Litre . :p

    [​IMG]

    The 1925 Anzai V-Max. :D " Mighty Anzani 2000cc v-twin engine for the cycle pacer - chain-drive casting is for the magneto " " designed by Léon Vauthier for bringing racing cyclist up to speed; 120kp/h in 1925! "

    Youd probably need the early wideline , to clear the cylinders . And a concrete block rather than a brick , for brakes . :mrgreen: Think its 1914 actually , the engine . ?

    or the 1928 2.4 litre . http://www.yesterdays.nl/anzani-pacing- ... -1335.html

    2 litre again http://www.bikermetric.com/vintage-bike ... race-bike/

    I saw a TV coverage of the first time Wayne Gardner rode a manx Norton. He rode up on the bike and got off almost crying and said 'I never knew what they were riding'. I gave my son a DVD of videos about racing Bentlys that I'd downloaded and he said 'they were only doing about 115 MPH'. I think many people miss the point about speed in the old days. It is easy to look at that stuff in a scornful way and believe that the speeds they were doing was not fast. I think if you were riding that 2 litre motor pace bike at it's max capability, you'd be shitting. As for the Bently, I think sometime that I'm going to have to pay for a fast ride in one, it could be a real hoot.

    Going slightly OT, for which I'm sorry. Aco mentioned Bentleys, presuming we are talking about "proper" WO Bentleys, before RR took them over.
    When I lived in Southampton I regularly used to see a real 3.0 litre and it looked huge alongside the cars of the day, it was 1961 to 64. Well one day I was on foot, one foot, as I had a leg in plaster, waiting to cross the road which was a 4 lane road out of town. There was a gap in the traffic, me and my crutches scooted 1/2 way across, then I saw matey in his 3.0 litre, coming towards me in the outside lane overtaking some stuff on the inside. I reckon he was about 2 feet away from me when he went by. Going by the other traffic he was doing 45/50 mph. It sounded like it was idling, revving soooo slowly, and the exhaust noise was fantastic, not loud at all, it sounded like rattling a big stick around inside a metal rubbish bin. I'd love to see and hear one going quickly, no wonder Ettore Bugatti described them as "...the fastest lorries in the world"!
    cheers

    Some of the videos of the Bentleys on Brooklands look really scary. Apparently they were set up for the banked circuit, and were more difficult to drive on level roads. It must have been impressive when guys like Tim Birken had them and the nobs used to bet on them.
