    Made six valves per head and twin sparx easy.

    Hideously expensive to manufacture...
    Go soothingly on the grease mud, as there lurks the skid demon

    Darn, it was on display on Boxing Day? Cr@p I missed so much....

    Chappy, next year, you can fix the bike yourself! (Where did that come from you may well ask... But he knows...)
    And here is a picture of the bike at Wanganui. Very nice to see one in the flesh, so to speak.

    16 valve per head unless I'm mistaken: each oval piston had eight valves. And two plugs.

    there is a decent write up on it in "V-Force" by Julian Ryder.

    Much as I hate to say it, probably one of the best looking road bikes built, along with the RC30.

    Shame it's a Honda and therefore gay as. But don't tell Steve I said that about his bike............

    He goes on to say the English had done work on square cylinders 25 years prior, and that testing of that idea was ongoing in research labs around the world. (As at 1992.)



    "Square cylinders?" That could require new nomenclature.

    I've been doing that wet weekend thing of looking at old motorbike magazines. Found this last weekend.

    hopefully it loads: our fancy copier thing at work does colour now. mmmmm colour.

    From the June 1992 Cycle World, Alan Cathcart's test of the NR750.

    Yeah was all about building within the rules of the day and trying to make a more competitive four stroke engine for racing. I am sure the rules would now outlaw anything but cylindrical "cylinders" closing that loop hole. The road going NR was a great looking bike and the VFR I have took some of its design cues from that so I'm not complaining. The $100k price tag for an NR versus around $18,500 when my VFR came along meant I didn't have a problem with not having even thought of buying an NR.

    In the end the 2 strokes have been killed from MotoGP anyway, so no need for such variations from the norm and besides the MotoGP rules are quite restrictive on design these days.
    Cheers
