    Default CBR1000RR is the fastest stock literbike!




    The first every stock liter bike to cross the 200mph barrier in land speed record racing? It’s not a 193bhp BMW S1000RR or 197bhp 2011 Kawasaki ZX-10R, it’s a humble 175bhp Honda CBR1000RR, ridden by a girl.

    On Monday, Leslie Porterfield reached a two-way average of 200.137mph on a Honda CBR1000RR in the FIM 1000 P-P class. That’s a stock motorcycle with a stock engine. Like all such records, it’ll be a little while before the run is ratified as an official world record.





    Rules for the production class read:

    A “production motorcycle class” is as “produced by a recognized
    manufacturer”, and the public must be able to purchase a minimum
    of 500 frames through retail dealers. Production class motorcycles
    shall not be modified from Original Equipment at time of
    manufacture. i.e., frame, forks, gas and oil tanks, seat, front and
    rear lighting, fenders, wheels, brakes, air intake box and
    (unmodified) exhaust system. They shall also contain the engine
    that they where originally produced with.

    All production class motorcycles shall have manufacturer
    documentation specific to that entry. Production class records are
    subject to review and will only be certified after comparison with
    the manufacturer‟s documentation to support the production design
    of the motorcycle.

    The following modifications will be acceptable:
    4. A. ACCEPTABLE REMOVALS
    Acceptable removals are the license plate frame and bracket, air
    cleaner element, and toolbox.

    4. B. CHAIN GUARD*
    A chain guard is mandatory on all exposed chains.

    4. C. FOOT PEGS
    Foot pegs must be original equipment. Remove rear foot pegs.

    26
    4. D. HANDLEBARS
    Handlebars are restricted to 15-inches above, 4-inches in front of
    original mount or 4-inches lower. All handlebars that mount to the
    original mount and meet the criteria in this section are acceptable.

    4. E. LIGHTING AND INSTRUMENTS*
    Headlamps, turn signal lenses, and tail lamp lenses shall be
    completely taped. If desired, remove non-integrated lamps and
    signals. See Chapter 2, paragraph 2.H.

    4. F. WHEEL AND TIRE
    If necessary to meet tire speed recommendations, use optional
    wheels. See Chapter 2, paragraphs 2.Q and 2.S.

    4. G. SIDE AND CENTER STANDS
    Prior to making run, secure side and center stands in the UP
    position with “Zip Ties” or Safety wire.

    4. H. WINDSHIELD, FAIRINGS, SIDE COVERS, AND
    SEATS
    Motorcycles originally factory equipped with a fairing and
    windshield, seat and side covers shall participate with original
    equipment. The fairings and windshield shall remain in original
    appearance (height, width and contour).

    Rules for the production engine read:

    12. A. PRODUCTION (P)
    Use the same engines (gasoline only) originally installed in the
    specific motorcycle frame at the time of production and ensure it
    meets the definition set in the „P‟ frame class (See Chapter 4).
    Original equipment (OEM) shall include cylinders, cases
    (crankcases), heads, and carburation or throttle body (stock venture
    size), kick-starter or electric starter. GASOLINE ONLY. Fuel not
    permitted in this class. See Chapter 2, paragraph 2.F.

    P engine class shall not run in A, APS or S frame classes

    Effective 2012: Displacement determines the class. OEM
    displacement specifications must remain stock.



    So yeah, that’s a completely stock motorcycle, as you could buy from a showroom right now. How’d Leslie and her team reach such a speed on a bike with an on-paper performance deficit? With so little modifications possible, they had to do it with tiny aerodynamic mods like taping over fairing gaps, while performance gains likely came from trial and error with sprocket sizes and tire pressures as well as taping up seams in the riders leathers (as evidenced by these photos) and minor alterations in rider position. In land speed record racing, where a hundredth of a mile per hour matters and the performance variables lay wholly with the machine’s engine performance and aerodynamics and not its rider’s ability, the fine tuning of such tiny variables as seams in leathers can make all the difference.

    This news is made relevant by the recent whoopsie with the 2012 Honda CBR1000RR. Apparently equipped with no significant performance upgrades, it has a fairly massive on-paper performance deficit to pretty much every other liter bike on the market. Will that matter for sales? Probably. Should it matter to you if you’re in the market? Well, it may be the least powerful liter bike, but it is the fastest. The previous record was held by a BMW S1000RR. It’s top speed at Bonneville last summer? A paltry 196.117mph.

    For a true base line reading, rider weight should be equalized, toss 100 lbs on the bike with her and then do a run, It's the fastest liter bike with a 110lb woman on it, or Dan, he complains like a woman.

    I kind of have to agree with ninja on this put her on the other production bikes and have her go full throttle.

    or Grab two of those same bikes and have two different people ride them her and an average guy (over 160-195) and see how they compete head to head

    I'm above average 230+gear. Stock 08 gsxr1000 max out at 181mph
    Its faster than a snail, but slower than a jet
