    Important notes ..


    1. We realised that the last world record stoppie of 740 feet (225.5 metres), was probably the limit using a stock Buell XB9S all but changing the handlebars. So to go a greater distance would require extensively modifying a stock bike.
    Looking at the challenge scientifically, three factors were realised. We needed a greater take off speed. We needed a more aerodynamic shape in order to gain speed and stability. We needed to lighten the back end of the bike and add additional front forward ballast weight to make the bike lift easier.
    The Buell XB12R was chosen. It automatically has more top speed due to the bigger engine size and power output. It has a more aerodynamic fairing shape but more importantly, the fairing is frame mounted. This enables additional weight to be added to this area without effecting steering. So the bike will remain stable. This additional ballast weight positioned in the front fairing area has three purposes. (a) The buell has a very low centre of gravity which is ideal for track and road handling. However, for the purpose of this high speed stoppie, which is a very unnatural and extreme maneuvre, a relatively low centre of gravity is not necessarily required. So a front forward ballast weight will lift the centre of gravity forward and up. (b) A ballast weight will act as a counter balance weight against the weight of the rider. Thus creating a pendulum effect pivoting via the front wheel. (c) A ballast weight will help to prevent the bike from being lifted so high when the front brake is initially applied at high speed due to high air pressure and drag.

    The combination of the above has resulted in Craig Jones being capable of carrying an EXTRA front wheel stoppie distance of 133 feet (40.5 metres) over and above the existing world record set by himself.

    here is the buell
