Don't know who #100 is but I believe his bike is a Honda CBR1000. Those sand drag riders certainly have some balls.
I'm always blown away how they can run events like this in this day and age, within a semi-suburban area of Sydney, but I love it. At one stage the band was playing hard, the motard boys were "racing" in the carpark and the V8 drag bikes were going for it. The organisers must have plenty of clout within the council, EPA, etc to be able to pull this off each year.
