They took along a standard GSXR as well...looks at the times

Fastest: Race prepped Crescent GSXR, followed by Radical SR3 tracksport (essentially a racing car).  Then you have the standard GSXR bike, the 911 GT3, the Lambo Murcielago, and BMW M3 CSL.  So of the 'road spec' kit, the bikes faster than all the cars!

And think about it - A BMW M3 CSL is *a lot* quicker than a 328i, hence my scepticism about the Devil being faster than any superbike!
