These debates have gone on for a while and most practical tests show bikes are quicker.
The Kawazaki ZZR1400 beat all-comers at a standard car drag race for one of the car magazines, against the likes of Porsches, Ferraris etc.
A Ducati was tested around a track against a Gallardo for Fifth Gear with the Ducati winning (as well as costing a huge fraction of the price).
Having tried both, I would have thought bike are quicker due to much lower weight, better power to weight ratios and mental acceleration.
And I know none of the SIDC lot could keep with JimmyMc when he was flying round the Mountain on his GSXR1000.
Hope you're all had a great Christmas and have a fantastic New Year.
Stay safe on the roads.
