The Honda VFR and the Augusta is the only bikes i can think of that has a Quad under the seat, if this was one, the smallest version was a 750cc ranging up to 1100cc, and they're quick, not to rain on ur parade but i think the Biker was going soft with passenger (As I Would b) and u ain't giving bikes the credit they deserve, a CBR 600 f1 will leave my evo for dead, the old ///M3 was arguably one of the fastest cars on the road once u hit 3rd gear and my m8 made me look silly on his GSXR 600, in all honesty i'd b pretty pissed off if sum1 sat on my tail whilst i had a pillion, poor show, think the biker woulda been the same not surprised to see a clio there, more like hacked off
