Complicated issue, lengthy explanation:
Firstly an early R1 is barely any quicker than a modern R6 so you have to look at the exact model year. E.g. My ZX6 is actually more powerful and a fair bit lighter than the early CBR1000R Fireblades. Most people with no knowledge of bikes just think every blue bike they see is an R1 and very fast...
Plenty of info on bike v cars. A lot of people make false assumptions.
Firstly my bike can carry a higher mid corner speed than my car but I would not dare on the public road because a biker has a far lower risk threshold for obvious reasons - huge consequences of making a mistake and more exposed to changes in grip levels from white lines and spillages etc.
A magazine recently tested an R6 and an Elise and found that the mid corner speed was actually the same. The bike loses out from turn-in to the apex and from the apex to the exit point. I.e. the transitions. In terms of braking the bike wasn't that much slower than the car. The bike has to brake a lot earlier because it is obviously travelling a sh*t load faster than the car at the end of the straight and this gives casual observers a false impression about the braking. The car though can brake hard to the apex and apply a lot more throttle from the apex.
Going back to transitions and braking points...when 0-100-0 tests are carried out the bikes usually own everything to 100 but then the top few fastest cars catch them under braking. It is not the braking where they pull back most of the time though but the transition point from where the bike comes off the throttle and builds up to 100% braking power. Even my 600 is floating the front wheel at 100mph so if you just slam on the front brake it will skid out from under you as the wheel isn't on the ground! So you have to roll off the throttle and gradually build braking pressure whilst the car driver just goes straight from throttle to 100% braking.
Evo did a track test where they put an M3 CSL and a Radical SR3 up against some bikes and the bikes won but you can choose tracks that suit different vehicles. You also have the Clarkson factor with his rigged tests. E.g. the one where the Porsche beats the bike around the track? Odd because if you send both vehicles around on their own in a time trial the bike will set a faster laptime... hmmm.... If you watch the Lambo v Ducati 5th Gear test you will see that everything I said is true and that in the middle of the hairpin and other turns the bike is travelling easily as fast. Obviously it can't corner as fast as 500kg trackday specials with downforce like that Jaguar JP1 I drove. My bike would own it on the straights but under cornering and braking the car is out of this world. I drove a Caterham, VX220 and Evo on the same day and don't believe for one minute that any of those three come close to that Jag for braking and cornering forces. Not even the Caterham is close.
A litre bike will have over 1000bhp per tonne versus 550bhp per tonne for a Veyron. I think the 0-100 time is similar - just over 5 seconds. The big difference is that the driver does not "drive" the Veyron. It has computer controlled four wheel drive with traction control and launch control so the driver does nothing. The bike has one wheel drive, no traction control, no launch control, no computer distributing power to the most grippy wheel, no stability control, no ABS...
A ZX10 can be had new for £6700 in the Autumn which of course means I can get one come the autumn! A Veyron may or may not take me at the lights but I can't say I have met one yet!!!!
