my2ks2k - Insurance must be a lot cheaper there.

To all others - The reason your lap times on a bike are slower is because you can push a car to its limits much more than a bike. Pushing a bike to its limits requires late, hard braking, LOTS of corner speed, a knee down, and early acceleration. You should accelerate so early that both tires end up on the bricks at the outside of the corner. If you aren't doing those things, you aren't coming close to the full potential of the bike. 90% of the people that ride sport bikes either can't or won't brake late and put a knee down. It takes a lot more practice to be able to run 100% on a bike. Nicky Hayden has been riding since he could walk. Most of us haven't. Put Hayden on a CBR1000rr and anybody on this forum in an S2k with r comps and coilovers and see who has faster lap times.

 

Or find anyone that can run faster than a 1:22 at Laguna since that's his best time at that track on a bike.

Oh wait that's motogp so how about Jamie Hackings 1:27.1 from last years Superstock class race at Laguna.

 

I used to roadrace motorcycles and do frequent trackdays. My best clocked time was 1.56 on an Aprilia Mille Factory, and I think I've beat that on a GSXR 750. I was told I was doing 2-high teens in my old S2000 @ TWS in Dec., which is a huge difference.

I quit street riding, though, b/c of the added danger and steadily increasing police vigilance/traffic around ere. Also, my then-gf/now wife enjoys Hill Country drives, so that's something we can enjoy together vs. me being gone all day. The S2000 is largely responsible for me giving up street bikes, since it's so motorcycle-like in many ways. A car is much more comfy, I'll take A/C and shorts over leathers anyday (my perspective might change if I lived in a more moderate climate). I prefer motorcycle shifing too, esp. when it puts you right in the powerband for a big wheelie!

IMO, 2 wheels are way more fun @ the track, but I'll stick w/ my Cayman S for street running. I still get my motorcycle fix w/ 2 KTM dirtbikes - an '06 450 XC and an '07 300 XC-W. They're about as much fun as you can have w/ your clothes on!

To even consider F1 times is absurd. Production bikes are much, much closer in performance to pro race bikes than production cars are to F1.

 

IMO both riding and driving are tremendous fun.
I would say it is much easier to be quick in a car than on a bike. All things being equal cars are faster on a winding road. with this in mind I have to say it is much more rewarding and fun to ride a motorcycle at its limits compared to driving a car.
Not everyone can ride a bike quickly while alot of people can drive a car quickly.
Just an opinion from my experience with bikes and cars.
Here is an interesting video. CIVIC VS CBR
