Roebling Rd, Road Atlanta, etc... 951 vs. Suzuki GSX-R who would turn the faster lap times? whaddya think?

Gixer 750 is pretty tough...as are all the new 750s.

Well my R1 spanks my 944 any day. And my buddies GSXR 750 runs pretty close to my R1.

R1 is probably one of the meanest new sport bikes out there...it's 750 cc's will kill most liter bikes. The hiabusa (sp?) is a mean ass bike, though. I think it runs high 8's/low 9's stock. I just went shopping for bikes yesterday with a guy I work with, and I was impressed by much of what I saw. The ducati 748's are as slow as most 600's, but handle very good, and the 996 is a good way to spend $20000+ dollars. The R1's we saw were very nice...unfortunately they don't let you test drive new bikes.

The R1 is a liter bike. The 'Busa is very fast but also weighs quite a bit more than the R1. The new king of the hill for supersports is the Suzuki GSXR1000. ~15 lbs. more than their 750 with 150 hp at the rear wheel!

I'm sure a 951 is faster around the track though....

This isn't even fair.. you would have to find a race car to even begin comparing to a modern showroom stock sport bike.

comparing a bike to a car is like comparing a rocketship to an ultralight....(as far as speed is concerned)with an experienced rider that bike will kick the ****e outta the 951....but hey you still have a chance to live in the event of a highspeed crash right?

Sarcasm is lost on you guys....of course a modern sport bike, be it a 600 or a liter bike, will smoke virtually any road car on a track....even with a pilot with average skills.

Im fortunate to live 15 minutes from Roebling Rd. Having raced Superbike/Supersport for the past two years, my best lap times are in the low 1:18's The SCCA record for a 951 at the track is a 1:24.

Im not that fast though, cause I have a few friends who run the track in 1:14 DAMN!

Having two contact patches roughly the size of a pack of cigarettes is a disadvantage, but the power to weight ratio and low center of gravity (hangin' off) make up for it. Then again, I have thrown it away at 100+ mph twice this year, and got banged up pretty good the last time... broken collar bone and some mangled feet. So I am done for the year, I bought the 951 to keep me busy wrenching on something.

I used to have a moped

Top gear which is an English motoring program ran a test about two years ago between an R1 and 4 wheel drive carrera around Truxton circuit, the bike rider was Neil MacKenzie who was at that time the British Superbike champion, car driver was Kelvin Burt who was a fairly good touring car driver, the result of a one lap race from a standing start was that the car won by 1.5 seconds.

A 500cc GP bike which are the fastest kind of bikes bar none will get killed by an F1 car around the same track

I think it really depends on what kind of race track we are talking about. The big bike(over 600) will have a much faster pick up from 0 mph to maybe 80 mph. And bike can also corner faster than 951(virtually any 4 wheels..) in a lower speed turn. Yet, if the track has a long straight lane, the 951 will defintely beat the big bike..especially when the speed goes over 100~120 mph.

Conclusion: 951 can be faster and more stable on the higher speed(over 100mph). While the big bike starts and stops faster before 100 mph. It really makes no sense to compare track time between a big bike and a sports car.

Proven fact: the aerodynamics of motorcycle are REALLY bad compared to a car. Even bikes that spend alot time in a wind tunnel, and even fully tucked in. I think I read this in one of either Kevin Camroon's or Gordon Jennings articles. Maybe that would explain any advatage a car would have at higher speed.

Granted its comparing apples to oranges, I just thought about it since I live so close to the track. There was a post in here about an F1 car being the fastest, of course, its multi million dollars worth of technology.

we buy our Suzukis in the crate for $8000 from the factory, and I just spent $6000 on my 951, since both will see this track I thought id get your guys thoughts. The one post about the bike being slower on the 100mph+ parts of the course is wrong though. We hit 160+ at Road Atlanta and 173 at Daytona. Granted a specially prepared race car will always win over a motorcycle due to the amount of traction. I just wanted to stir the pot i bit.

Macabre · 08-02-2001, 07:08 PM

timsirk: you're right that they have a lot of drag, especially with a rider, but they also have an extremely small frontal area compared to nearly any street car and most full-bodied race cars. That's how a 100hp 600cc can get up to 160mph which a 217hp 951 can't even do.

The nearly nill drivetrain losses don't hurt either..

true...but remember a 951 is a little heavier than a sportbike. these estimates are rough, but

100hp/400lb??=0.25 hp/lb
217hp/2800lb= 0.08 hp/lb

i'm definately not trying to say that a bike has a bigger frontal area...just that a car's frontal area is more efficent. its kinda tough to cover that front tire and still keep it practical, even for the track.

i bet if you had a 951 that had
0.25 hp/lb * 2800lb= 700 hp
it would go WAY faster than 160mph!!

just some food for though.

Guys.... I have a dead stock 951 that will do 165 or so... of course that's by the speedo..but it's close...
