i'll second that! the e55 sure fulfills my need for speed. although i still look forward to riding, i don't crave it like i used to.

I challenge any of you to beat my bike... it traps 18 mph in the quarter ...

Somehow, I actually think that may be yours!!

Only referring to acceleration once out of turn 4, not the handling limits of the car. After apexing at the last cone, I was hitting full throttle, and accelerating from roughly 90~140. On the bike, I exit the infield after the end of turn 4 at maybe 80 and can hit 170 by about start/finish. We run a combination of the infield track, and part of the banking on the bikes. Good times.

I get what you are saying and yes it is relevent to the topic. That exact scenario is where I meant that I felt the E would do well against a 600. So, in that sense we are at least on the same page, even if we do disagree on the outcome. You got nuts, my friend. It is amazing how bikes raise your threshold for thrill and precision. It is hard to explain but I was always under way more control in the car after a few days of hard riding. It really teaches you to pay attention.

As you will see, 600 series bikes are DAMN fast these days. Up until 130 or so they are very close to liters.

Bottom line is that with a good rider, a bike is no match for most 4 wheel vehicles. Power to weight ratio is the key here.

Aside from speed, handling is another story when comparing 2 wheel sport bikes to their 4 wheel counter parts.

Bikes are fun

Just to set the record straight...unless your car is heavily modded theres very few stock cars that will beat any modern 600 bike. I own a GSX-R1000 06 and wanted to comment about those 1000cc stats. They are all wrong. These bikes are 9 second bikes stock not 10. Their numbers are fudged. Most all sites have a GSXR1000 06 and ZX10 06 doing 9.6 - 9.7ish 1/4 stock. Yeah you might beat a 600 from a roll-on but 600 are geared low. My GSXR1000 does over 100 in first gear, you wont beat it at a stand still or roll-on. These bikes do 0 to 60 in 3 seconds or less. Thats your answer in itself. I know you love your cars as most do our bikes but facts are facts. Lots of people talking out of their @$$ and don't know any facts. Hardware to hardware your car will lose. Any modern bike you beat...you beat the rider 99% of the time. Sweet rides you guys got.

Also to chime in on starter bikes...learn on a smaller bike not the 750's and 1000's. So what you loose money...better to loose money than your life. 600's are not great starter bikes no matter what anyone has to say. Anything 500cc and below are. Plus they are cheaper...learn on a old then buy new then you wont be loosing money. Pride is what gets you killed...but most rather look stupid laying in the road thinking the 1000cc stickers on their bike still makes them look l33t. I started on a 600 cc bike and didnt get the 1000 till i logged over 13000 miles. Take saftey course (MSF) for those thinking about getting one before you ride. Be safe.

4npower

i think that is pretty much what everyone is saying
i've found that to barely beat a STOCK 1000cc bike you need about 700whp and a 600cc about 550whp.

Gentlemen,

The power to weight card has been drawn many times in this discussion. However, you are forgetting one very important detail. Power means nothing if you can't get it to the ground. Consider the amount of rubber in contact with the road on any beefy AMG toy, and then consider what a bike puts down with a 1-2" wide contact patch. Let's look at the numbers in very simple terms.

2006 Yamaha R6S
123 hp (@ crank)
357lb dry (Call it 535lb w/fuel and small rider)
2" wide contact patch (hugely conservative)

2006 MB E55 AMG
469 hp (@ crank)
4087lb curb (4237 with driver equal weight to bike rider)
20" wide contact patch

Power to weight:
Bike: 4.35 lb/hp
E55: 9.03 lb/hp

Power vs. footprint
Bike: 61.5hp/inch
E55: 23.45hp/inch

The bike has much more power to be put though each unit of footprint available, IE: Far less traction available than the AMG. While I do still believe that a very competant rider in any injected 600 will lay waste to anyone in a stock E55, realize the the difference isn't as clean cut as power/weight. The ability to put the power to the ground has so much to do with performance in these high output machines we all love so much. And in the case of a bike, effective power transmission is directly proportional to the rider's "attachments" and experience.

Rider/driver has so much to do with who kills who. I've been racing 100cc and 125cc karts for years, and to this day I typically waste most 125cc shifter drivers in my 100cc HPV (single speed, centrifugal clutch). It's all driver. The 125 is too much machine for 95% of the people who drive them, as is a 600cc sportbike to 95% of it's riders. Put Rossi in a box stock R6 and watch him mushroom slap an E55 any day. Put me on the same bike, E55 wins every time.

This thread mostly refers to drag racing. Road racing is a totally different game, which could easily produce a thread twice as long as this one. As far as straight line acceleration is concerned, most modern sport bikes do not have any traction problems. Keeping the fron wheel on the ground is another issue.

k4lpcm

Akara1,

Good launch skills are a valid argument regardless of road or strip racing. Whether I'm on a grid or behind a tree, I need to know how to most effectively put the power to the ground. Ask any hardcore drag racer what the greatest advancements in the past 20 years have been, and the instant reply will be tires and clutch. Not horsepower.

I've had bikes break the rear wheel loose on me before the front wheel came up... it happens, and it's scary.

I wasn't disagreeing with the fact that a bike will take out an E55... just making sure that everybody puts it into perspective above and beyond just power-to-weight. Hell, the bike could very easily lose with improper gearing, regardless of any amount of power.

Anyways... bikes are cool, big mercs are cool. Bikes leave bigger scars :-) I'll take 4 wheels any day, regardless of speed potential.

stevebez

Shees ... I would have thought this was quite clear.

In a straight line forget it - the bike is waaay quicker - "even" a 600. Its a friggin' rocket. A K4 with NOS might just keep up to read its number plate.

In corners its very different. The car despite its weight is much more agile through corners due to traction AND lower centre of gravity. Bike is much worse. It has to deal with the gyrosopic effect of its wheels and high centre of gravity - yes its higher than a car. Not saying a E55 will run away from a bike through corners but will have a big advantage.

There was a episode on either Fifth Gear here in the UK where they took a big bad bike (GSXR1000) and a guy who could really ride it - power sliding out of corners and trail braking into corners... just to show he could ride and he knew how to ride!!! They raced them around a track against Westfield XTR4. The Westfield won by some margin. The bikes advantage on the straights could not over come the deficit in the corners...

Ill try find the video link.

Edit: Could not find teh video but here is a list of their laptimes... That GSXR is quickkkkkk!

OK : Found the video - had to buy it - and not allowed to post it anywhere (c) ... anyone who wants it - Ill mail it to them if they want. Just PM your email address.

I say at a roll the E55 has a great shot against a bike from say 40 to 100???

awiner

I'd disagree. Upwards until around 130, the E55 would not be able to start closing.

This is where the areodynamics of a bike start to show how bad they are.

stevebez

No chance even with K4. Against a GSXR1000, NOS wont be enuf either.

People that have never ridden super bikes, especially super bike from the past 3 years or so don't really understand how intoxingly quick and violent they are.

Compared to cars it is a TOTALLY different world.

On the current crop of super bikes you better be holding on and tucked tight when you grab a handful of throttle in a low gear, because it's a lot like riding a bucking bronco and a missile at the same time.

Even since getting into bikes, cars just havent quite gotten me all excited like they used to.

I ran a McLaren SLR down PCH a month ago from a 40 Mph roll on. I was riding my 2005 Kawasaki Ninja ZX-6r (636cc).

The cicumstances were picture perfect. Cool overcast morning, with no traffic what so ever. We were West bound on a part of PCH that has no cross traffic on the West bound side.

Here is a SLR comming up quick that is willing to play a bit. Lurching forward to show me he wanted to have some fun.

The SLR was super quick, but didn't start to overtake me until 130+ ...

After 130, the SLR was neck and neck and if we didn't back off he would have over taken me at my next shift.

Wish I was on my MV F4-1000 that day

Out of curiosity, anybody ever take their E55 to Willow Springs (big track) and have some lap times for the purpose of comparison? Also, there was an episode of 5th gear where they ran a Ducati 999 against a Gallardo on a road course, and the Ducati came out just barely ahead.

lol...did you happen to look at the first post on the top of this page???

I put down a 1:36 1:37 in a RENNtech C32 but have never taken the E55 out. The E is just so massive I dont now how it will do. After lowering my E55 and giving it 2.5 degress of negative camber up front and 2 in the rear I think could put down a decent lap.

Oh I did manage a 1:38 in a E500 but that car was just to simple to drive. It actually did really well at the track. Most people came up and asked if it really was an E55. But the brakes on the E500 were toast after a day as were the tires.

The E55 would likely be a 1:36 high second car at the big track. The power would help but an E500 actually changes direction more quickly given the fact that its 200 lb less hefty.

The c32 has many go fast parts and totoally re-worked chassis. I tend to take turns 8 and 9 a bit easily as there is no need to test fate. If you want to run 8 flat out and fly in 9 a 1:34-1:35 is in the rang of reasonable.

Last trip out had an evo roll 8 times coming out of 1 and she had a neck injury from what I hear.

Akara1

Thanks for the numbers, good to know what these cars can do. How did she manage to roll 8 times? I'm assuming she went flat out into 2 and didnt let off at all? Thats crazy. Turns 8 & 9 are most deffinately the ***** turns. You should try it on a bike, haha, thats fun, lol. Fastest I ever went on my R6 is a 1:32, with consistent 1:33's. MY buddy Brant is now in the high 22's, to low 23's on his R6. Now thats scary.

vraa

For all I know they could just be random google searches.

CynCarvin32

Well the Evo came out of 1 with a heavy dose of oversteer and started going off on the outside of the short shoot between 1 and 2. She tried to play the hero and yanked the wheel back and the car whipped across the track in a sidways slide. As her car went back across the track from the outside to the inside she caught the bump (dirt rise just off the track) and it sent the car flipping over and over. I came through just after the wreck and I though she was in serious trouble but a friend talked to the starter a couple weeks later while instructing a drivetech event and he said she was fine now.

I tend to maintain 110-115 at the begining of 8 and get to about 120+ right before 9. I then slow to about 85 for the turn-in on 9 but I hit 90-95 by the time I hit the apex. I come out of 9 hard on the gas and normally hit 105 by the time I get to the pit road enterence. This gets the car up to say 135 ish coming into 1.

Should be said that without a Quaife LSD the car was much slower in 2,3,and 9. The E55 would just be a ball of tire smoke and hard to control drifts with its standard open diff.
