Some of the really quick ones could. Six Pack Super Bees would run in the 12s... but like anything else it takes expert tuning and driving. Stock 750s are supposed to run in the 12s, but not with me on it haha. And that's not even considering all the 'dealer' cars like Royal Bobcats, Yenkos, etc, or factory cars like the Max Wedges or Swiss Cheese Catalinas. Or if you want to get really ridiculous, the Ford Thunderbolt, good for low 11s right out of the box. However, -most- factory stock muscle cars intended for regular street use would not see low 13 second quarter mile times and thems that would were probably a bit temperamental about it."Men will never be free until Mark learns to do The Twist."

The mini ninja can't get much past 90 mph... A well sorted 850G can do 135 flat out. I would say that qualifies as faster.Originally posted by gs850cafe View Post
As I'm sure you know, faster and quicker are not the same. However I was informed by a friendly LEO that my 850 had a 0-60 time of just over 3 seconds (I received a ticket to prove it...) The internet tells me that the little ninja does it in 5.7
DISCLAIMER: Don't do 135 on the street!! It's super-uber-mega-ultra-illegal-to-the-enth-power and under no circumstances am I advising it!!!
Assuming your friends car is not set up for drag racing, and your GS is in top mechanical shape, I'd say you have a good chance of beating him.Comment

I dunno. But I'm thinkin the GS would need that extra topend just to catch up before either of em make it to the 8'thOriginally posted by 7981GS View Post

OK, my bad.
Don't see any Camaros on that list.Comment

Speaking of Camaros, if this kid(car owner) has, lets say, a 95 SS or Z28 in reasonable shape and he knows how to drive it the feller on the 850 might be in for some kinda rude awakening.Originally posted by tkent02 View Post

I had a 78 T/A that'd do 13 flat in street tires. It was NOT stock however.
If you can hook up without killing yourself your gonna have a shot. It's likely going to be easier for him to hook up cleanly unless you've got a lot of experience drag racing with a bike. It definitely takes skill to launch without blowing all your "umph" with a wheelie. A problem he's not likely to have.
I drove a 96? Camero SS or Z28 one (can't remember which) that had the LT motor in it with the 6sp tranny. They were damn fast. I was quite impressed and I've driven a lot of "very fast" cars. But what was even more amazing to me was how quick they stopped! Great brakes on that carComment

Corvettes and Cobras are not muscle cars. They are sports cars. Hemi's were so rare where I lived, in Orange County, they were virtually never seen. Most muscle cars I saw were 383 Road Runners and Chargers, 389 GTO's, etc. Not too many with the 4.1 rear ends, either. A GS850 would have taken them in a street race
A new '83 850G ran 12.72 at 103. I have a test of a '79, it was virtually the same. Barely a second quicker than a Fatboy.
If this Camaro is actually running low 13's every week, 1t is going to beat the GS850. I virtually never see any bikes equal what magazine testers get out of them.
As to a GS850 going 135 mph, only off a cliff. That is over 10000 RPM in top gear. It isn't happening.Last edited by 850 Combat; 03-07-2012, 10:57 AM.sigpic Too old, too many bikes, too many cars, too many things

850Combat,
I checked up on the maths a bit. Tried various 'top speed calculators,' this one seemed to be one of the better ones.
At 9500 rpm, the bike would be doing 135.2 mph. I'd say that falls into the "possible while not riding off a cliff" category. Provided your motor doesn't explode first.
Just for kicks 10000 rpm would have you doing a blistering 142mph!!
(yes I realize that these discount many factors, like wind, rider weight, temperature, traction, degree of slope etc, but under ideal conditions with a skinny guy hanging on, its possible)
//End Hijack
Regardless this is all irrelevant because no way is the bike getting to top speed in the 1/4 mile. The race all depends on whether your car driving friend is actually right, and knows what he's talking about running low 13's, or he is exaggerating.
Only way to find out is to hit the drag strip. Ohh and get someone to video tape it, it and share with the class!Comment

4460 rpm at 60 mph.
135 mph divided by 60 mph equals 2.25
2.25 times 4460 rpm equals 10035 rpm
That means 10035 rpm at 135 mph
Thanks for the correction, but I'm sticking to my story just the same.
What math did you use to figure it all out?
They red line at 9000 rpm, by the way, and they will not pull red line in top gear.sigpic Too old, too many bikes, too many cars, too many things

If you insist. Everyone not interested in long equations don't read this. I apologize.Originally posted by 850 Combat View Post
My math...
MPH = (RPM / Overall Ratio) x (Tire Circumference x .0009469)
(The absurdly small decimal at the end is the conversion factor to get your answer in mph)
In order for this equation to work we also need the equations for Overall Ration and Tire Circumference.
Overall Ratio = Primary Drive Ratio x Gear Ratio x Final Ratio
Overall Ratio= 1.775 x 0.961 x 3.090 = 5.270
Tire Circumference = (Width/25.4 x Aspect Ratio /100 + Rim Size/2 ) x 2PI
(25.4 being conversion factor from mm to inches)
Tire Circumference = (130/25.4 x .9 +17 /2) x 2(3.14) = 82.35 inches
Now we can plug these numbers back into the mph equation and see what happens.
MPH = (RPM / Overall Ratio) x (Tire Circumference x .0009469)
MPH = (9000/ 5.270) x (82.35 x .0009469)
MPH = 133.1 mph
Using your given redline of 9000, a GS850G could mathematically achieve 133 mph.
However since 135 mph seems to be the magic number here, what RPM would be needed to achieve this? Using some Algebra to re-write the equation to solve for RPM we find that:
RPM = MPH x (1056 /Tire Circumference) x Overall Ration
(1056 being the appropriate conversion factor here)
RPM= 135 * (1056/82.35) * 5.270
RPM=9123
So therefore in order for a GS850G to achieve 135 miles per hour in ideal conditions you would only need to spin the engine a mere 123 rpm's past the redline.
Mathematically possible, and still no cliffs are needed. Given how robust the engine is I would say it could withstand this RPM for short durations, I don't suggest doing it all day.
To everyone who came here to read about a drag race for bragging rights I apologize again.

Try adding in the secondary reduction of 1.062 into your calculation then try it again. The number you are looking for is larger than 5.27Originally posted by Tim Tom View Post
