This guy kept wanting to race me and he kept telling me that his bike is faster than mines and his bike has more power and he would pull off the line faster then me. So I say let's take it to the track. But, I don't know much about dirt bikes I haven't riden one and I don't know anyone but this guy who has one. So is it true is a street legal 125 dirt bike faster then a zx 6r. I know it's all about the rider and I'm a pretty fair rider but with this dirtbike being so light and powerful (as he claims) I hope it doesn't eat my little Kawi for breakfast plus I have 100 bucks on the line so can anybody give me any advice
Can a 125 dirt bike beat a 2002 zx 6r !!!

"being so light and powerful"
Dude, that describes your bike!! Unless he has done some engine work you should kill him in the 1/8 and 1/4 mile.
It really is all about the rider though. If you sit there and spin the tires at the launch you're not going anywhere

He might be able to keep up for a second or two, after that its over. Keep in mind your bike will likely go faster in first gear, than his bike will in 6th. Dirt bikes have close-ratio gearing, where as realtively speaking your bike is geared much taller.

The 125 doesn't have a chance in hell unless you stall it off the line and even then you should be able to catch him and pass him. By the time you go to shift into 3rd he will be staring at your ass end, probably even before then.

no, he shouldnt stand a chance. i rode a cr125 for quite some time and top speed was only like 70 or so mph. being very generious lets say 100mph. 600ss's should trap about 120mph+ in the 1/4. so, given that you can ride halfway decent, you should beat him by a rather nice margin.
I've got many, many, many hours on a 125 dirtbike (yz, cr, kx, rm - you name it). No way in hell will it keep up with any 600 ss (well, I guess I should add that this is contingent on you being able to launch your bike)
Yes, they are quick, but nothing like your bike. It's all in the gearing.
1st gear is only good to about 20 mph because of the close ratio. What's yours go to in 1st? 50? 60? He'll have to have shifted 4-5 times by then.
First of all, the 125 will spin like crazy in 1st because of the knobby tire (I've raced mine on the street before
) & it will top out under 70 mph. He'll be in 5th gear & won't even be able to see you anymore you'll be so far ahead and you will only be in 2nd.

Yeah, all years. Again, it's the gearing. You can get them up to 90-95 with sprocket changes, but the fastest one I've ever seen could only hit 105, and that was with a modified gearbox and sprockets together, but stock they will only go about 85. Even that's too fast for backwoods riding, thoughIan said:

Make it even...start with your bike off and on the side stand....
My buddy has a CR 125..I was really suprised at how UNDERPOWERED they are...they don't "hit" no where near as hard as some 80's we rode growing up. :eek
Really they are designed to have the chit rung out of them......once they are tapped out they have alittle speed to them, but nothing like a 600SS.

Up to whatever the dirtbikes top speed is, it'll be a race. So if you want to win, make sure you pick a longer distance, like a qtr mile.
But, if you take gearing into account and limit the race to the top speed of say my 300KTM (~70) at 220# about 50-55 rwhp, that should be GSXR-1K power to weight ratio range.

Of course, you realize if he beats you for one or two feet, he will still be claiming victory and saying that the rest doesn't count. I had a guy in a 4wd 4cyl toyota that wanted to race my old 77 camaro (built 350). He said that it would smoke me from 0 to 10mph in 4wheel low first gear only, my response was: who in the hell cares about going 10mph? Besides, I could smoke the tires up to about 50mph. That guy wouldn't leave me alone for about a year.
No . . . it won't be a race. It will be a killing (by the 600ss).Rsv1000R said:
It will crush the poor dirtbiker's idea that his bike is (was?) fast. He'll be wondering if it's actually running right.
And no . . . your Katoom will not even keep up with a 600ss let alone a 1k. It will loose just as quickly as the 125 will. It's all in the gearing. You have to hold it wide open & shift 4 times with a dirt bike to get to 70. On a ss, all you have to do is twist the throttle . . . bye bye dirtbike.
All this talk is just rambling . . . go race the kid & let us know what you find out.
Have you ridden a late model mx'er? While we disagree about the physics of power to weight ratios and gearing, a 2-stroke mx bike is fast, well everyone I've ridden anyways.Krabill said:
Like Gurney's Alligator, if your race was say for 60' times, I don't think a stock 600SS would stand a chance.
Thanks guys for the advice. I'm just going to race him and see what happens. Probably the thing has engine work or some bigger engine smashed in the inside of it I don't know but if I loss I'll get the money back my friend got interested and he's got a race that same day with a busa he's got a 12r drag bike and 250 aprilla race bike and slue of other bikes (11 if I counted right) he said if I lose he'll take his money with the aprilla right back from him so my money is safe. Probably we will both beat him and both make a killin
