I have recently been browsing wikipedia and found some stats on the ninja 250R, but I'm not sure about one of them. Here they are:
---------------------------------------------------------
0-60 mph (0-100 km/h) 5.75s

1/4 mile 14.6 s @ 88 mph

Maximum speed 105 mph (169 km/h)

Max power 36 hp (27 kW) @ 11000 rpm, 26 hp (19 kW) @ rear wheel

Power / weight ratio +/- 0.13 kW/kg

Max Torque 18 ft.lbf (24 Nm) @ 10000 rpm, 14 ft.lbf (19 Nm) @ rear wheel

Fuel Efficiency 55-75 mpg US

As seen here: en.wikipedia.org/wiki/Kawasaki_Ninja_250R
---------------------------------------------------------
The two things in question are related and they are the 0-60 time and the 1/4mile time. It seems to me that the 0-60 on mine is a bit better than 5.75 sec and that the 1/4 mile would be just a little faster, but then again, I am no racing expert, but just a bit curious. Still not bad for a 250, I know a few guys with tricked out cars that are just barely getting into ninjette teritory! :D

Recent tests of the 250 (1st gen) come up with specs that are significantly slower than listed on that wikipedia page. And the 2nd gen is likely even a little slower than that (a little more weight, a little less horsepower). Only way to confirm your own bike's performance is to take it to a local drag strip and have some fun. Keep in mind that the speedometer on most ninjettes (and most motorcycles in general) is very optimistic, so when you're trying to clock a 0-60 time, you need to see at least 66 or 67 on the speedo before you're at a true 60 mph.

I want to bring dead threads back to life..as the pre gen tech is getting slow..i don't care if you jump off a cliff, or slip your clutch at 12k the on way this bikes hittin a true sixty that quick is if your hit by a tahoe going 80 as you launch

If the bike is geared correctly and you shift through the gears quickly that time is atainable.

i agree as long as that tahoe hits you square....and what would the correct gearing be?
with a 15 tooth front sproket and a 120 rear i can hit a true 60 at around 12.5k in third and 7 seconds is about right..my old lt1 camaro was a 5.5 or so to sixty car and this bike doesn't come close

My 08 would go 15.2 in the 1/4 and 0-60 under 7 sec with minor mods. With a small and good rider a first gen should be faster.

Nate, just because YOU can't do it on YOUR bike, does not mean the bike itself is not capable of it. I'll see about taking my bike to one of the test and tunes this weekend and do a few runs.

Those stats came from Kawasaki at one point. Knowing how small and light their testers probably are I could see it being close to those times. On my bike I'm like right on the bumpers of people with 14sec cars when we do small runs for fun. I'll try to get to the track this weekend and get some real numbers.

cool maybe YOU can do it

cool maybe YOU can do it

I'll sure try. :D

Just no need to down the ninjette as much as you did nate. You make it sound like it has a chainsaw motor for power. It out accelerates most cars on the road (except sports cars and the like). All I'm saying is it's not as slow as you are trying to make it out to be.

0-60 mph (0-100 km/h) 5.75s

1/4 mile 14.6 s @ 88 mph

Maximum speed 105 mph (169 km/h)

Max power 36 hp (27 kW) @ 11000 rpm, 26 hp (19 kW) @ rear wheel

Power / weight ratio +/- 0.13 kW/kg

Max Torque 18 ft.lbf (24 Nm) @ 10000 rpm, 14 ft.lbf (19 Nm) @ rear wheel

Fuel Efficiency 55-75 mpg US

The max power in Europe is quoted as 24Kw 33 hp as this fits in with the licensing stages i.e. any size motor you want but no more than 25Kw

I'll sure try. :D

Take me with a grain of salt if you will...i luv my lil ninja but it seems to me a lot of people talk it up to be something it's not..
there's a big difference between say 5.5sec to 60 and lets say seven flat
like Lt1 camaro vs. 3.8l camaro
I don't care how good a driver you put in the 6 banger camaro or how skilled they are at launching it they are not gonna will it into a z28's realm

This is true nate and you won't get a vehicle to go more then what it was built for. However, if a manufacturer says they got it to do this, then it "should" be possible. Can we as common folk duplicate it? Most likely not. For all we know these numbers came straight from a dyno where things like weight, temp, wind resistance, and track conditions don't come into play. If these numbers did indeed come straight from a dyno then it's totally believable.

I will try to get to the track this weekend and do a few runs. Mind you, I'm not an expert drag racer on a bike, and the track I can go to is not the best (actually the track kinda scares me cause of how little traction alot of people get on it :ohno:). I'll post what I get and if I can find someone with a scanner I'll try to get the actual slip posted on here.

where's a manufacturer rating specing this bike at those speeds? those numbers came from a wiki? I could change it to 0-60 in 2.3 seconds and some day people would argue the 250 can smoke a busa....

take people and there claims with a grain o salt:)
good luck at the track..let's see your time slips!!!

here's my ninja hittin 15.2 racer x lets see yours
LOL...

Here's a little bit of research. It's fairly informal so there are inconsistencies like what type of Dyno the test was run on and what exactly was modified on the bike but I think it's better than nothing.
