These are figures from a recent test between the R25 and the Ninja 250 at Sentul Race Track in Indonesia. I'm fully expecting the R3 to carry a similar advantage over the Ninja 300 in Europe/North America.

YZF R25

Maximum power on the dyno 32.23 [email protected]
Maximum torque 20.17 [email protected]
0-60 km / h in 2.89 seconds
0-100 meters 6.14 seconds
0-201 meters 9.61 seconds
Best time: 1 minute 59.94 seconds
Top speed: 172 km / h

Ninja 250 FI

Maximum power on the dyno 28.16 [email protected]
Maximum torque 18.91 [email protected]
0-60 km / h in 3.08 seconds
0-100 meters 6.27 seconds
0-201 meters 9.74 seconds
Best time: 2 minutes 3.62 seconds
Top speed: 165 km / h

great stats.
as expected with everything else about the r3, for this it shouldn't be too far off from the r25.

Looks like the R25 beats the Ninja 250 on basically all counts. Do you think there are any other aspects of the Ninja 250 that would point to the Ninja being a better bike, or is the Yamaha just running away with this?

i think the r25 will make it really competitive and a lot of guys favor yamaha so i can see quite a lot of both really, it might even be a tight race.

Fixed that for ya.

The R25 is a Yamaha. The Ninja never had a chance in this comparison.;)

I wouldn't be surprise if they created a 300R to compete with yamaha R3 once it comes out.

So you have the Ninja 300 and new R3 both inline twins with higher reving engines...Ninja 300 at 12,500 red line and the R3 will be probably the same, perhaps 13,000. We know it produces 42 hp at 10,750 rpm, so it will have a red line above 10,500. Looks to me like the R3 being lighter and with more displacement, torque, and hp will be slightly faster and have a higher top speed than Ninja 300.


Then you have the thumpers. Torque is a good thing, but in a thumper it comes at the trade-off of a lower-reving engine. The RC390 red lines at 10,000. The Honda CBR300R redlines at 10,500.


If you are looking for acceleration to 60 mph, the RC390 is probably the faster bike, but top speed it will be 3rd, behind the R3 and Ninja 300, and ahead of the Honda. The thumper is fine for a naked street bike like the CB300F, but I prefer the in-line twins for this class of race bike. I think the R3 will eat the other bikes alive on the track.

It will be similar to GP, M1 vs the RCV's. Hondas are great in slow speed corners because of the low end tug, while the Yamaha's excel at carrying corner speed and higher revs.... 0:)

One has to admit - the Ninja 300 does look the mutts nuts.
The RC looks really hardcore.

Dam, they all look good. I do actuasly prefer the old total blue loo of the R6s several years back than the current R3 paint job (albeit up to date). The green on the Ninja is superb.

Anyway, the R3 looks too good to miss up but I will have to at least have a good look at the competition when i come to purchase time.
