Kawasaki Ninja 250 FI VS New Yamaha YZF-R25


 
Everybody knows the Yamaha already launch the Sport Bike in 250cc class. But is everybody know how well this bike on the track? Is it stiff ? How this bike accelerate ?
The only thing that we can do is battle it with the old player in 250cc class, "The Kawasaki Ninja 250FI".
With similar machine specification, 2-cylinder DOHC 8 valve. Let see the results!

Riding Position

Sitting in the seat are both fairly similar, although the use handlebar clamp but it still has a comfortable sitting position. Not too stiff for daily use.
The difference in R25 owned flatter handlebars, while Ninja slightly bend downward.
The R25 has narrow and high tank, different with Ninja with medium low and wide tank, but both of them are still equally comfortable. The next difference is R25 soft rear suspension. 

Handling and Performance

Let discuss about the handling. With a weight of only 166 kg and the average distribution of 50:50 front-rear, R25 lighter and more agile to maneuver, especially the angle turn the handlebars only 34 °. Ninja 250FI are a lot heavier, with a weight reach 172 kg with a slightly wider turning radius.
When throttled up, R25 still win for this, because the 25 ° rake angle and the 95 mm trail, makes it turning and maneuver so easily and accurate. Ninja who had 27 ° rake angle and 93 mm trail, it took extra effort to take this beast turn in the same speed, but you will get much and much comfortable when you meet straight path.
The Characteristic of the suspension also influence to handling, the rear suspension of R25 Mono cross are very soft, at high speed rear wheel of R25 can easily moved. Differences with Ninja, uni-track mono shock got slower compression but rebounded quickly, it makes you get a great stability but when you met a bumpy road you will get shocked when you riding Ninja.
About the performance, measured power on Dynojet 250i dynamometer owned by Sportisi Motorsport Indonesia. Power of R25 reach 29.43 hp / 12,100 rpm and a torque of 19.2 Nm / 10,200 rpm. Medium Ninja 250FI 26.21 hp / 10,800 rpm and 17.87 Nm / 10,000 rpm. You can see it in the graph of dyno results below.
 
As expected from the dyno test , we are trying to test it in real condition. Ninja can only offset in the initial attraction 0-60 km / h with a time of 3.1 seconds, after the R25 left with a gap between 0.2 to 0.5 seconds. You can see the details below. R25 Top speed was best to 170 km/h , the Ninja is only 161 km/h.

Gasoline consumption

Had the same engine configuration, the 250 cc 2-cylinder DOHC 8 valve petrol supply injection and liquid-cooled. Bore x stroke both overbore make better play at high rpm, then do not be surprised gasoline consumption is quite greedy.
Both bike used daily on the streets of Jakarta (writer from Indonesia), with varying road conditions produce gasoline consumption is not much different. R25 22.7 km / lt, while Ninja 250FI 21 km / lt.

Conclusion

If you are looking for comfort and stable riding for straight path area you can pick the Ninja 250 FI as a great Beast, but if you are looking for a bike for maneuvering racing Yamaha (Revs your Heart ) is the only candidate.
That's is our opinion. How about your opinion ?
