Keep in mind that the fastest, official record holding, & highly modified Ninja running regular gas still only goes 114+ mph in the States.

Because the Ninja is a little shy on the HP side, there's not a lot of power on tap to be had. The Ninja 250 is never going to be a powerful bike. The cost for the extra HP on the Ninja is pretty high for what you get.

Getting more HP, low end power or more top end, is going to be a trade off, meaning that if you want more HP, you lose low-end torque and HP to get there. If you want more low-end umph, you're going to lose top-end speed/HP. Also that great gas mileage you get goes out the window, when you start adding full exhaust, re-jetting and removing the airbox.

Some suggestions on mods for performance gains.

1-5bhp : Exhaust pipe, intake and jet kit.
3-8bhp : Porting, compression increase, cams, performance carbs.
20+bhp : Trade the Ninja 250 for a bigger bike.

Well Said

Do the Jet Kit get the exhaust then learn to ride your Ninja like no other.

I weigh 250# way too heavy to be competitive on a 250 in the straights...yet i have no problems keeping up in the corners .

the Jet kit will make the bike more responsive

with gearing, more bottom end torque will reduce your top speed....

If all you care about is top speed, get a liter bike, if you care about riding and twisties, master the 250.
