I’m just started looking at bikes im going to get one next summer when I pay my truck off. I’m planning on getting the 650r. I’m just trying to suck up as much info as possible now on all bikes. But heres my question? When looking at top speed, quarter miles, and 0-60. These bike look almost identical. So why is the Zx-6 such a more aggressive bike besides sitting position.
I know that one has a inline4 engine and the other has a parallel twin just wondering what makes one so much stronger then the other

The ZX-6R is a surgeon’s scalpel. It is extremely sharp, does exactly what you tell it to, even if that is just an unintended movement, and will do very serious harm if you don’t know how to handle it right.
By comparison I’d call a 250R a nice camping sheath knife. It’ll do anything you ask of it, it still takes some respect and control, but it is weighted well enough to comfortably handle most anything with it without cutting you.
If you don’t work with knives on a regular basis, this comparison might be useless to you

http://www.twobros.com/Cust_Service/Dyno_Charts/index.htmfirst lets look at the Ninja 650R
http://www.twobros.com/Cust_Service/Dyno_Charts/Ninja650R_2006_hp&torq.pdfHere we see two things, a fairly steady climb on the hp, with only really a 10 foot pound torque gain through the entire powerband. So she’ll tug harder up to about 7k, then the torque drops off (notice the hp doesn’t, that is because hp is a factor of torque AND rpm). This means it will accelerate slower above 7k than it did below, but it will still have plenty of power to keep you moving. Also notice the scale, We are now talking about torque in excess of 35 pounds throughout the entire usable range. More than double that of the ninja 250.
Lastly, lets look that the ZX-636R
http://www.twobros.com/Cust_Service/Dyno_Charts/KAW_05_dualvale_zx636r_torq&hp.pdfOn the torque side of things, it climbs to a similar peak, from a similar low, but it is almost always above 40 pounds. The 650R only makes 40+ pounds for 3000 rpm, the 636 holds it for 7000.
Move over to the hp chart, and we see it is already making the 650R’s peak hp at just past half way through the rpm range. It climbs a similar slope, but keeps going to almost twice the power of the 650R.But it isn’t just about power. Honestly, power is only a small part of what makes the bike hard to handle. “Handling” is a bigger issue. The ZX-6R turns in much sharper and faster than the 650R. Most cars take 2.5 turns of the steering wheel to reach full lock. So you have two and a half turns to accurately get the wheel where you want it. Supersports are like taking that making it only 1.5 turns, Suddenly every movement on the wheel has that much more of a magnified effect. You have to be smooth and subtle in your controls, over corrections are dangerous.
Then you add in the brakes. Just like the quick throttle can land you in trouble, so can powerful brakes. Go into a corner too fast, panic and grab your brakes to slow down, the bike will “high side”, that is, stand up and throw you off it.
