zx6rr motor or 636 motor install

[GIL with 1 L]

I know alot of people claim there is no difference, but I want to hear from people who prefer the zx6rr motor and why. Also is the zx6rr a destroked 636 or just smaller pistons or both

man that's a tuff one I thing the zx6rr has more torque for some reason??
might be in the transmission

Also are the gear ratios in the trans the same?

zx6rr is taller geared and shifts better,636 feels like it has a bit more idle pull,03-04 636/03 zx6rr share ECUs and harness,while the 04 zx6rr has dual stage injection and has a diff. ECU/harness....the 636 is way better IMO for stunting,not to say you cant stunt the zx6rr cuz i did...

I've had both and felt no difference at all

there def different. the zx6rr was built because the 636 couldnt not legaly be raced in the ama 600cc class... there is alot the same about the 2 but there are differences in the powertrain. they didnt want the bike to be faster than the 636 but they didnt want it to be slower either cause when it sold new it cost more money.. basically the zx6rr was a lil more track ready where as the 636 was more there street flagship 600cc model. im not sure all the differences in the 2 but i know there was alot. at least in the 05 06 models.
