Ok, so some of you know that I totaled the 636 and bought an 07, the 636 was only cosmetically damaged so I kept it as my track bike. My kawasaki instructor absolutely raves about the the P model 6Rs (07-08) says they're lighter more powerful, turn quicker blah blah blah. Well I will say the the 07 is a nice ride and feels more rigid and solid than my 636, BUT I'm not convinced it's the better bike, so I decided to the compare numbers in the manuals and heres what I found.
07 does have more HP stock: 125 vs 118
Dry weight has the 636 lighter by 13lbs: 355 vs 368
But to be fair it takes .26 more gallons of gas and .2 more qts of oil, and who knows about the cooling system, so they may be pretty close there.
Now here's where it starts to get interesting:
Wheel Base - 1,400mm
Road Clearance - 130mm
Rake Angle - 24.5
Trail - 95mm
Wheel Base - 1,405mm
Road Clearance - 125mm
Rake Angle - 25
Trail - 110mm
This means that the 07 sits lower, has a longer wheel base, and has a rake and trail that will make it a little slower to turn in; by the numbers at least. Now I havent ridden the 636 since I got the new bike, so I can't give an completely accurate side by side comparison... but I can say that I miss riding the 636 b/c I remember it being easier to put into a corner and go through the really tight twisties that are my roads of choice. However if you were to decrease the trail on the 07 by 13mm and bring it to 97mm (wich is the ideal number according to my Suzuki instructor who used to be lead R&D at RaceTech) that would make the 07 lower, shorter
, and have a much better trail which could make it turn faster than the 636. I might have to play with this. Also I realize there are factors that I am not taking into account such as center of gravity, perhaps the 07's is lower, idk; I really just need to get back on the 636 and see if I still feel the same way.
Oh and one more thing, the 07 destroys the 636 in compression ratio with 13.3:1 vs 12.8:1
And lets face it, the B model 636's are just way prettier than the P model Zx-6Rs
