The 14 wins on displacement yes, perhaps refinement among other things, etc. but shave off some of those cubes and what's really underneath.

zx12r
Wet weight: 545 lbs. 91.2 lb-ft at the wheel. 1.24 lb-ft per in3 (73.2in3)

zx14r
Wet weight: 593lbs. 113.2 lb-ft at the wheel. 1.28 lb-ft per in3 (87.9in3)


Difference in torque per in3: .04 lb-ft to the zx14r. At the same displacement (73.2 cu in) of the zx12r this would amount to 93.69 lb-ft (1.28) * 73.2 for an increase over the zx12r by (93.69-91.2)= 2.496 lb-ft. or roughly 3% more

Difference in weight: 8% less goes to the zx12r
At the same weight and displacement of the zx12r the zx14R would have to make (1.08 * 91.2) = 98.496 lb-ft to match the zx12rs power to weight. Therefore at the same displacement as the zx12r, the zx14rs 93.69 lb-ft is (98.496-93.69) = 4.8lb-fts or roughly 5% less.


Although power to weight is usually between hp and weight, here let's use torque. The difference between the two, .03-.05 = -.02 = 2%. Older technology does not equate to less performance

All my #s for both bikes are from wiki.

One thing I don't think I have seen people talk about on the forums is the relation between gearing and suspension or at least in recent memory . When it's said that going down in the rear, or even going up in the front and the bike still feels strong, is not in itself just raw power. What I mean is that say you go down a tooth or two in the back but the bike still feels really strong. Say for example you're doing that on a 14. But now say
you do it on another bike for example a 12. But the feeling is not as powerful. Aside from displacement and differences in power the suspension between the two is going to be different so the feel shouldn't feel the same.

On your bike try this. Set your rear suspension full tight. Now blast off and see how it feels. Then on that same bike set the suspension full soft and blast off see the difference. This is a reason I believe when some guys say then went -1 +1 and it's not uncommon to hear the reaction of worn arms, torn arms, etc because you are feeling the full effect without making changes to the suspension. Conversely going taller with say 1-2 down in the back, but now make the suspension even more tighter see how that feels.

Basically what i'm saying is that carrying taller gearing without increasing hp and still feeling the rawness is probably because your suspension is probably tight to begin with.

Something else not talked about is how khi (perhaps it is at a different venue) is able to increase cc's while maintaining V.E. Or is that old news already? With their forumula, a na 1500-1600cc bike would give the term radical new meaning. Perhaps with the superchargers khi might be planning a future with the big cc bikes a thing of the past. Is that old news already too? There's a lot to like about khi's direction, but even more so when getting a sc bike at a great deal may only be 15 years away. Comparatively speaking while there are 12s around.

I have no distaste of the 14. Think it's a helluva machine. When you hear 14 owners describe how it's the easiest big hp bike to ride that reminds me of why I like the 12. It's not that easy to ride and my bike is actually setup just for that. It's turbo without the lag when it runs as it should (my perception) when ridden primarily in the city. Keep maintenance in the rear view mirror and always be ahead.
