Had a zx12-PCIII,stock except for muzzy trigger advance(4 degree).Quick,fast.Excellent bike-tad buzzy. ZX14-Master,smoother,as quick(handling,acceleration).Better brakes-better bike. More options.More power.:mfclap
aaaaa this topic always comes up.... to each their own, zx-12 owners are willing to chop off one nut defending their bike's supremacy, while us zx-14 owners grin... who knows? A friend of mine has a 12 and was dying to drag me a quarter almost stock, his only mod being a sawn-off pipe and a slam/stretch. So far it hasn't happenned and my baby got yoshi slip-ons now, but is something I am eager to find out.
I would only add that my regular riding partner has a 12r with a head kit on it, PC, slammed and stretched 6" and I got him in every respect! Granted I'm slammed and running a PCIII with filter and flies out but even when it was stock I was still taking him everywhere. No dis to the 12 owners I really do like the 12 I think it is one of the best bikes ever made but it is not a match for the 14, Performance wise that is, looks wise I feel like many do that is truely a matter of taste.
HJey guys: Old thread but very relevant. The 14 wins on displacement yes, perhaps refinement among other things, etc. but shave off some of those cubes and what's really underneath.
Wet weight: 545 lbs. 91.2 lb-ft at the wheel. 1.24 lb-ft per in3 (73.2in3)
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
