the 2014 zx14r i got this spring is in a different league. i tell everyone i feel like the coyote sitting on a acme rocket.

if you are riding the bike a lot get the big ninja. if you are going to track days all the time and not riding it alot get the 10r.

when you open up the 14r you will be shocked.

i just sent my ecu out so i am hoping to get to cecil md one more time
Ring the 14s neck for 10 years. If it's still twice the bike I may look into either a low mileage, upper mileage well maintained bike that is stock unmodified for 1/3 list price.

808 i'm a strait up fan of our zx12s. but this 14r with the brocks meg pipe hauls more ass than the 12 does. when i get my ecu back i am thinking it will be even better. its got 30 hp on my zx12 and my 12 won many a shootout over a 14 and a gen2 busa with slipons giving them both over 100cc lol

see if you can ride one. just take it out in 6th gear around 3500 rpms and drop your wrist about a inch or more and feel how hard it pulls immediately and then stay in it and feel how it builds like it is building boost with a turbo. my 12 rips with the 17/52 gearing for the track but it would not be anywhere near it with the taller gearing the 14r has. i am down 2 in the back for wheelbase and it don't care.

I was on one before I got my 12. Around here, sellers want to drive a hard bargain for the 14. With the 12, not so much. I watched my 12 for two months. Met with the seller several times during that period and sort of became friends. I think he was just glad to see the bike going to someone that wanted it. There's another 12 here locally, nice bike, barely ridden and the seller not asking much for it and still much less than a gen 1 14.

You surprised me with your post. If I showed what came in the mail, you might just LOL at me.

Stock vs stock 12 vs 14 up here at mile high, trap speeds close. Not sure what gen 14 probably first. I think hibs has video of himself going at it with some 14s.

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 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.
