Hey. Can anyone help me, I am looking to put a zx12r motor in a zx9r frame and I am wondering whether it is possible. Any comments or website links would be appreciated. Thanks.

here ya go.........

I think it would be a hell of an expensive transplant..........they are *totally* different design frames.......

good luck

lil' secret courtesy of the 'silver' book
I remember reading that.....
the 12's original frame design was done using a 9r engine
and the 12R engine started out on the drawing board
....as a bored out 9R

so maybe not so hard

NFI, but do let me know what you''re doing with the 9r motor if it ends up hapenning mate

hmmm, maybe there *is* something in that.....see, thats what happens when you don't have the damn book !!!!

It would be a *hell* of a hybrid.......I don't think a stock 9R frame would cope with the HP of a 12, but of course you can always brace them.....

hmmmmmmm

as the book sez
soon as they stuck the proper 12r engine in the frame..blah
so
the 'trial' monocoque frame got re-done..to what we know today
is in the 12

Top idea but .... dont you have to remove the tacho n the rear brake caliper (and everything plastic,metal,rubber & liquid inbetween) to change the spark plugs in the 12r now ?.

yeah completely different frame design... 12R goes over the engine, 9R goes around the engine

but hey nothings 'impossible'

what about if you put the motor in a trailer and towed it behind the bike

The engines mount up the same way, though; top and bottom bolts across the back of the gearbox and a bolt on each side at the back of the head.

I sincerely doubt that a 12 head would fit between the 9 frame rails, though. The 12 is a significantly bigger engine.

yeah by that i meant "if the engine is too big to put a frame around, how will it shoehorn into a little tiny 9R frame"

It's not, though. The Busa and the ZZ-R11/1200 engines are both bigger than the ZX12 unit, yet they both run conventional dual-beam frames.

The ZX12 doesn't run that monocoque frame because the size of its engine made using a conventional wraparound dual-beam frame unfeasible.

And yourself I'd reckon!!!

Thanks for the feedback. Has given me something to think about when it comes to attempting to transfer the motor into my frame.
