02 cbr f4i motor swap?
 

hey guys, i was wondering what engines bolt up to a 2002 cbr 600 f4i frame? im gonna be getting a different motor and its be cheaper to buy another one then rebuild the 600 f4i motor, what motors would work, also if i chose to rebuild whats a good place for parts???

lmk thanks

I don't know that I'd ever swap out an engine on a bike. Personal preference. I'd just go with another stock motor. That's all the input I have though. No idea on parts or anything. GL though.

As far as I know, only F4 and F4i motors will bolt up. Maybe previous generation F-series also, but that's just silly. Stick with an F4i motor.

Any year F4i, if you were thinking RR I don't think that would work, as the frames are different, but anything is possible with a little or alot of work.

+1 :icon_playing:

I was wondering the same thing but I would want a bigger engine like out of a 1000rr or something

Then I would suggest buying a 1000rr.

Yea but it would be a nice sleeper to pull up to someone on a f4i and then just spank them

You'd be hard pressed to use the power potential of a 1000RR motor in an F4i without flipping over.

it was just a thought I guess along the same lines as why we put a big block in my sisters 95 s-10 pickup

bikes aint cars lol, and a good rider could still spank it even with the 1k motor in it. :icon_wink:

The frame and the rest of the bike (BRAKES, suspension...) are not designed for that much of a power. Even if you could "attach" a 1000 ccm engine, it would be dangerous...

I run into this tread that may answer your question - looks like there is one more bike you could use an engine from - if it's engine can be put on a F4i, should work reversed as well...

if you have the money, i say hell go for it. but honestly, you should be able at least keep up with most anything out there, minus litter bikes in a straight.

the chances of being able to RACE the SAME bike and NOT hurt yourself with a different engine aren't worth the dollars and hours you'll need.

and more than likely it would be hard to get the bike balanced again due to different widths of motors and where the front sprocket is located. I think it'd be unsafe!!

I know that you can put a GXR-1000 motor on a GXR-600 frame. Havent heard of any more bikes that you can do this with, though.
