1198 powered Streetfighter

Has anyone put a Superbike 1198 engine in a Streetfighter? If so, were there any surprises as far as fit?

I've got the itch for a winter project.

IMHO that engine in its current form would be a huge disappointment in the SF. On the road that bike has terrible reviews. It need to be on the track at near redline to perform. Kind of contrary to the role of the SF.

I'll stick with the superior 1098.:)

It has been done a couple of times. There's a thread on here somewhere with the swap.
Don't expect a huge change in performance unless you heat up the engine first.

The airbox on the SF is the HP limitation and the reason for the 5 HP difference from the SBK.
You will still have the same airbox and injector limitations but it should be a direct bolt-in with very little mods depending on what injectors you use.
A custom airbox could improve breathing.

You will have to use the 1198 head pipes and have them modded to fit the sf exhaust.
An 1198 exhaust requires a complete 1198 or 1098 rear subframe, bodywork, and seat and there will be some mods where the bodywork and seat fit the tank/frame.

You might consider what Guido did with his bike, and that's a performance build to the original engine.
I think he ended up with about 170hp to the rear wheel! There are pics and a discription of his build around here somewhere.
As far as I know his bike has the hottest engine on a SF to date besides the 230hp turbo bike built by drag racers down in oz.

Thanks for the great information on the 1198 fitment and performance in a Streetfighter chassis. I did not know that the airbox is the limiting factor so I guess I'll get into this a little deeper now.

I'm actually looking for 100 ft. lbs. of torque at the rear wheel so there may be a better and easier way to accomplish this. Does anybody have any ideas or a better direction?

Some nut had a 1262 motor in a Streetfighter a while back and I hear it was crazy fast:)

One tooth down in the front and one tooth up in the rear. Or more. Did this to my inline four and it was a big jump up in torque. If you already have done this then I guess you need the bigger engine. But have you ever seen the rear sprocket the stunters use? They're huge. Wheelies on command.
