Water Cooled Rotax Swap?

[blacke30]

Has anyone done a motor swap from the 1125 to the lightning? I love the way the lightning looks but it would be bad ass to have a water cooled engine setup on there.

Seems even if you could do it and I'm sure it can be done if you want to bad enough. By the time you added the radiators it would look like a CR again. I might be easy and cheaper to get the CR and swap out the subframe and front plastic and be done with it.

I also was thinking of that as well. Swapping the plastics off of the lightning onto the CR.


Has anyone done that?

The frame won't accept the 1125 engine without a big hammer.

The frame IS different,
How do I know, I have both and have put insulation on the interior of both frames.

My vote is for making your cr look like a lightning, and seeing what you can do to replace those radiator cowls with something better looking. That would be much more valuable. The CR has grown on me, and the radiators don't bug me nearly as much, but I still think it'd look a lot better without.

SO MUCH WORK!!! Belts and swing arm swap. New motor and radiator mounts.... No thank you. But give it a try if you wanna tear up the Lightning. BTW it might cost you the same in parts as a CR alone.

I didn't believe a bike could handle better than the XB... at least not to the point that you could tell on the street. Boy was I wrong!!! I would say probaby a 400% improvement. I wouldn't try to shoehorn the 1125 into an XB, the new chassis is so much better you can tell even going in a straight line. Feel free to change plastics, move radiators, whatever you want but don't knock the R/CR until you have put some miles on it.
