Radiators are getting scarce, Anyone tried these two models on their 636 yet?

[oemsrt4]

I just put a fresh engine in my 03-04 636 and want to preserve it for as long as I can, My last bike ran/runs awesome, and the cooling setup never let it break 200 degrees. That is my goal with this new engine.

My first choice was an 05-06 636 radiator but didn't find any on ebay in minty condition and reasonable price. I was looking at maybe trying an 09+ R1 radiator since they have two nice Panasonic fans already built in, or a zx10 radiator and making my own R1/R6 dual fan brackets for it.

Here are some pictures for comparison:

zx10


I am leaning towards trying the R1 radiator with dual fans already built in out, wondering if anyone has tried it yet? I will have to make my cage and mounts for sure but its going on a steel frame so a off the shelf radiator cage most likely work anyways.

Let me know what you think!
