Solid OEM replacement and upgrade RMZ250


Good looking radiators, they do fatten the bike (2012 RMZ 250) up a little and i had some issues fitting my radiator braces to them. But they do look sexy and have a lot more cooling surface area than the OEM radiators. The left side touches the frame on my bike so i had to fit some padding to stop them damaging each other.

Is there a number less than zero stars?


These are bar none the worst fitting aftermarket part I have ever used in 20+ years of riding. I ordered them for my 2011 KX450F after I caused a leak in my left radiator and couldn't find any oem model available in a timely manner.On the right side, they hit the cast portion of the "Y" above the cylinder, as well as several portions of the louvers, and the shrouds wouldn't have bolted up at the bottom without significant trimming of the reinforcing webbing on the shroud. On the left, the bolt holes were over 1/4" too far forward and the upper water neck was already hitting the tank, and the same area of the inside rear edge was hitting the aforementioned "Y" casting. The problem lies in the fact that these radiators measure approximately 5/16"-3/8" thicker between the center of the mounting hole (where the grommet goes) and the back of the radiator). Thicker radiators are a good thing, but not if you can't put them on your bike without major modification of the bike and/or radiator. If there is an upside, they do look nice and appear that they would work well if installed. I do not believe that they are the incorrect part because the fittings and general dimensions appear correct. It was odd that the box said they were for 10-12 model years as I was under the impression that 09-11 were the same and 12 was different. To BTO's credit they did not hesitate on the return approval and had told me in advance (when I asked before ordering) that these were fairly new and thus there was no feedback. It's too bad these were such a disappointment as they reflect (in my opinion) the appropriate pricing for such an item (Fluidyne is ridiculous in my opinion-I can buy a polished aluminum radiator for my classic car for less than a pair of those).
