#1 | S1000 XR radiator design datum

Thu May 21, 2020 7:53 am

About a month ago I purchased a radiator guard for my 2019 S1000 XR, I finally got around to installing it today. And I noticed that the oil cooler had a large ding in the bottom row so it looked like I just got lucky. The bike has 4,000 miles.

During the installation I got a real good look at the edge rib design of the radiator and noticed that BMW has built a guard into the design of the radiator! These guys are not crazy after all to put that huge coolant and oil radiator right behind the front tire. Look at the right edge of the radiator and you will see a layer of corrugated metal on the front of the radiator that is NOT a cooling fin.

Well done BMW! I installed the guard anyway, now I have belts and suspenders.

I suspect that is dual purpose; it's probably also cooling fins given the design (maximum surface area).

If it wasn't anything to do with cooling, then a fine metal mesh across the front of the radiator would have been cheaper and less weight

Looks like a cooling fin to me.

I had never seen a radiator design like the XR before, they all looked like the one below, where the coolant was inside the horizontal webs made of thin metal. This picture is of a Kawasaki ZX14, the shiny horizontal nick put a hole in that web and it leaked - and every radiator I have seen before was built like this.Radiator ZX.jpeg - Bild entfernt (keine Rechte)

I suspect there is coolant in the "horizontal bars" in your original photo (the XR radiator). I could well be mistaken, however. I often am.

I think so too. Except this is the lower one on the XR, it's the oil cooler, that's a very sturdy piece, ins't it. Upon closer inspection, the radiator for the coolant, the upper one on the XR, has the typical radiator construction and would benefit greatly from the GIVI guard.

Edit: replaced radiator with oil cooler as appropriate
