DIY Heat Shield on the BMW G650GS Sertao

I love my G650GS Sertao. It’s frugal on fuel, lightweight and just about powerful enough for most needs. I take it on short tours and love hitting the off-road trails with this bike.

But… I hate the heat this bike throws out!

Automotive heat shields!

Don’t get me wrong. This bike has never overheated. But I think it’s just poor design that the position of the fan is in such a manner that it blows the hot expelled air from the radiator straight into – my legs! Arrrgh! And in the mean time, much of these hot air also gets trapped underneath the plastic fairing panels. So much so that it can sometimes get unbearably hot around plastics where the thighs grip the faux tank.

So I purchased some automotive insulating heat shields and see if it helps.

Fairings removed. Heat shields cut to shape.
This bit of plastic fairing goes over the catalytic converter – and gets REALLY hot!
Some self-adhesive heat insulation applied!
Pretty pleased with how easy it was to work the heat insulation sheets.

And the verdict?

It definitely helped reduced the heat levels. The plastic panels no longer feel burning hot now. But for (heat) comfort, I still prefer my R1200GS LC over the Sertao. So I’d still choose to use my R1200GS for my day-to-day duties here in all-year summer Singapore – coz it’s not only cooler (temperature wise), but it’s also cooler (looks wise)! =P

  1. Hi. I have been riding my 1200GS for 5 years. Only within the last year, I started to notice the bike get really hot below the engine. Then within a few weeks, both my legs started getting tanned from the ankle up to a feet. Then it my legs gradually became more dark brown and spots appeared. I brought thr bike back to PML for inspection and all I got was a cold ‘nothing wrong’. Any suggestion?

  2. Yes. But i usually ride in shorts and sandals 🙂 . Now with the ambient temperature at 35C in the afternoon, gets really hot at the lower part of my legs. Wearing a thick pair of socks helps to shield them, but doesnt solve the problem. Should i change the coolant or install the heat insulators as well?
