Radiator Fan Install

I was reading some threads on ADVrider the other day and came across another radiator fan discussion. "4play" had found a fan on ebay shipped to the door for under $30 bucks. After checking it out I pulled the trigger while it was still on sale. Here's a link to the seller on ebay - Click Here. Unfortunately the sale is over...But still a good buy!

Turns out it's the same fan (Spal 4" Pull) used in the KTM's but without the rectangle shroud . Oh well...I decided that some air was better than no air. After checking out the mounting possibilities and what it would take to fab a custom shroud I decided to mount the fan in KLR fashion.

K⋅L⋅R Fashion
–adjective.
1. unattractive or unpleasant to look at; offensive to the sense of beauty; displeasing in appearance.
2. disagreeable; unpleasant; objectionable.
3. morally revolting.

The holes on the fan line up almost perfectly with the XR's emissions tabs. I had to cut a little bit of plastic near the fans mounting holes so the XR tabs would line up right over the fan holes. I cut the bottom ears off the rad tabs and bent them away from the radiator slightly. This gave just enough room to squeeze the fan into position. I used some self tapping screws to cut threads into fans plastic.


I fashioned a mounting bracket from some aluminum and used a sealed pre-wired toggle switch with a rubber boot. The power is straight off the itty bitty battery. This will allow me to shut the bike down but still be able to run the fan if necessary.


My intentions aren't to run the fan unless I deem it necessary...ie - sitting at stop lights this summer when the temp off the asphalt is registering over 100F <-- Sunburn.

Not a bad price on the fan. Install looks great

Me likes....but how much is a radiator fan needed? Does the BRP really overheat that much? Is it stop-and-go traffic or general use?

Since the XRR wasn't designed to be a dual sport trail bike but rather for 90 MPH through the desert it makes sense that it wouldn't come with a fan. But as Hodakaguy once said all other DS bikes seem to have them...Why not!

How about running Evans NPG+ or NPG-R Coolant?

That's a "Push"...I think you want the "Pull".

Correction ...I use Engine Ice.
I've never had overheating issues but haven't had the bike out in 100F weather yet.

I know some guys who ride their BRPs in Summer here and the temps are regularly around 120. No problems if they have Evans.
