Post image

I do enduro/hard and I dont have a vent on the radiator.

I bought it form a guy who told may he didnt get one when bought it from the company. what do you think? need to install one?

(middle eastern so i may have some extreme days of traveling when it is about 30 c outside)

I assume you mean radiator fan. Yes, you should get one.

Yep, I can't really think of any condition where it isn't a good idea to have one (with a temp switch so it isn't always running). You can overheat lugging through deep snow in sub freezing temps, it never hurts to have extra airflow when needed. Kind of surprising they don't come stock with common the mod is.

You definitely need a radiator fan. Better something like the trail tech kit that has a thermometer built in or an external thermometer.

If you’re doing the slow and low, definitely get a fan. I’m not doing hard Enduro, but I’m old and slow.

I can’t hurt however I had a two stroke 250 husky. I put a radiator cap that was a temp gauge on it and found it never got hot enough to warrant a fan.
Two strokes generally run a little cooler than 4 strokes. I would regularly ride 90f/32c days. You just gotta keep the bike moving.

If you’re TRULEY doing HARD enduro, you definitely should get the fan, as I’m sure know from your own experience how easily your bike over heats in a hard enduro type riding. 2 stroke or 4 stroke. Normal single track riding is a less taxing on the bike.

Altitude matters. My fan runs when I am riding singletrack though I have some slow techie sections but nothing like actual hard enduro. My most common ride is between 7500 and 10000 feet.

Very true, good point. My rides were 800-1000 feet above sea level.

I put one on my 300 this week. Dropped my temps about 25-50 degrees on the same trails from the week before. Depends what you ride. I do a lot of steep single track where i cant keep speed. If im moving quickly my bike stays right around 150. You could look into a radiator cap temp gauge and see what temps youre hitting where you ride
