Spal30103011 5.2in Puller Fan Paddle Blade 313 CFM

Installed quickly on KTM 390 Duke. Just had to swap the wiring harness and shave off one bolt hole. Quieter and moves more air. Fan blades seem more robust than original.

I purchased this to upgrade my bike's radiator.This thing can move 10x the air, respectfully.My temp never goes over to the three bar tier like it used to while at stoplights or in traffic.I recommend upgrading the coolant to engine ice & a 1.6 bar radiator cap for maximum efficiency.You do need to swap the wiring loom from the old fan and remove a bit of plastic for proper fitment.

This SPAL "low profile" fan competes with few others in this particular 5.2" (blade) diameter and price group, however compared to those, I think THIS fan is far superior. First of all, it is probably the absolutely thinnest and higher performing fan available for its compact size. It seems well designed and there is evidence of high degree of quality control in this Italian company's manufacturing process. I double checked the specs and found them quite accurate in terms of mechanical dimensions and the current rating of the electric motor of this fan. My application is a motorcycle oil cooler with very little clearance - barely enough for any fan - behind the cooler. There are obstructions on both sides - hot exhaust pipes - and directly behind the cooler, so the physical dimensions of the fan had to be no more than actually specified by SPAL. I do not have the means to measure the air flow rate, but this fan is spec'd at 342 CFM (at zero static pressure), which seems accurate based on my empirical testing. The OEM does not specify the rotational speed of their fans, but I measured ~5840 RPM.The minimum current spec is 4.8A at 13.0Vdc, at zero static pressure, so that makes it about a 62W fan. I measured 4.35A drawn from my 12V motorcycle battery at nominal voltage (not under charge).The only possible negative I can think of is that it does not come with a finger guard. It is certainly powerful enough to hack off a finger, but the trade off is that a guard would lower the effective flow rate at the expensive of a safer operational fan. Note, there is an identical version with a guard, but apparently not sold by Amazon. The only other potential negative is that this fan is plastic as opposed to metal, but still specified as waterproof to make up for any compromise in overall rigidity and durability.Overall, this fan will work well in my application with no fitment modifications required, so I am a satisfied customer.

Fan works great, as mentioned in many other reviews. For reference, I used this to replace my factory fan on a 2015 Duke 390. Install is fairly easy, only requiring one portion of the shroud to be trimmed down to fit factory mounting hardware. As an additional perk, the factory wiring plug can be easily swapped with the wiring plug that is included from Spal. This makes for a nice clean looking install when done. Would definitely recommend if you are looking for a more reliable/better performing fan for your 2015 Duke 390.

Bought this instead of the Aprilia OEM rad fan for my bike. This is the exact same unit that came off the bike, only at a third of the price as the oem. But it. Works great, fits perfect.
