Thanks a bunch gooter! I would be interested to know if your Duke heats up after more than 10 min. of wide open throttle. If it doesn't, and your replacement radiator is the same size as the original, it appears the original fan is inadequate and the rest of the system is OK. I sure would like some pictures of your setup. My Duke will heat up within a few minutes of riding with the fan off and creep up past the halfway if I don't turn the fan on. Doesn't matter the speed it will overheat within minutes if the fan is not turned on. A good fan sucking the heat out of the radiator is the way to cooling these scoots.. Ur radiator is sufficient enough as long as it's not leaking like mine was. A fan...dedicated battery and Google a simple DC circuit to hook it all together....ur golden! |

I just installed a new radiator on my Duke.....got it off amazon for $34....strapped it up with some pipe strapping mounted in front of the engine but still behind the gas tank.....bought that siliconintake 7" fan $24 and a $25 12v 12ah battery off amazon also.
The battery is dedicated to the fan....put it in the trunk on a fuse with a switch located on the access panel for the spark plug coil.
The main thing I have found with my Duke is to keep it cool with airflow....gotta let that siliconintake fan suck the heat out of the radiator.
I have the oem fan mounted to the front of the radiator on a the unused light switch on the right side of the handle bar....this fan is only a back up....the radiator temp sensor is disconnected.
The scooter stays very cool now...I just leave that siliconintake fan running most of the time but cycle it off to let the thermostat open every so often....the fan is a low amp draw....super powerful....temp gauge struggles to reach to the half way mark.
