I Ride: 2013 White Strada
Lane splitting is only legal in California.
There's already 2 fans behind the stock radiator. Not sure where you would fit another.
Pretty sure my fan comes on around 210F. The highest temps I see on hot days is 212F and the fan is always running then.

I'm on the same boat as the TS. I live in the philippines, we only have dry and wet season, as well as monstrous traffic jams in manila. During dry season, ambient air temperatures of up to 40C is quite normal. Couple that with being stuck in traffic and the coolant temp shoots up to 110C. At that temp, the motor often stalls when rolling off the throttle in stop and go traffic. The subframe where my thighs rest heats up to a level unbearable to any normal human even with thick denim trousers. I sometimes stop at a gas station and wipe down the subframe with wet rag for it to cool down enough so i can ride it. The oil cooler mod makes perfect sense. I'm also interested in any mod that will keep temps lower

Just to conclude this thread: I bought a switch from aliexpress to manually control the radiator fan and it helps a lot. I turn on the fan manually when entering the city and leave it on until I'm home. Still hot, but more bearable. Doesn't draw too much additional power and bike starts as normal even after leaving the fan on full time.

Further update: Couple of months ago I neared home with the fan switch on. Suddenly the dashboard lit up like a Christmas tree. I made it home, but with the error messages I wasn't confident to ride it further so took it on a truck to the local unofficial Ducati guy. He said the fan was on, but temp still reached the point where the ECU tried to start the fan, realised it was already on, and got confused. So, he took my switch off and cleaned the radiator with brake cleaner until it looked like new. Since then the bike is still reaching 104C but not spewing hot air out of the sides to the same extent and I consider the problem permanently solved. Thanks to all for the input, I appreciate it. And the Hyper has actually become my city bike of choice :-)
