Member Contributer Ughandi Posted February 9 Member Contributer Posted February 9 I did ye olde uno reverse card on the 5th gen fan, as many others have... and boyo boy does she pump that stuff out! Took an easy afternoon. One beard out of three difficulty. Just needed a quick drain of the coolant & we were good to go! PN: 19020-MBB-003 - side plastics removed & coolant drained. - Popped off the rad. Only one wire running to it. - side to side comparison - installed - and just like humpty-dumpty, it's back together again --- Video after the fan kicked on: PXL_20250208_204004430.mp4 5 Quote
Member Contributer mello dude Posted February 9 Member Contributer Posted February 9 Add the trivia from a long time VFRDer.... If you ride in stop and go traffic... .ie.... very frequent where you are dead stopped in traffic less than ~10ish mph for longer bout... the stock fan is better. Sans that, if most of the time, maybe some infrequent SnG and moving 15 + mph, the VTR fan is the better... ---I'm running the VTR fan... YRMV Cheerz 2 Quote

The VFR has become my princess bike, and my transalp is my dirty daily, so long trips where traffic is an issue are not a concern for me anymore. ---- I do like the philosophy that ducatis go by when it comes to heat (perhaps it's 'copium', perhaps it's Stockholm Syndrome), and this mod supports it: "If you're hot, the bike's cool." 1 1 Quote
Member Contributer Mohawk Posted February 10 Member Contributer Posted February 10 Best add a stone guard grill to the air in area in the front slot that allows air in between the engine & back of the fan. The VTR fan will destroy the rad if a small stone gets spat in there that is larger than the slot between the round blade guard & the rad surface. Approx 6mm will fall out, anything larger will get moved by the fan blade folding over the rad fins. You have been warned. Quote

A fully enclosed fan shroud except for the front edge and some perforations for airflow. 3d printed. You could have a market if it performs Quote
