One of the things I might add, having been riding motorcycles for nearly 50 years, is the obvious. The bigger the engine, the more heat is generated. Honda dealt with this in 1975 by making the gold wing. 1000cc and a water cooled engine. This went to 1100cc's, then 1200, then 1500 and finally the 1800.

V-twins got larger and larger relying on air cooling. As Harley moved to the 107ci they added water cooling to the heads of the full touring models (concealed in the fairing "lowers") and oil cooling to the more stripped down touring models (e.g. road king) and the road king had an optional "fan kit" for the oil cooler.


Our M3W's have a 124c1 engine (as big as an 1800 Goldwing). While the transverse mount provides exceptional cooling going down the road, especially to the exhaust side, there is really nothing to dissipate the heat when not moving. Exactly why Morgan added the fan at low speeds.
