Many people do fine with Hogs and lets be fair, what Peter and Kay did with theirs defies logic regardless of brand, luckiest couple alive IMO, but overall it is a poor design that should have been easily changed in several fashions without all the added on nonsense.
Lets face it, Harley sells bikes on nothing more than Image and brand, that is it, for what you pay you do not get much at all. When I tell people I have traction control and ABS who ride hogs they are like what? Kind of the same look when I tell them the HP many of us would like to see improved slightly. Lets not forget about the lack of ES.
I have a dear friend who went thru a few Japn bikes he never really rode, then bought a newer RK. I thought he was nuts, why shell out that kind of money if you are not going to ride?
Now he is always on the road, whatever it takes I guess.
H-D's does indeed have to deal with that issue. Their duty service bikes often come with a fan to blow across that rear cylinder.
BMW and Moto Guzzi don't have that problem, the cylinders sit outboard in the airstream.... but air/oil cooling has limits.
I agree, although I did ride my Virago for 13 years ::001:: The only thing that bike ever needed was fork seals, crazy.
