BB...no, actually the Yamaha Stratoliner is the bike I had in mind with my comment, and it is air/oil cooled. The 2012 Deluxe now has a fairing with Zumo 665, Ipod, etc. No lowers and no TP, but hard saddlebags. The engine is the same engine I had in the '06 Strat I had...1854CC (113") 48 degree VTwin, with 4 valves per cylinder (pushrod operated), two 43mm Throttlebodies (vertical downdraft), 2 spark plugs per cylinder, Ceramic coated cylinders for heat dispersion. Other stuff. It's one of the closest in looks (the engine) to a HD, other than there is no primary. Virtually the same RPM band, with maximum TQ at 2500 RPM. Runs on REGULAR gas. Better suspension front and rear. Great brakes. Hydraulic Clutch, blah, blah, blah. It even sounds a lot like a HD VTwin...not the same, but close. It's not perfect either. It's a very nice bike in present configuration (Deluxe). I had no issues with mine other than they only had one model (at the time), and it was very much like a Road King. I like a full fairing for a number of reasons. It's not a HD though.
The only point is that HD could do some things to make the engines run cooler, without necessarily going to water cooling, though that is inevitable in the long run. BMW boxer engines are still air/oil cooled. Not apples to apples, I know. But, things can be done with design of engine components to get them where they need to be and still maintain the whole "HD" thing. I wouldn't take anything for my SERGU...it's the perfect bike for me. But, I don't look forward to having to do some kind of engine work at 30K or sooner (50/50 chance, at best) due to chitty lifters, valve stem seals, crankshaft...whatever. The odds are pretty good something will need to be done well before it "should" need to be done.
But, getting back to the point...there is NO reason HD can't put better suspension on the bikes. They ALL need it, including the VRod. If they did it at the factory, it MIGHT cost them $500 per unit to put something really decent under the bike, and the typical HD customer would not think twice about a $500 increase in price, particularly if they are getting something real in the process. In cases like that, it's either HD just doesn't GAS, thinks people are happy with things the way they are (mistaken thinking), or is simply 5 years or more behind the curve. So, those of us who know change things like that out to aftermarket products of one kind or another. I'd rather just pay for it up front and be done.
2013? Paint and do dads...
