No,Indian is not just another V-Twin and the Goldwing isn't just a Subaru.
Since we are off topic anyway,here is some expierence for me to share.
The R1800 is more like the Indian Thunderstroke than it is like the Honda.TQ not HP with low end grunt and pretty much done at 5500 rpms.
Both the 111(116) and R18 are air/oil cooled engines.That which means the heads actually carry oil pressure from a pump to the heads.The Indian carries 50/60 pounds at idle.Not sure what the R18 carries but probably around 50.
The Harley Davidson Vtwin is a splash system.Not bad but just what it is and been that way for manny moons.Btw,a oil cooler on a HD does not make the HD a oil cooled engine.A oil cooler cools the oil not the engine.Having a oil cooled engine is just that.The oil is pressurized to advance cooling kinda.
Here is a little history on the S&S designed Wedge and the Thunderstroke.Where it is believed the Thunderstroke grew from.
History:
I remember seeing the Wedge engine at the Laughlin River Run.If my mind serves me correctly it was 2002 or 03.The engine was a 56 degree Vtwin with 3 belt driven cams.The Thunderstroke uses oiled chains instead.The 3 cam design used the center cam for intake and the 2 end cams for exhaust.This allows the engine to keep a long stroke but keep engine height down.Back at the time I was interested in buying a X Wedge engine.Sadly,the folks at S&S said "The X Wedge won't fit in your Roadking Frame."WTF?
Crazy huh?Why would S&S build a engine that would not fit in a HD frame???Anyway,as the story goes, the idea was to build the engine 1st.Then build frame around the engine which came later.Funny,the engine was kept a secret under the code name "FRED"and of course the frame was to be called "WILMA".LOL,which S&S did build a couple frames, but did not to sell them.
I won't bore you with how BIG DOG ended up building a frame around this beautiful engine as you can do all the research you care to.Just thought I would share my personal expierence with any Bro that might be interested or that may have heard some rumors about how the 111

came to fruition.

My 116 only makes about 98hp at the rear wheel because of the the heads are designed to make TQ(125 tq @3000 and over 70hp at the rear wheel)
The engine is designed to have tq where a person rides yes, where it is ridden.
For comparison a good running twin cam makes around 50-60 hp @3000rpms.Funny folks get caught up around numbers,peak numbers.The real question is:How much throttle is needed to get the bike to excellerate or how many gears are needed to down shift to pass.The R18 was not made for Hp but for Tq.Hence a smaller boxer that makes more hp and less tq.
