There is a wealth of knowledge on this forum. Please note a couple of things....The electrical issue with the EHC is blown way out of proportion. Someone did a poll on it a while back and the results speak volumes.
I have an 09 K9 and I love the bike to death. I bought it a year ago for 16,900 with around 4500 miles on it. I considered it a good deal, one to good to pass up. No real problems with it. Just changed all the fluids and now I ride it like I stole it.
My dad has a 06 Mastiff which is in the era of when the electrical issues were more prevalent, however he to has had 0 problems with his electrical system.
As for the low miles comment...it is not any one particular reason. These aren't Harleys, not alot of people can handle/want a bike that rides like these do. Alot of people want a soft, tame ride which is what Harley is good at.
You can ask my buddy (who rides a Harley) who gets more comments at the end of the day. You can also ask him what its like when I walk him like he's standing still.
So you have a question to ask yourself....Do you want to blend in and spend $$$ trying to make your Harley unique, or buy a bike that has the looks and American muscle to effectively put down any Harley threat?
