All Good
I just bought a 2006 1200C last Fall. Recently, a friend of mine traded his '04 1200C for a SuperGlide. I rode the Superglide and liked it alot.
The FXDI's (his is a custom) aren't much more than a Sportster.
However, my Sportster is definitely quicker, and in short distance seems to easily outrun the TC88 - both bikes are essentially stock. With that being said, the SuperGlide (the new ones) handle great, and may be better for 2 up riding, which I do a fair amount of.
So yes, a Superglide may be a "trade up", but everytime I ride the 1200 it's a blast....and call me old fashioned, but I also like the carburetor.
I think one has to be careful here. This is my first HD, and it seems likely that yes, I'll trade up. I've already looked and run numbers, etc. But, I also know people who get the bigger bikes and find them less "fun" to ride.
I'd love to have 2 of the damn things really. Just don't give up your SPortster though if you like it, and cave into the HD peer pressure thing. Just ride and have fun.
Oil: started using Amsoil MCV 20 - 50 engine and primary, at 500 miles Bike seems to love it. Shifting smoothed out, and bike revs very nicely.
