I probably at some point will look into more luggage capacity, but as you said, that's not what this bike is about. This is more of a dual sport hot rod, as I like to say. So for now, this is how it will be. For comparison, I currently have an 09 R12GSA, and have owned/ridden an 12GS, 1150GS, HP2, 950 AdvS, 950 SE, 990 Adv, 690ER, KLR, TE610, and XR650. Vibration: The SC3 is based on the hard mount 03 Sportster and yes, its vibey, but I have rubber dampers in the bar risers, so its not that bad. Compared to all the other bikes though, it still has the most vibration. Comfort: Based on short 100 miles rides - the SC3 is pretty similar to the big KTM's, and more comfortable than the smaller 690, 650, 610 bikes. The GS's are far more comfortable though, even with stock seats. Ergos are stretched out and has plenty of leg room with the new lower peg positions. Seat is a Corbin which initially feels hard, but after long miles, still feels pretty good. Off-Road: I think the SC3 fits somewhere between the 950's and the smaller 6XX's. Relatively nimble and agile for a big bike, but so far, I haven't pushed the limits like I used to on the 950/990's. Way more capable on techincal stuff than the GS's. The single pin crank on the Sportster has an interesting characteristic in that it feels much lighter when you ride it - not sure how to explain it, but I think it may have something to do with the flywheel mass, single pin, and firing order. Id like to hear others thoughts on this. At some point I'll get brave enough to let others ride the bike so to get un-biased opinions and input. To date, only two people have ridden it. My good friend Mark who I trust on it as hes a heck of rider, and David Edwards - who maybe will at some point write a blurb on what he thought.
