I owned a DRZ400SM, and borrowed a buddy's LC4 a few times........both bikes left me wanting. Both needed another gear (as you pointed out) for the open road. The DRZ just didn't have enough motor, and the KTM vibrated my hands & feet to numbness at speed.
While I'm not as tall as you, I'm a big guy at 6'/240 lbs.......the DRZ's ergos were cramped for me - the KTM fit much better.
I picked up a 2008 "Hero Deal" 610SM when my SuMo itch needed scratching - and it's been a gas so far. Ergos-wise, it's MUCH more suited to me than the DRZ - and feels better than my bud's Duke, mainly because of the relative lack of vibration - it's surprisingly smooth for a big single.
I'm finding 75 to be max comfortable highway speed for me - seems like it's in a groove right about there. Much more velocity, and you can really feel the buffeting. Okay for short bursts (passing), but not what you'd call ideal for sustained travel.
What I'm enjoying about the 610SM is it's ability to accept steering inputs well - you can put it where you want it with no drama at all. This bike excels in the twisty bits - an absolute joy to ride at pace on your favorite roads.
The 610SM is a capable and substantial machine, useful beyond the usual SuMo niche. The motor is strong, the sixth gear makes a big difference on the highway, the brakes are stellar, the chassis is imperturbable, ergos/suspension are suitable for a bigger person, and it's good looking too. What it does need is a better seat - I've got one on order from Renazco Racing.
Guess you can tell I really like my Husqy 610SM, eh?
FredE pretty much hits the nail on the head. I've got an SM610 and my guy is on his 2nd LC4 640e. He has the full SM set up, including a MotoMaster caliper and Magura mastercylinder. He's got a full titanium Akrapovic exhaust and a Keihin carb. It's a whole different bike with just the addition of the carb, but the thing is a paintshaker, for sure. My eyeballs rattle in my head when I'm on it...seriously, it's hard to focus my eyeballs...it's the weirdest thing! My 610 is butter-smooth by comparison.
I'm a big believer in the 6-speed gearbox. I think every bike should have one and that was one of the factors in my decision to go with the Husky. I have cruised many miles at 70-80mph and it didn't feel like I was stressing my motor at all. The wind at those speeds is not the friendliest thing in the world, but I'm sorta used to it as my regular streetbike is naked.
The longest day I've done on the SM610 was 250 miles, mostly pavement with some 4x4 roads thrown in, and I was able to walk normally the next day

The seat isn't as rough as my stock KTM 450 EXC seat was, but a Guts Comfort seat would be a nice addition. A Renazco seat would be great if you can come up with the money.
My guy is 6' tall and he feels a little cramped on the 610. He likes his
LC4 because he says it feels like a Cadillac - big, comfortable and heavy. It's nowhere near as nimble as the 610, as the weight of the LC4 is all up top. I have no idea where the weight of the 610 is because I don't notice it
at all on the street. It's a little heavy for me in the dirt as I'm only 5'1" and it's much heavier than my other dirtbikes, but it is the most fun bike I've ever owned by far, no matter where I'm riding it.
FredE is spot-on when he says the 610 is a substantial and capable machine that is far more versatile than your average run-of-the-mill supermoto machine. It really is the do-it-all machine I hoped it would be when I bought it.
