I tired with a SM450 and a TE450 and it just isn't a "dual sport". Its a race bike. It's a race bike. It's a race bike.
Bigger tank, wider seat, taller overall gear: still a race bike. I took mine on a 5 day trip with a drz, xr, dr, and ttr and honestly wish I had there bikes 95% of the time
the TE just wants to GO. Not cruise.
AMAZING machines once your are in the nasty twisties or trails, but suck getting there unless Trailering
The 610s are a blast. Big compared to what you're talking about, but loads of power, 3 gallon tank, easy maintance, and will run down the highway easy if needed too. What any jap 650 wants to be.
