What size dual sport do you bigger guys ride ? I weigh about 245, feel like a 650 would be too underpowered
Most all of the single cylinder bikes make the same HP (save KTM), it’s just a difference in gearing. A KLR650 is a 80/20 street/dirt road bike. Honestly I’d almost say it is more of an Adventure bike than a dual sport. The KLR has been around the world more than any other bike. I like it for what it is, but know it’s limitations.
None of the Japanese offerings will make you happy if you’re looking for “power” out of a single cylinder motor and the suspension isn’t sufficient for most American sized individuals, If you think you need the power and suspension, get a KTM. They offer what you want at a price mind you, that is typically several thousands more than a Japanese dual sport.
Personally after having over 50 bikes, most of which have been dual sport and Adventure bikes, I’m leaning toward the Tenere 700. Not really any “bigger” than the current singles like a XR, DR, or KLR, but comes with a parallel twin motor and decent suspension.
