For starts the 690 is not a thumper. It's a short stroke high revving performance type motor , v a long lazy stroke of a thumper.
my understanding is that a thumper is a large bore, single cylinder, 4 stroke.
the 690 is the very best bike ever made in the big thumper class.
That's quite a bold statement, especially coming from an XRR owner. I don't want to stir a big debate (or maybe I do) but do you think the 690 is the "pinnacle" of the big thumper class of bikes? I know you rode a DR for a long time; do you think the 690 is the same type of bike but better, or has it become a different type of bike completely?
i do think the 690 is the pinnacle.
imo the KLR, DR, XT, XR & 690are all essentially the same type of bike: big bore, single cylinder, DS bike.
until the 690, the XRR was the boss.
as much as i like my XRR, i think the 690 is a superior bike: better suspension, better performance, better fuel economy, bigger service intervals.
