I agree with Dave about the KLR's long travel suspension, but also have a slightly different opinion/ point of view about it. No doubt that soft, long travel suspension is gonna feel all mushy on a nice groomed road. Ever notice how loose the Motogp bikes get with the slightest contact of a curb?
I've had some good handling ( not overly great) bikes in the past and the stiff, short travel suspension that makes bikes bite in to the pavement so wellat high speed is only as good as the road itself IMO. In the rough, bumpy, cracked up backroads I live and ride on, the KLR's long travel, soft suspension actually helps it conform to the road surface and actually allow it to grip the road better. Notice the sumo craze? I think that's a large part of it IMO.
For example, I had an 1980 CB750F that had been updated with CBR forks( internals had been worked over), wheels, brakes, etc. It was still riding on older twin shocks out back, but the suspension was very nice and it was running very sticky 17" sport bike tires ( Pirelli Diablo Rosso 2's). There was one particular curve that I finally managed to get that bike through at 45mph. Pegs dragging, tires skidding and giving it my best. It was doable, but never comfortable. Always a rush. I took out a mailbox once with my helmet in that corner.
However, I now ride comfortably through that same corner with my practically stock KLR on Kenda Trakmaster knobbies at 45mph daily. How? The suspension soaks up the bumps and the tires stay planted. A riding buddy has a Ninja 1000 and he cant keep up with me in the mountains on my knobby wearing KLR.Eats me for lunch on the straights, ofc. His suspension is just too stiff to handle real life roads at speed. Like my old CB, the bike stays upset and can never settle in to the road.
Anyway, speaking of street tires, my KLR had Shinko 705's when I bought it. After getting used to the bike it would take the curve mentioned before at almost 55 mph with no hint of letting go. I was astounded.The bike was completely stock at that point. I think 705's are highly remarkable tires for what they are. They are abysmal offroad and on wet pavement, though. My need for the KLR has changed slightly so I will be going away from full knobs for a while.
The bike corners just fine on knobs, but I'm wasting my money chewing up knobs for street riding. I need to get more than 4-5 tanks of fuel out of a rear tire. lol. Gonna give Shinko's 244 rear and 700 front a go and see how it does.
