My wife and I just rented the KLR and did a 2-up ride out to south point and green sands beach. Fantastic ride! We had great weather there and back too.
South of Kona has some nice twisty sections of road and goes thru some nice old towns. After that, some long straight sections to get you to south point turnoff. Fun little single lane road down to the ocean and nice country scenery all the way. Then the fun begins - the lava rock and dirt road to green sands beach! This is a challenging road for two up riding in sections on the KLR, but we made it ok with a few bashes to the skid plate. The green sands beach was a sight to see. Very remote place that only trucks or dual sport can get to, or a really long hike. Well worth the ride. On the way back, my wife opted to get a ride in a truck from a local and I got to play on the KLR for a while!!! Theres lots of trails out there, and for a while, it felt Dakar like, with weaving in and out of the different trails crossing paths with the truck that my wife was in.
All in all, a great day of riding. I highly recommend taking a trip to the Big Island and hooking up with Jason for some dual sport riding.
