Congratulations, that bike looks like it will be a blast. I'll look forward to the RR. We were there a few years ago with a rental mini 4x4 and spent a few days climbing Cerro Chirripo and up in the mtns, then down south to San Vito and out to Puerto Jimenez to Carate and Corcovado, Then up the coast and over to Lake Arenal area. Made a couple of friends I'm still in touch with on Facebook, even though my Spanish is rudimentary at best. Be fun to go back for another visit so I think I will write to Wild Rider, especially now that I have an idea of what we'd need.
Enjoy your stay...I still remember San Isidro de General because I spent quite a bit of time shopping there for a propane canister that I never was able to find.
