I will be very careful off road. No stupid stuff but just rather being able to keep riding "where the pavement ends". Damaging an artificial knee can be catastrophic. I've done quite a bit of off road riding, to include in the northern Yukon, so know my limits. I've also forded rivers but will watch the vids.
Lupe, I have a 31 inch inseam and can barely get on a stock KLR, and then standing on top toes. The low Sargent seat that came with the bike makes it pretty easy though for me and I can keep my feet flat on the ground.
