Just got back from Knolls OHV area in Utah where I put miles 170-200 on the beast in the company of three KTMs, a DR 400 and a CRF 250. I had by far the least experience offroad, but the little guy did great. Also excited that I apparently didn't blow anything up by dropping in a 12T countersprocket the night before. Hard to say, but I appreciated every little extra oomph for those sand hills.
Ran into a lot of deep sand (a first for me) - not sure the stock trailwings were the best choice there, but nobody was having fun for that section (soft sandy whoops)
Made some suspension tweaks before I went out (the old HF settings) - thought everything was great except a tendency to build up vertical momentum and buck me off during long series of whoops bits. Handled rocks, gravel, hard pack sand great. Swapped with one of the KTM riders for a bit (A 620 something, others were 525 EXC's)- wow what a motor! Still, pretty happy with the Yamaha and glad to swap back. Didn't have the torque to cover up my mistakes in the same way, but easier to muscle along in the fiddly bits.
Anyway - very happy to have been out. Would *not* have enjoyed this nearly as much on my other dual sport (F650GS)
