Well, i do SOME off-road riding..
I always take my summer vacations with camping equipment with my wife.
2-up or she rides her own bike.
Mostly fire-roads and some light trail.
No jumps, no rock-climbing, no tree-logs jumping...

The most use the XT660ZA gets, is daily commuting and 2-ups, on tarmac.
That's all, but I find it very disappointingly set up for every day use.
The front tyre jumps a lot on tarmac bumps and I feel like I cannot trust it on most situations.
