Welcome from one newbie to another

I've just got an XT660X and I test rode the Ten when I tried to decide. Some of the lack of power, comming from a road bike, may be the change in tyres, there is more rolling resistance on off-road tyres.

I found the Ten is deceptive with it's power, as are the XTX, your doing higher speeds than it feels as there is little urgency.

From reading the mods, exhaust,fueling and air filters seem to give the biggest gains and transform the bikes. I'm going to be getting my exhaust in a week, then filters after!

Enjoy the bike!
