For me the XT660R 2009 is a great combo with a good mix of everything, and is not best of anything...or perhaps the joy when all your buddies with BMW, KTM�s and AT�s getting stuck or crashing everywhere
There is no limit with this bike, unless you are going to race in real enduro/mx tracks with the horns growing from your head
Weakness:
Suspension (new fork springs is a must for true off-road, rear spring is to weak for me (105KG)
Engine protection is a big MUST, as you are bouncing around in the woods.
Open up air flow is a big gain of power and happiness, i recently did: DNA stage 1 filter (Replaced original filter) DNA stage 2 filter ( Replaced air box cover with filter ) and Kev�s O2 Controller + Fuel Mod 4= Much more bike that�s trying to get away from me
Have a blast...
