[GasGasDreamer]

congrats on your new gg !
you'll fall in more in love as time rolls on.
i too have a husaberg [02 fe650e] and a gasgas [06 ec 300]
they are very different and want to be ridden differently.
for me, any issues are rider related mostly and not the bikes.
i find that i can go places and thru stuff with the gg with ease
that the berg would be plowing thru.
the 550 is a nice motor but there is something about the two stroke
that allows it to glide over the terrain where as the 4 stroke digs into the terrain.
try a pirelli trials tire on the rear [its the cheapest, can be run flat, and has the thickest sidewall] and you will be able to tool up anything.
are you a memeber at the uhe [husaberg.org] site? great site for bergs.
best of luck
