The new 2010 Husquvarna 510TE that we just picked up was ridden one day. The short comings in quality control and engineering are too numerous to list, but a routine post ride inspection has been a week of fixing.
Fuel pump wire pinched, gas tank held on with one bolt at the top, grossly overweight fuel pump, battery fell out of its holder when hit by rear tire that bottomed in it's suspension, wiring so poorly done that I finally just redid a lot of it, vibrates a lot, exhaust pipe that truly needs better shields, some head shake, some bolts so tight that the plastic under them was completely broken out, some so loose, they fell out after one day (only about 2 hours total).
I like the bike, but it ain't all that over the KTM.
