I am pretty keen on upgrading the mighty ATK 406 for the 400E Berg.
I havent been able to find out much bad stuff, mostly great raves and little info. Are there any current owners who can share some info with me?
I have a '96 501e. Originally I wanted a KTM 400exc or 520, but wasn't sure about all the maintanence stuff that goes with an RFS. So I got a deal on the 'berg and figured it would be good way to test the waters rather than plunk down the $7000 for the KTM.
The bike is pretty straight forward and easy to work on, get a manual though so you have some spec's & diagrams to work from. Adjust the valves and change the oil and ride the piss out of it! There do seem to be a few glitches with the different models, as with all bikes. The 2000 should be a safe bet. My only beef is with the Dellorto carb...sucks. And the lack of replacement plastic, graphics, footpegs & stuff like that. Yes the bikes are pretty trick from the factory but eventually you'll want to ad or replace some stuff.
