I was thinking of buying a kfx450r but some people I have talked to have said stay away from the 450s. I do mostly trail riding and the guy at a dealership said a 400 would be better because "the 450s in general are a maintenance nightmare" this has kind of got me second guessing this quad so I wanted to know does the kfx450r need alot of maitenance and what is involved. I can handle changing the oil, lubing the chain, cleaning airfilters, general maintenance but I dont want to be sinking money into having a dealer maintain this quad.
