My 2006 level 4 must be a lemon. I get42 mpg. The stock tire,s do a great job. No wooble. Radio sound,s great. Is the most comfortable bike i ever sat on. Nav.does a great job. Best bike i ever owned.But then again im not a peg scraper.Iride with both handes on bars.(most of the time). All i seem to have to do is put gas in her and ride.Guess i wil have to trade to a 2007 see if i can have some problem,s.I feel left out.(oh i do have a left trunk problem).Guess even a lemon has it,s falts.
