I think I have it narrowed down to these two hardtail MB's. I really like the look of the Powerfly 4, especially in orange, but the reliability and 3 yr warranty on the Yamaha has its appeal. The Yamaha will also be about $400 less because the dealer is offering a discount and my local Trek store holds to full suggested retail ($3,699). Has anybody riden both and can provide some feedback? Any other bikes I should consider. I really have a strong preference for a bike I can buy locally with support and service if needed. Thanks!
