I currently have an 04 crf 450 and am ready to get a new bike. The MXA review said that the Yamaha was very reliable yet lacked low to mid power. The reason I would overlook this negative is the reliability and suspension/handling on the 08. Is the power issue fix just a simple slip on exhaust and new jetting? If so I think I'll go blue this time and ignore the "Test Riders". Thanks for any help.
