I have aways ridden Yamahas as race bikes from my 1974 MX250 to my current 2006 YZ250, but I have always ridden Honda XR's for off-road/dualsport/Baja use. I am seriously considering a new leftover 2005 WR450F as a dualsport bike, but here is the deal... Our rides are fairly extreme, typically 250-350 miles per day (usually about 8 solid hours of running time), for several days, mot of the time in very remote areas. Sometimes we go down to Mexico and ride the entire penninsula and back, about a 2600 mile trip. Here's the most recent: http://www.advrider.com/forums/showthread.php?t=369729&highlight=cedarville The bike is always fully serviced after one of these rides, however there is little opportunity for maintenence during the rides. So, does anyone have real experience with the WR450F with this type of riding, with upwards of 10,000 miles on the clock? Thanks, I appreciate your objective comments in advance.
