Hello, I am tempted to sell my WR450 a get a YZ450. I know the suspension is harder but i like to ride my bike on MX tracks and trails and the WR suspension is not very good for mx and i have already blown the rear shock and the fork seals have blown 3 times in a year. I have a talon 18" rear wheel so no worries about the tyre issues as i will keep it for the new bike. What apart from the 4 speed box will be not as good for trail riding on a yz? Can people give me some pro's and con's for each bike please?
