Hi, new to forum. desert racing and GP racing senior class,(not competitive)Which bike? Does the 450xc have more updated suspension,or other latest tech? I currently ride CR 500 & xr 650 so I like big bikes as easy and lazy to go fast, but other riders have advised me to go xc450 vs xc525 as plenty powerful but much better handling agility? and better suspension. My dealar is selling the xc 525 $300 less than xc450, as the 06 525 is not so popular this year, so I am tempted to maybe buy the wrong bike?
