going from a 05 YZ250F to a 09 YZ450F in the woods

the 05 yz250f was a dream on the trails, might be picking up a 09 YZ450F wondering what to expect, if they feel heavier, less maneuverable, better low end, etc.

I love my 09 450 in the woods. It will feel heavier and the hp will be more physically taxing but I bet you will be shifting less and loving the uphill grunt. The extra weight is well worth it for me.

Gytr heavy flywheel worked wonders for stalling and traction control.
