I know right, me either....Rotos usually give a bit on the rear axle mounts when you pull them back. This is quite Rigid now, with a little flex in the bars and some dampening from the wheels.
I reakon this may have saved a lot of cracked base brackets, as its not constantly bending them up and down.
I really love the ingenuity of some owners...The pink stocking on the air filter was a nice touch...lols
