yep, they are a waste of money. Bought mine off a mate who wanted rid, from his GSA. Didn't stay on my bike long.
Other crap since removed was the locking oil filler cap.
Crashbars weren't replaced after a 30 / 40mph "off". Rocker box cover was holed, as the crashbars folded too easily. OK it might have been worse without them. But, the inconvenience of the extra width in the garage!
