I ordered the spare bobbin head to replace one on my bike with a minor abrasion on it, these things really work and saved me a fortune when
my bike rolled off it's side stand and went over... I felt utterly sick at the moment the bike went past the point of no return, it was an unfortunate
accident but the bobbin stopped the tank, fairing and tail getting any damage at all - no marks / dents or scuffs.
The only casualty was the end of the clutch lever - do yourself a favour and get a set of the bobbins at the front and rear of your bike, it's a small outlay for what could cost thousands without them.
