Mornin' bloodbikes et al,
If, like the dealer in NSW you too reside in NSW where l believe annual vehicle inspections are required in order to re-register your ride, l strongly suspect these friction locking device will make your ST unroadworthy

Though we in Vic dont have to paticipate in anual inspections (yet), we nevertheless come across the odd police trafic operations mangement task force with VicRoads inspectors in tow and have read a tale of an interrupted Sunday ride due to a throatle friction lock. So would NSW (or any other state), for that matter be any different

Either way, reckon it'd be niegh impossible in stopping half a ton of ST1100 in an emergency with 2 to 4 thousand revs still wanting to propel ya forward.
Just a thought.
Ciao the can:-)
