AOA fellows here is how to secure helmet using Studds helmet lock.
this lock comes with 4 pcs of nuts and bolt that are design to fit in their position in such a manner that no 1 can tempered it our open it without using special tool. in my case i lost 1 of the bolt in installation so i decided to install this lock using LN key bolt and nuts and it works perfectly.
also with this lock come 4 pcs of specially designed rubber which is very usefull in order to fit on different dia of installation pipe. for gs150 newer model 3 of the rubber pieces is needed as for the older model 2 pieces are enough.
key for the lock is also some thing different. i wanted to have a 1 separate key make in case i lost 2 keys supplied and to my surprise lock smith took nearly 20 minutes to make the key and that too was not up to the mark :D.
so it got safe locking system.
material used in the lock is also very good also unbreakable, very good finishing.
overall its a 1 fine piece of accessories required in order to lock helmet on bike.
so here are some pictures i took today morning.
take care and kind regards.
