I went to my vespa shop to buy a front wheel lock that attaches to the brake disk.
Unfortunately they were all out of this item.
The sales guy told me it was useless on a small scoot and just use the steering lock.
I said it does not work on the S50. He showed me on an S50 floor model and sure enough it worked!
Went back home tried it but can get it work.
So how do I lock the steering of my vespa S50?
