I was reading the taking your children riding thread and wondered when most of you took your first passenger. If I remember correctly BCSC recommends 5,000 km after you get your Class 6.
I think I carried my first passenger at about 15,000 km and have over the years taken most visitors to the house for a ride if they asked.
I have rules (of course) full gear and we leave alone without the family watching. I give them a 3-5 minute talk on being a passenger and general MC safety and we practice the mount/dismount while the bike is not running first on the centre stand and then not running off the stand.
When we return the family can take all the photos they want but initially I want the passenger to be paying attention to me with no distractions.
One day I was stopped every ride for a license check, this became the ride highlight and the last few nieces got photos of us stopped
