I am running this thread on a few other bike forums and this is what I have so far.
1. Show respect to your fellow biker as he/she may have travelled many a road.
2.Never touch another bike unless invited to.
3. Never criticize another bike; it may be the best that can be afforded at the time.
4.Try to acknowledge the other biker on the open road. This just show that you share the bond of being out there in the elements enjoying the moment.
5. Be courteous to other road users. This includes acknowledging drivers/riders who give way for you, as well as giving way for other riders/drivers who have the right of way.
6. Make way for faster vehicles, let then past in a friendly manner.
7. Never pass another bike or motor vehicle on his left hand side unless he indicates for you to do so. Keep Left and Pass Right. The opposite being true for the USA.
8. Always stop for a bike on the side of the road. He may need help, if not well it was worth the effort and I am sure it was appreciated.
9. Don't pass other riders on the inside of turns - you never know
if he/she is a newbie, nervous etc.
