So.. many.. articles... here... already... same... subject...
Sorry- you can tell I tried to hold it back
I'd personally say that you're going to want to get some more experience before taking a passenger. A month and 800 miles doesn't lead me to believe that you've experienced anywhere near the full gambit of situation solo, let alone with someone else's life in your hands.
When you do decide to take your first passenger, it's best to have it be an experienced rider in a less active environment so that you get used to the difference that 110-250 extra pounds makes and so you don't scare the hell out of your first passenger
When you have a passenger here are a few simple rules to live by
1.) Don't be a jerk- ride more conservatively.
2.) Explain some rules to the passenger to start
a.) Don't mount the bike until you say it's ok
b.) Don't dismount the bike until you say it's ok.
c.) Don't take your feet off the pegs until you dismount even if you think the bike is falling or at a stop light
d.) tell him/her to look over your inside shoulder in a turn and to lean with you. Explain that by not leaning the bike won't lean and the bike needs to lean to turn
e.) Tell him/her not to move too much if at all, and especially no sudden moves so as to not upset the bike's path
3.) You will need to use smooth starts and stops otherwise your heads will bang together or you might leave your passenger sitting on the ground behind you
4.) Both of you are geared up (way to have that taken care of)
5.) You both understand that m/c's are dangerous and that both lives are in your hands
I'm sure someone will add something that I missed
