^^^ Go to Tony's Cycle...or MotorSport Plus.
Tony's is on Bath road in the "township" . . . . accross the road from a 1970's looking highschool.
MSP is on the opposite end of town, inbetween Sir John A and Division...running parallel to the 401 (you've probably seen the HD / Honda sign if you've been on that strech of 401).
Backroads: Go out Bath road to Tony's, have a look and keep on going past Amherstview. Although better roads (IMHO) are better ridden out #2 hwy. That's the road that goes inbetween Fort Henry and the Royal Military College. . . . Once you're past the base, it's open roads, and many back country roads (Abey Dawn road is 5 or so kms long, but has a nice twisty in it).
Another IMHO, it'd be safer for a newcomer to ride with a friend or two...get a guided tour around town, and keeping safe in packs. I know i just cruise idely along in the city.
Good Luck !
