I rode a bike while at my BIL's in Calgary. Nothing fancy, just an old Honda 250 cruiser. Took it around the block a few times, hit 4th gear. I don't have my license, and the bike didn't have plates, so I couldn't go further than that, but I think I'm hooked. I'm going to have to start looking at getting my M license, and looking for a cheap 500CC motorcycle. A 250 wouldn't do it for me, not because it doesn't have enough power, but because a 250 doesn't have heavy enough springs to support a 190lb dude - I was constantly bottoming out on it. BIL says a 500 would be a perfect compromise of low power, yet big enough to support me.
BTW, my BIL has a beautiful Ducati Monster 1200 sitting in his garage right next to the 250.... He's no stranger to motorcycles.
