Almost half of all single-vehicle motorcycle fatalities are the result of failure to control speed in a curve and running off the road (they told us in MSF class).
That's a littler harder to do at lower speeds on city streets. It's more of a high-speed accident category.
70% of all motorcycle accidents are the result of impact with something between front-right and straight-left. People turning left in front of you, or crossing your path from your left, mostly.
Which means the danger is there if you're (a) not skilled at making curves at your chosen speed and (b) not skilled at planning defensive and evasive actions in traffic.
MSF class will help with both. And will get you your
M endorsement, the lack of which is associated with the majority of motorcycle fatalities. So the real danger isn't just on the road, it's also in your pocket.
Addendum:

links to data showing that the
vast majority of motorcycle accidents happen to people who did not learn to ride from professionals. Frankly, armed with that knowledge, I'm willing to start lobbying for laws that mandate certified training before getting endorsed, and huge, well-publicized penalties for riding without an endorsement.
