Coming across as a bit breathless there.
It’s dangerous, but lots of things are. Driving a car is dangerous too, especially for a new driver. If you assume that all the other drivers are not paying attention you’ll live a lot longer. My car has been hit twice while standing still, by people who didn’t have their head in the game. I now drive and ride the same way: assume that the people around me are oblivious. It’s saved me from ugliness a bunch of times, both on two wheels and four.
Take the training, then spend a lot of time practicing on -your- bike, especially your low speed stuff and evasive maneuvers. This is the hard stuff that will trip you up, get you injured. Your bike will handle differently than the bike you learned on in the training class. My 750 is a whole lot more resistant to turning and swerves than the 125 I learned on, so I had to relearn how to do all that. Not that my bike isn’t nimble, but I need to commit my body a lot more to any maneuvers.
That, by the way, is one of the very good reasons to buy a smaller bike. I definitely need to think out what I’m doing faster and further ahead on my 750 than I did on a smaller bike. It hasn’t undone me yet, but the potential is there.
