Motorcycles are dangerous. I drove street bikes for over 20 years, managed to break a big toe, but had lots of close calls. One problem is that if you don't ride on a regular basis you loose that that edge that keeps you alive, the edge being aware of road conditions and especially cars. As I recall the accdent rate is very high for the first year and then drops off kind of quickly.
The classic accident is a car pulling in front of a bike because 'I didn't see it' or because they don't care (they pull in front of my 3/4 ton pickup so I know that they don't care), the bike rider stomps on the rear brake, the rear end breaks loose, the guy does down and slides into or under the car. I practiced HARD shutdowns from 120 mph and above on off ramps, to keep it instinctive and to make sure that everything was working ok. You learn that it's all front brake in a panic stop.
The safest spot for me was in the #1 lane slowly passing traffic, but it also meant that my points were always maxed out.
Older guys buying their midlife crisis Harleys are in a bad spot as they don't always have the reflexes needed to stay out of trouble, and when they pack it up they don't heal as well as younger riders.
Wear boots, pants, gloves, leather jacket, and a helmet. Dirt bike riders get in lots more accidents, often the weekend ride ends when run out of parts to replace the broken stuff, but typically the accidents aren't as bad. The best street riders started in the dirt, and then moved up in bike size as their skills improved.
I do love bikes. My now antique stock 1983 Suzuki would do the 1/4 mile in 11 flat, 0 to 60 in under 3 seconds, for less than $3000 new. I typically got 45 mpg with regular not quite legal driving, and put over 80k miles on it before it was stolen. The liter bikes these days run 10 flat in the 1/4 mile and top out up to 190 mph. But I don't know if I'll ever get another, and now have as 'vehicle fun' with my diesel pickup.
