started riding in college - saw a small dusty Honda 125cc in the back of the shop my friend was dropping his car off at for repairs. it worked, it was cheap, it got around 80mpg IIRC. That's why I started riding. Even got my motorcycle endorsement - eventually. Kept riding because it turns out the freedom is exhilarating. Had a couple of little Twin Stars, then sick of them always breaking tried one of those new fangled sport bikes (NINJA!). Got a used 500cc & the thing just always worked & I find sport bikes to be really comfortable. The power of the 500 over a 125 was intoxicating as well. Right now I consider myself between bikes (20 years now - LOL), but still have the endorsement on my license. Every time I hear a flock of sport bikes something primal yearns inside. Been having a strong hankering for a BMW 650 GS.
You might have noticed a small bike theme. I'm tall but not heavy, I like a bike I can control. I've had people pull out in front of me & ended up skidding sideways, but I kept the bike upright & managed to drive around the dummkopf. I think it's important to be able to physically overpower the machine. Truly a matter of life in death.
HOWEVER - just know you will be invisible & drivers are more distracted than ever. I sold my last bike after several near crashes with distracted / lost / confused drivers & that was 20 years ago. I do still think it's worth it, but riding safe is really very exhausting, far harder than any technical skills required to master a motorcycle. But so worth it. Start with a used bike so it doesn't hurt so much when you do something stupid & end up dropping it (like kickstand on hot pavement on a hot day - softer than you'd guess!)
Wear a great helmet. So much cheaper than rehab.
