I used to race bikes on an amateur level. Started on dirt bikes when I was 11. My first street bike was a 500, first superbike was a 600, then a 750, then went to liter bikes. I went to tons of track days and spent hours and hours learning with control riders. It was a very long process getting to the point where I felt comfortable hitting the track. But I was safe, never felt out of control and even on the street was a fantastic rider.
On the other hand, I met plenty of people who bought a liter bike for their first bike. They were horrible riders who often had very little control over the bike and couldn't ride for squat. We called them squids. They were a danger to themselves and others, and despite "thinking" they were awesome, truly had no idea what they were doing. Put them on a track and it was like racing a child on a tricycle. I used to love watching someone on a 600 smoke a rider on a 1k that thought they were "bad to the bone."
It was also pretty common to hear of the terrible accidents these squids got into, often times resulting in the loss of their lives. Simply because they thought they were the world's gift to riders and truly had know idea what they were doing. They didn't know their limits and because of it exceeded them often with disastrous results.
The point is.... Take your time. Research and learn. Take small steps. When you're ready for your next step, whatever that might be, you'll know, and you'll know exactly what that step you want to take is. In the end your vape experience will be a fantastic one.
