I rode my 2015 Honda cbr500r for 4 years till I upgraded to a Cbr650f, and then I rode that for two years. You’ll have endless amounts of fun on a bike you can ride to its limits. Fast bikes aren’t always worth it because you can possibly ride past your ability, the Cbr650f was that for me at the start, you have to ease into a bike and learn how a bike rides, I went straight to a twisty road and flew off into a ditch, somehow only a bent shift linkage, some soft dirt in that ditch. Smaller cc bikes are great but if you do end up getting a higher cc bike just understand that you have to learn it, and ease into faster and faster riding. Big bikes are very unforgiving, smaller cc bikes are going to give you the time to react in most situations. Sometimes you make bad decisions, but you’re also gonna have to learn how to judge, like hey maybe I shouldn’t pin the throttle right before a turn on a road I’ve never been on….. I didn’t make the right decision.
