New to the Game

I want to start riding bikes, not a total novice but not enough to make me a rider. My question is for someone starting out should I start with a 600 or can I learn on a 750 or 1000, all Gixxers

Depends. It really comes down to your size. You should sit comfortably with two feet on the ground when at a stop. If you're light enough, a 600cc may be all you ever need.

The standard advice is for a first time rider is get a bike that you won't cry about if you drop it, like a used one that you haven't put big $$ into. My first bike was a 750cc, bought new, and it was not a wise choice. Young, dumb, and, well, we all know the rest. Wear the protective gear, even if it ain't the coolest look, at least for the first 5,000 miles. No matter the bike or the rider's skill, we tempt death every time we ride. I've known a few riders that didn't make it to 5,000. You have to be ten times as alert as a car driver. That thrill is one of the reasons we ride, but it is not for everyone. Learn your skills, and be patient before trying to push your limits.

Slow speed figure eights in big parking lots is a great way to learn the balance and feel of your new ride. Do 'em till you're bored, then do 'em again. And again. I still do 'em a few times a year, and been riding since 1979. Take the riding training, it is available everywhere and is the best way to get started.

Good luck, and keep the shiny parts off the road!
