Thanks for your input man.Honestly I would ride safer on a 1000 than I do my 600. 600s are very fast but because of the torque curve and gearing, the only way to tap into the speed is to.. well... speed lol. The power doesn't start until you're over 50 and then only in first. On more torquey bikes though I tend to get my thrills at lower speeds. That said, a liter bike has much more ability to break traction and that is definitely a risk to think about.
You know what's funny is the first motorcycle I owned was a trade I did for my car. I never rode it but up and down the driveway. I was way too intimidated by it. It was a GSXR 1000. The throttle was SO sensitive, you just barely touched it and it would take off.
At that point, I hadn't taken the MSF course yet because my parents didn't want me to get on a bike. So I was trying to respect their wishes.
But like two months later, I took the MSF course and got my 250. I couldn't wait any longer.
After riding the 250 as a daily, I went to my friends house one day. He had a GSXR 750. I rode it around the block and the throttle response wasn't much more than the 250. The transition was easy.
The 1000 even sounded intimidating, haha. It had a full exhaust on it.
