To much bike for a second bike?

The Rocket is the craziest stripper at the bar.
Most of the other girls are prettier, but nowhere near as fun to ride.
If you treat her wrong, she'll cut you.
The best way to have a trusting relationship is with a long courtship.

The fact that you recognize the importance of respecting the bike says a lot about whether you're ready or not.
 
I think an r3 is a fine step up as long as you know your limits and are prepared to be patient learning the bikes limits. In any case ot is probably a less risky upgrade than a litre bike
 

Entirely different riding experience. Your looking at the most powerful production bike made. Regardless of the model you interested in, marvelous for travel and exploration. Daily city CAN be a challenge because of its size, not will, but can. I had a classic and made the mistake of encouraging my wife ride it around the block. She now has an R3R. Her street triple gathers dust... My 2C, your riding skill and comportment will gain on a Rocket from the YZ. The biggest issue and ego is, is it too big to safely handle.
 
My son had a few years of riding under his belt, but not near as many miles when I got mine and he does just fine on it. He just had a Street triple. If you ride one and feel comfortable, don’t hesitate. Just respect it. I rode one and ran around with a stupid grin on my face every time I thought about it for five years before I got one. That was five looonnng years lol.
