Greetings from the (not so today) sunny climes of North Texas. "Big" is relative, my Thunderbird Storm outweighs my Rocket GT and has about 60 less ponies to push it around.
You ordered the Rocket Storm GT, I also have a new model '26. No worries about riding how, it does'nt ride heavy at all, it is very easy and light riding, you'll be positive surprised. Also with rain or in curves stabel. Within a minute you can get the hang of it. ok?
Welcome from Michigan. The weight will melt away once your going and the power band is above 4000 rpm so its not like its just going to explode with uncontrolable speed. It would kill me having to wait for it though.
Your going to enjoy it. Also you can move the forward pegs an inch in each direction which makes a difference so keep that in mind. If your on the shorter side you might like mid position controls better. Good luck with your new bike when it comes.
