Re: Featherweight ISO sport bike advice
I think you will fit fine, i'm also 5'10", but 190lbs. My previos bike was a y2k 400ex, and now I ride a Raptor. The 400ex has more than double the power of your 300ex, my wife had one of those. How much can you spend to compensate for your light weight is the real question. You can handle the 400ex as is, you might consider at least a swingarm extension for the Raptor. My fat a$$ can keep the front end down most times, but not always. The Raptor is fine for trail riding as is, that's what i do mostly. Good luck on your choice, both bikes are excellent choices.
