I'd suggest against getting this bike until you learn the basics. If you had a little experience, this bike would probably be just fine for your weight and size.
People have learned how to ride on these sorts of bikes before, but I don't recommend it. If you aren't ready for the power, are unused to shifting, and accidently drop the clutch, bad things usually tend to happen.
If it has too much power for a rider that has experience, it's not going to be the best choice for someone just learning to ride.
Hold off on your purchase, and ask your friends to let you try their bikes so you can get a little saddle time before you make a commitment. This way you'll have a much better idea of what fits your riding style.
Lastly, make sure you budget for gear! This includes helmet, goggles, good quality boots, and chest protector at the very least!
