In order for the Ruckus to be a viable option for me, I need to be able to hit 50 with a relative quickness and be able to increase to 55 if needed. I'm also 230lbs. For the stock 50cc GET to get up to those speeds it's fairly expensive.

And if push comes to shove, I'll get a Taiwanese B case for the GY6, from what I've read they seem to be a heck of a lot stronger than the stock cases.
