The 1/5 bikes like the TT are better suited for street racing, and handle better then the smaller 1/8 Venom GPV. The Venom is great for Nicely paved lot like a tennis court or similar surface, doesnt handle the street very well, one small rock sends the bike into a violent crash.

I like 1/5 scale, and there is probally more aftermarket parts for the TT than the Venom. Plus its easier to learn and drive a larger bike than it is a smaller one. Just my opinion.
