looks like you changed your mind since last thread edzy.
depends on how the thumpstar is and what condition it is in. check all the usual stuff like bent frames or cracked paint showing stress marks. also if you look at the pegs and they are tilting down than you know it has been jumped and could possibly be weakened. another thing you can check for is large scratches on the bash plate as this would indicate casing on jumps. but if the thumpstar looks good and is only1200 than i would go with that otherwise the pitpro is a great bike.
