RE: Radio Shack Dirtbike
my friend has one with a 12t orion modified motor and some other nice stuff in it and it is very fast and seemed to handle good. we took it on my dirt bike track for my real bikes and it was pretty cool...it didnt clear the jumps but it was pretty cool. my track was just groomed so there wasnt any rutts or anything....but with that motor and stuff it was fast. on the street in had to do atleast 30 or more..my friend did say he had to make some custom parts b/c of the motor...he also hasnt had any drive train problems yet...
