PICK A ROSSI FOR ME
 

ROSSI PLUS 21-5K
ROSSI 21P5XST TURBO HEAD

It really depends on you and the tracks you will be racing on. The p5x has more bottom end power, if your experienced and race on fairly godd traction tracks go for it. If you have a Truggy definately the p5x.
If you race on slippery tracks or are not as experienced the 21-5k is smoother on the bottom and has a bit more top end.

Hope this helps.

Axe Rossi Cobra with JP3 or JP4 pipe is really value for money for a good bottom and top end power.

Axe Rossi Cobra X1 Evolution (turbo plug) for even more bottom and top end power ;)

P5X Go with that one.It would do everything I asked it to...It has gangs of bottom and is still super fast on top...
