If anyone knows any information on this model It would be greatly appreciated if you could share it with me. Just the usual, hp, top end, comparisons, and so on. My guess is 67hp at 85mph.

Thank You,

Panasync.

panasync,
*i don't have any hard information to share but my son has an mxz 440 and it will ring 135 kmh which is close to what you are thinking the 03 550 will do. the new 550 is an H.O. engine so i think it will be a good all around toy.
