athena ajh 50cc vs 70cc?

ian /

Hey kids can you help decipher the major performance difference bewteen the Athena ajh 50cc and 70cc kits? Does the 50cc kit sacrifice low end like other 50cc kits? Is the difference simply a matter of rpm/mph gains? I have an opportunity to buy both and need help deciding.

Thanks
