How do these two atvs match up in terms of performance, suspension, and handling. Are there any big-bore kits for either of these two atvs?

 

I have a 2003 330 trail boss and my friend has a 250ex there pretty even bikes the 250ex gos a tiny bit faster the boss has alot better suspension, they both have about the same handling, the trail boss will get though more mud and is a stronger bike, my friend got his bike in april and by may he already has a bent axcel.as for big bore kits I don't no.

 

The 330 is a great bike and is way more comfortable than the 250. There are not many mods at this time for the 330 since it is a new motor. The 330 is a strong very relaible bike.
