My machine came stock with 26" inch tires and 14" wheels. I would like to get taller tires. My question is how big can I go with no other modifications are 28" tires out of the question?

You can do 28s with no problem other then you will want to change the secondary's spring setting to B2 or at least C1. I think with the EX you can even do 30s with no rubbing issues. I have 27s on my 53 and they aren't close to rubbing anywhere but I did need to change the clutch.

thanks I will have to look into how to change that springe setting sometime I will be happy when the battery gets here and I can go riding I have missed out on 2 rides due to that issue
