I need new rims for my build regardless of how I go, so I'm wondering what are the pros and cons of going with 12" rims vs. going with 10" rims again with larger tires. I currently have the stock swingarm, and have thought about a new one, however there is nothing wrong with my current swingarm. Is this something else I should also consider? I'm pretty settled on putting a 150cc motor into my build. Will a longer swingarm help anything other than tire selection?
