Tire Size

Hello Everyone, I am having my stock swingarm for my 77 KZ extended 3 inches, My question is does anyone know what the largest tire size I can put on it would be??? 16 inch LTD style rim, tryin to keep rear LTD style fender on. Thanx, Shaner

Probably a 140mm tire. You are limited more by the rim width than the swingarm now. A rule of thumb is you can go up one size wider on any rim and still be ok. You can go more than that but you'll run into issues with handling/traction.
