im making my own extended swing arm out of a stock swing arm and some flat stock steel... i just want to know what size i should go with? i was think 2" just so i have a little extra traction and doesn't look to big and wont make it hard to turn. i do a lot of trail riding.but what i have been reading a lot of people say to go 3" i just want to know what everyone thinks...ill make a post of the DIY swing arm when i start.
