Question
I wanna put on a wide fork on my sporty..what years do I need to look for in used and what about a big/fat on the back....less than the 1,000's Have seen advertized. It's my basket baby. thanx richard

Answer
If you want to put a wide tire on you will have to either modify your swing arm or locate a wide swingarm so you can make the tire fit.
In order to put a wide front end you will need a triple tree from the 70's up to 85
Good luck and happy riding
