I just got back from Iraq a few months ago, and told myself that if I made it back I'd buy my Bonneville so I did. Now I need help because it's gonna be here soon. It's a 1973 with a 71 650 engine. What size axles does a Triumph use? Also It has an oil in frame body, but can I use a david bird hard tail on that frame? Any all info no matter how small or big is appreciatted.
