Seat time
I have no doubt the arm will hold up for me. Not a pro stock bike! With my gay extensions I could cut a 1.47 60 (only ran them one weekend), hoping with the new setup and pracitce to get 1.40 or less. At least with a few runs under my belt. Oh and thats with original clutch plates at 7,000 miles! The reason for the extended tail is that I still ride it on the street, nice to carry crap in the big trunk. Oh, and it will now hold a 3lb bottle as well ??? Justin I think the arm was 760 with everything shipped, 3 hole, bottle mount, chain guard. I failed to weigh the swing arms, I was in a hurry for a bike night after work. I momentarily held each in hand, POSSIBLY thinking that the new arm was about identical if not a hair lighter than the stock. Definitely lighter than the stock arm with the extensions I had! Hope that answers all the questions. Thanks for all the comments guys, I appreciate it!
