Test drove 21V Launch this summer and finally bought Yesterday. I knew I needed to upgrade bags then, so what should I do now? Stock 400's in rear and I think 750 frt. I was thinking 1100's at rear. After reading up I will re-inforce compartments at bottom sides. Do I need to worry about fibreglass piece coming from top side that run's length of the bag? Obviously it sounds like I can't fill to 1100 but I don't want bags on seat.So will 900-950 lbs(80-90% full bags) do it ? What about my stock 400's . Can/should I put one in front. If so can I tie it in with front plumbing?
