Swingarm question, is something wrong here?
« on: August 26, 2015, 06:15:44 PM »
Today I removed the rear wheel for tire replacement and when I wiggled the brake side of the swingarm I noticed movement in the A arm pivot points and some up where the swing arm attaches to the frame that I may not have noticed before. It seems solid with wheel mounted and it's been riding fine, tire wear seems normal and this may be something I just didn't notice in previous tire change as I had a helper that did most of the work. I expected it to be solid with no movement. Am I wrong and the bike is right, is the movement normal? I have video I can send to someone if they wish to take a look. Trying to figure out if I need to order more parts. Bike has 26K

Mine did this also, when I put new tire on right before Sturgis.  I thought something was loose, or wore out, but bike rides, and wares its rear tire ok, also seems to handle fine.... although makes you wonder why there is some slop back their....

To add a little more information, the parts that I'm trying to describe that have side to side movement are the machine cast metal piece that the axle runs through and the brake caliper mounts to and the long rectangular bar (I think its called a torque rod) that runs from this bracket up to and mounts onto the frame above where the swingarm mounts.

  Thanks for your response, it does seem odd and I want to be sure it's normal. At this point I believe it is but would appreciate the collective wisdom of the group to make me feel better about it.

The links, wheel axle and pivots combine to make a box structure. When the wheel is removed, each component seems like it has a lot of movement or 'slop' but once the axle is back in the bike and tightened, again it becomes a complete box structure and is very robust. Nothing to worry about and all of these bikes are like this.

+1 Its been awhile. I've moved 1000 miles further away from you since I last saw you on the forum. Hope all is well with you. Is your rostra still working ok? Mine crapped out last year but I haven't had a chance to debug it yet.

Glad I read this.  Thanks for answering Brian and thanks for posting Mal - cause I'd be real concerned if I came across this on my own!  Can't recall having this situation on any of my previous bikes.

Probably all of your previous bikes had a conventional, welded, stiff (Boys!) swingarm. The C-14 is very unusual in that it has a four- bar rear linkage system; in fact, as far as I know, the only other bike that has it is BMW.

Well ****, I can't afford those.  Guess the C14 will be the only bike I'll have to know about this.   ;)
