Swing arm shenanigans.

I put most of the information about the fitment in the other thread about the Swing arm posted by PeaceSportsAtlanta found here: http://chinariders.net/showpost.php?...3&postcount=22

What I want to cover here is related to the shock and the effect on the length if the mount point on the swing arm is used.

What will need to be done comes down to two things.

The easiest/cheapest solution would be to drill a new pair of holes on the bracket to put the lower shock mount in the same relative location as the Hawk arm - roughly 20mm lower than the current holes. The good news is, there is a lot of bracket to work with for doing this, and the excess can easily be trimmed down.

The more expensive solution would be a shorter shock. Now, since I didn't feel like completely tearing down the bike to fully remove the rear shock, this is just guesstimation work, but should be fairly close. If you stick with a 320mm length shock you would be looking at at least a 2 inch increase in ride height in the rear. To achieve close to the stock Hawk ride height you would want about a 25mm shorter eye to eye length shock - aka 295mm.

Going back to my previous post concerning myself considering a Fast Ace shock, I have been eyeballing this guy: http://www.pccmotor.com/fastace-11qu...280661001.html

Preload, compression, and rebound adjustment with a 70mm stroke - compared to the 40mm of the other generic shocks of the same length.
I would have to trim a bit more away from the air box to clear the reservoir, and getting to the compression adjuster would be mildly annoying, plus the cost is a bit more than I would like to spend.

The other one I have been looking at is this guy. https://www.amazon.com/280mm-Fastace...gateway&sr=8-3

Slightly lighter spring rate, but also has the same 70mm stroke.

The second option is more tempting just for the simplicity and the cost. One nice benefit of the brozz mount bracket is that, if the 15mm shorter shock lowers it more than I desire, I do have some room to work with on changing the mount location to bring it back up a little bit if desired.
