So I am back to report the findings I saw with the chrome swing arm from Treats.
#1- no noticeable difference from the old one while cruising on level ground
#2- Light turn around a few S curves proved to be about the same as before traveling at about 35 mph. Slight, slight notice of back end is stiffer...maybe from new 280mm shocks
#3- I put 280mm shocks on thinking it would lower the back end, but it seems the new swing arm suspension connections seem to be higher than the stock.
#4- the BIG one. I took a corner going into my driveway REAL hard going about 35mph and I thought I could feel a little sway...so I did it again and I did not feel it again. I did some quick zig zag patterns and found no problems.
I would assume that since my bike is not kitted and no port work that it is sufficient for speeds and cornering less that 40 mph.
