If you could measure an SR and RD swingarm and post the results, I am sure that would help a lot of people.

I will measure pivot bolt centre to axled center, pivot width, widest width of swing arm and narrowest, over-all length and pivot bolt size.  I think that should cover it but I won't be able to get to it until next week.

Again, the Motolanna swing arm is gorgeous!

The RD Swing arm measurements are in the above thread.

“Ds7,r5,rd250,rd350, rd400, twin shock dt250

total lenght 18' + 1 1/2 inch for rd400 + 3 dt250
7 13/16 axl spread
7 9/16 pivot

All rds except the 400 run a 17mm axl but there is a 20mm bushing on the sproket side so the axl plates are different left to right the all the dt250 & 400 ive seen are 20mm on both sides

for all the above bikes the pivot bolt is 16mm as is the frame”

Sorry for the delay, I was not able to get up to where my SR500 is strored.

Stock Swing Arm Measurements:

Swing arm pivot centre to axle centre in mid adjustment position - 18.25"

Pivot Width - 8.28

Axle Inside Width - 7.25"

Let me know if you need more measurements.

You can see that with the Motolanna swing arm that there is very little room between the arm and the passenger peg mount, about 1/8" on the right side and slightly more on the left side.  I haven't yet figured out how I am going to mount the exhaust because it was mounted to the passenger peg mount.
