I had a chance to weigh some different weights today, don't know how exact my scale was but this is what I found.

360 45g

700 55g

I tried the 360 weights in the 700 and couldn't tell much diff, I didn't have a stock one to race with though, oh ya I also installed a EPI spring and set the belt deflection.

 

Are they the same curve/shape?

 

Yeah, what Nova said. Will they fit in a 650?

 

Sascach,
I think I might like to try a set of those 360 weights, the clutchs are the same from quad to quad so I will call you let you know.

 

The weights do not have the same profile. But the bases where they bolt in the clutch are the same so the fit just fine. The 360 weights have a bit steeper base than those of the 700 but I didn't feel any weirdness because of it. After I started this thread I went and put the stock clutch on and I think I could feel the mid range was better with the light weights. Might try it again today and pull a new one out of the show room to test it against.
