Swingarm is that silver ano part with Atlas sticker on it.Thats where the difference between old and new one is.It seems that on blue Joker has old type:more simple desing,front of the swingarm is straight.Compare pics.
Yes, Pro's joker looks like the older version, which is what I had. Same color scheme too. My joker did not break, and it did ride allright for a high single pivot. The price seems fair, but bear in mind that you will get no customer support from the manufacturer iif it does break. Not trying to start a pissing match; you are not the original owner, and they probably don't have any replacement parts left.
