Hi, just bought a 3125R, it's a pretty fun little bike for my kids (& me )

I see a lot of folks upgrading the stiff front stock shocks, but it seems like almost everyone is getting 320mm shocks - from what I can measure, eye-eye, it looks like my current front shocks are ~280mm. Does this sound right? Are 280mm my only option for this ATV, and if so has anyone found any at 280mm that they would recommend? Thanks!
