The NewGen rear shock has a very decent spring, and valving isn't half bad for street use, it's a popular upgrade for the PreGen, and the EX500.

On my PreGen I went with the ZX6 shock, it's nice to have the air adjustment, comes in handy for two-up rides. I did it before I knew about the NewGen option.

If your into a more spirited riding, and you money is good, then aftermarket it is, but if you were satisfied with the OEM shock, then stick with that, and look on eBay.

Something else to keep in mind is, if you change the rear suspension, then you'll also need to do the forks to match to get the full advantage of the suspension.

Don't forget to set the sag.
