I've got a Nitron on the back of my ZX-14R. Very nice bit of kit. Super happy with the shock itself. Just have to lower the rear ride height a bit, not so much for handling, which is great, but for sound ergonomics. I have a terrible buffeting issue from raising the rear height too much, and it has most certainly given me some hearing loss from it. I ride with plugs too. 10 of 10 would purchase again for any bike I ride.
