Thanks Steve. I see you chose the black spring.Hi Martin, I've tried to attach a photo - no idea if it's worked until after I submit this reply though. In summary the shock is excellent quality, it comes with a special tool to adjust the preload with too. I recommend putting some silicon lubricant onto the threads first (before installing the shock) to make it easier to adjust.
Installation was ok to do, I used an Abba stand to support the bike and this enabled the swing arm to be moved easily once the shock was unbolted and this aided the removal of the unit by dropping it downwards. I managed to do so without dropping the exhaust - but it's a tight fit. Actually installing the new Nitron was quicker to do than removing the original.
I had the suspension set up for me by Dave Moss who is in NZ at the moment, after a couple of runs he got things nicely balanced.
The bike now handles as it should - holds a tight line through the bends, it has a real quality feel to it.
I was looking at the cheaper Ntr1 shock without the remote canister.
Anything has to be an improvement over the stock shocker.
They have ride height adjustment.....did you raise the rear?
