I have had Nitron tvt fork cartridges and ntr1 shock on the bike for a month now , and am really enjoying the ride they bring.

First thing I noticed was that the headlights were low due to the bike riding higher at the back,or more correctley not sagging at back.Second was front tyre picking out irregularities in the road surface,running on road 6's ,a drop in front tyre pressure to 30 psi from standard 33 psi sorted that.Grip is great along with confidence the bike isn't going to do something uncontrolled ,this is probably the best balanced bike I have owned or ridden, certainly the best in the wet,and pushing my KTM SMT990 hard for control overall.
Comfort is a personal thing but with the nitrons fatigue is lower because even at normal road speed it is so easy to turn and corner it takes nothing out of you.The front, with a separate valve for compression, rebound and high speed compression[this last one is the most important as the standard forks have little control over this] smoothes out bumps while remaining level.
I had already fitted HH pads to the front brakes which helped with bite ,now it's like I have gone another level up ,grip and feel under heavy braking is readable and easily modulated.
Hard riding still allows the bike to move around a bit,I have dialed that out but lost overall feel/grip so put it back to previous settings, long travel suspension will wander in extremis but feel is more important to me.
I got all this from MCT suspension near Stowmarket,Darren there is a damn pro and will recommend him to all. Price all in with Darren's work was£1500 ,money well spent.
