This conversion kit will fit ktm 2016+ 4stroke linkage bikes and 2017+ 2 stroke linkage bikes as well as all husky 2016 linkage bikes with the large bladder. This kit replaces the stock piston type reservoir and turns it into a bladder type reservoir for much better square bump absorbtion do to the lack of friction normally associated with a piston type reservoir. The larger volume of oil and nitrogen allow for a more consistent fade free shock. The other benefit is that it uses a standard kayaba shraeder valve for filling with nitrogen. Using this kit will make servicing your shock much easier.
