I like to have an access to better MX tires that is why I keep updating all my bikes with 19" rims...The question is: If I add some 3-5mm to overall redius/diameter of the rear rim, shall I adjust the shock lenght accordingly (to make it shorter by ?? some mm.)...what made me think of reducing the lenght of the shock ,even not necessarily for other reasons besides this one, was the recent experiments I did to my KTM 530.....reducing the shock lenght by some 2-3mm made a huge improvement to my bad suspension?.....I like to keep an eye on the small details.. :evil:
