you need 52s in the front and a 95 on the rear. the plastic spring guide on the front, the square thihng like a dog chew needs filing down as the 50+ can only be fitted with its fatter wire when the 4 high points are filed down.
just borrow a 'body filler plain' from a car workshop. an hours work.
because the 570 is a heavy bike, you have to weigh the springs for you AND your heavy bike. defo a 95 on the rear and even then ++ because the LDC 70d engine is very heavy on the rear as well as tyou as well as the overall bike.
