BMW S1000RR shock setup

[kebab19]

Standard BMW Sachs spring is about 170mm long and spring rate about 475lbs, which is barely enough for solo riding unless you're a bit of a stick insect.  Cheapest option would probably be to fit the standard spring from a 2006 onwards R6 shock as the spring is 165mm long and the spring rate close to 550lbs, so would cope better with more weight on board.
