People judge by their experiences with companies, yours was positive with hyperpro mine was negative. I spent 600 quid almost on springs and a shock for a tiger 1050 which completely messed the bike up. The fork springs were 285mm and oe is 300 so too much sag and the shock was 4mm to long thus given a axle height of 12mm over oe, the bike was unstable at anything over 80. I removed all and sold it, fitted ohlin's and that did transform it
