Cheers, finally some suspension talk. Have a 2019, 15.5k km's on the clock. Got redirected here from tenere700 forum and thankfully, already subscribed here.x Around 80kg rider, first went for the 8.5 k tech spring, which I now swapped with 8 kg, zero preload, as like topic owner said, it is 245mm long so already has plenty preload when installed. my yt video. While making multiple purchases of various springs, I have an unused k tech 9 kg, brand new, never mounted spring available if someone interested, misorder. Also got a 50€ k tech shock kit installed, valve + both stacks, which is "compatible" with springs 8 - 9.5kg. Oil used was kyb k2c, basicly 2.5W shock oil. Stock N pressure was 6.5 bar, k tech data opted for 10 bar, so filled with 10. Currently doing forks, thanks for first topic info, will try that route with 17's. Have 5mm preload spacers installed. About fork oil...workshop manual (it exists) calls for 10W oil..the kyb G10, so stock valving, no matter how off it is, is based around tennish. K tech shock stacks are dual stage with a little less turbulent passage entries on valve, but actual holes "seem" the same.
