Yeah, 5.4 kg. I'm not quite sure how accurate that number is, it's the Yamaha part rated at 5.4 straight-rate. I will take the whole shebang (shock and forks) to a tuner next month when my vacation is over(too busy riding everyday right now) and let him check the rates.
I feel underdamped and undersprung. I will post sag numbers tomorrow when I get to measure them, but they are something like 10 mm free sag 100 mm race sag(=standing on pegs, support from wall). I can't concentrate on the other damping circuits when normal landings(video tomorrow, this was about 4-5 feet in the air, landed on slight downslope) hurt my wrists and the frame drags on the ground.
BTW, I totally bottomed my dads KTM 380 on the same landing with compression damping set to full hard, so maybe I somehow disturb the laws of physics while riding.
