I don't know if you ride on the road much Ungarisch,but I'd love to know if the forks can deal with roads without feeling harsh and uncompliant.
After I installed it, I did take it on a 5 miles ride on the road to have all of the oil settle back down to the fork bottom and regian damping ability. Better do that at low speeds on the streets than go hit the track and realize the first corner you got zero damping, lol. The best that I can describe my short ride on the street was that it was plush while at the same time also very supportive. We have terrible roads here in Los Angeles, not potholes ridden but just shitty concrete slabs segments instead of smooth asphalt, which is very jarring to ride on as you feel all the gaps where they join. I was surprised how well it floated over them.
To be honest, I've run both the standard 3rd gen Showa 41mm USD forks (both stock and full RaceTech GoldValve build) and the 4th gen Showa SFF-BP forks. On the street, the BP forks were miles more comfortable than the original 3rd gen forks. Going from the 3rd gen forks to the K-Tech's would have been a massive difference in regards to comfort, while going from the 4th gen BP forks to the K-Techs, there definitely is a difference in comfort but not astronomical. The bigger difference is support and accurate damping ability. The BP's were very "dive-y", and mid corner was a bit "pogo-y", and even if you added a bit of rebound and compression they then felt stiff and if they weren't damping the road undulation properly. The K-Tech completely fixes that, the dive is gone, and mid corner at high lean you cannot feel the suspension working underneath you through the bars, which is exactly what it should be doing. I don't mean there is no feal, it's more like the handlebars are not affected by suspension movement. My confidence in trail braking deep into corners went up a massive amount, hence why my lap times came down by a relatively large margin. I'm not sure how/if that would translate into the street riding, but that was the biggest difference I noticed, and I'm extremely happy with the results.
I too am 170lbs, though without gear, and the 9.5NM spring felt perfect on the street, not harsh at all, very plush, while at the track the stroke indicator ring still had about 18mm of gap from bottoming out. Even after some extreme braking when a slower rider cut over in front of me last second before corner entry with 20mph speed delta between us, and having to go into full panic braking, floating the rear wheel. I was very surprised that the stroke indicator still showed 18mm of fork travel left (13mm actual, as there is probably a 5mm bottoming stop) . I might take a few 1 or 2 more turns of preload out of the forks when I go to tracks with really bad road surface.
