I wonder what it is that makes them claim the Luftkappe performs better? More negative volume? I've followed all the "I hate my pike" threads that place blame on the damper and the Push ACS3 threads where Darren posted dyno plots showing the dampers aren't really at fault (the high seal friction is what causes the harshness).
I need to do something about my MY18 Pike....just not sure which solution to try. I'm hoping I choose wisely and pick the best solution on my first attempt.
here is my take for my 2018 lyrik debonair vs a 150 (a1-a2 w/ all updates) pike w/ luftkappe. I realize it isn't apples to apples but its all I got. my friends luftkappe pike I would say still has slightly less breakaway force, very very close but I would have to say the luftkappe is still marginally more willing to move, probably most noticeable when trying to climb a tech section. So that is a positive for the luftkappe. However the luftkappe is noticeable more progressive, my friend is having trouble getting full travel now and to the point that he is lowering air pressure, so I'm not so sure how much mid stroke he is losing since he is now dropping pressure to compensate for the added progressiveness.
now my 2018 lyrik with 2019 debonair upgrade only has one ride but I can say I am pretty dang happy. The breakaway force is slightly less noticeable stationary vs stock (its noticeable I just don't want to overstate it). However riding it is definitely noticeable vs stock and when going into steep sections while on the brake the mid stroke support is very noticeable. All this while not being overly progressive and still used travel.
So my take is if you are very aggressive and can use the travel with 2+ tokens over stock setup then the luftkappe will most likely work very well for you since you'll get great beginning stroke sensitive with the progressiveness you already have. If your not as aggressive like me then the debonair is a great in between.
I'm betting a luftkappe version 2 is in the works with a dome 1/2 as high will be coming for the debonair.
