Ah IKON brings back memories just to look at them and know that the same exact part design has been doing that function for d@mn near 50 years!
As you may know if you already bought a pair, IKON took over the KONI Dutch suspension company's old tech motorcycle division's tooling, shipped it all to Australia and have been making identical products for at least 20 years. There have been some comments on the forum that some of the welding quality has dropped off when or since R3 ones were released. Who knows if they have re-tooled since the original Koni stuff?
A very solid basic design known for quality and was the BMW airhead boxer standard for many years. The model codes are still the same too with the 7610 series twin shock still in use.
