The first time I saw an advertisement for Ikons the mentioned that they were based on Koni. I know Konis well. Shop I worked at sold, Honda, CZ and Maico. We did a bit of custom work at the time. Extending travel on the dirt bikes. In some cases we laid the shocks down or moved the shock forward on the swingarm. Back then we were shooting for 7-8 inches of travel. We used pretty much all Koni. We rebuilt the shocks and tuned the compression damping valve. Gas shocks took over shortly after. Yamaha got their Monoshock.
I meet the Ikon guys about 4-6 years ago at an expo. They confirmed they were the old design. I was thinking about using a set on another bike but you had to order from Oz and with shipping there were other good shocks I could get faster and for a similar or slightly higher price. If I had issues, the guys were local (sort of). I like the the koni cuz it are pretty easy to rebuild. Also the technology matches the age of the bike.
It's good to know they are more set up in the US and hopefully the distributor is stocking.
