Hello, you have to be realistic...
The original suspensions of the Rocket are of good quality for a guy who rides quietly without really asking questions !!!
For the others, those who want to send big gas or those whose weight exceeds 100 kg, they are quickly exceeded. I have another bike mounted with Öhlins and I can tell you that the slightest change in setting is noticeable which is far from being the case on the Rocket.
So, for those who are fanatics of well-tuned motorcycles, there is only one solution: put Andreani cartridges in the forks and an EMC at the rear... You will finally have suspensions adapted to your weight, to your feelings and adjustable in all directions!
NB: I don't get any discounts from these manufacturers (unfortunately...), they are simply the only ones I have found that offer these products...
