As I wrote, I changed the pre-load on rear shock to 9 clicks from top. Hard to say, maybe small change to better. Day after I've found out that I have 2,6 bar pressure in tires. I've put there 2,9 bar following manual. Kicks to my back are much much stronger and also front is harder. In thread "OPTIMAL TIRE PRESSURE" people discussed also about suspension. I don't know, what to do. I think, that Triumph and Avon engineers have much much more experiences and knowledge, but surely also have different riding style, weight and figure.
So there are 3 options:
1, play with suspension
2, play with tire pressure
3, leave it on factory settings.
I think, the tire pressure should be as requested by producers, they know why. Maybe little less, but there is a question, how much is little and how much it helps. Suspension setup is a bit complicated, I don't understand it completely and have no experience. Factory settings are not comfortable but sometimes is better to adapt than to change.
