| My first wedge would go on getting the suspension set up for you personally, whether it be the standard set up or thats not good enough, or you are very light/heavier than average getting it resprung and valved.
Starting point would be get ride height, sag then damping settings sorted, although by the sounds of it you're pretty happy anyway.
Good matched tyres as well, and a riding course.
Then after that it becomes a case of how deep is your wallet when you go for, how much bling you want etc. |
