| Andy b - not sure of your experience so I may be teaching granny to suck eggs etc....but Take care with advice from others. Make sure you set the bike up the way it suits you - Not John Hacket or the way neil Hodge has his set-up.
I fitted a heavier spring on Johns recomendation....less preload tension on a heavier spring is supposed to giving a more progressive ride response and better adjustability.
I hated the choppy ride, I spent months trying diferent adjustments with preload, rebound and compression. Eventually I went back to the standard spring.
Its a bit like the front steering head angle - some people will say ohh no leave it alone - nobody races with the steeper head adjustment. I love it, quicker turning without the rear of the bike high in the air gives me the confidence I need to get the power down early without the fear of highsiding.
We all ride a bit differenly. |
