March 1, 200422 yr I'm sure this question has been answered loads of times but what's the current view on which oil to use in the front forks? SAE 30 or Auto Trans Fluid. All suggestions appreciated Paul Mac
March 1, 200422 yr I've always used between 180 - 200cc 10 grade per leg in the Betor forks as fitted to Ossas and Bults. Lower amount to achieve softer action, higher for stiffer. I used 200cc 10 grade in my 74 slimline and they worked very well. In my opinion 30 grade is way to thick for forks and with good quality modern fork oil available these days I don't know why anyone would want to use the Auto trans fluid. Ultimately though it's down to personal preference and experimenting with volume and grade but the above spec. is good starting point.
