Tim, last 600SS I had only had one disc, but as the idea was not to slow down to much it was well suited to road use. In my experience on the race track I have found the standard discs fitted to the bottom of the range Ducati's tend to fade with constant hard use, which is what will happen to a standard single disc setup on the track in race conditions. I believe this problem will solved by fitting a SPS type disc and suitable pads plus aeroquip brake line. Then to get better stopping distances I think the 4 pad calliper will give the initial bit that I like to have and will also be less likely to suffer fade. Added to that the benifits of a single disc setup of less weight some of which is gyroscopic I think it would be a ideal setup. And as some 600SSs only come with lugs on one leg then it should be cheaper than buying a 2nd disc calliper, suitable mastercylinder and a set of forks (£400 for Louigis setup) as opposed to about £130 for SPS disc and 4-pad, then you could sell standard disc to some one doing a twin disc setup |
