[QUOTE="greg brillus, post: 51958, member: 597"] Thanks for the photos David, As some of you will know from the thread that was discussed in huge detail re the Comet suspension, this is a take on the subject, and now awaits testing. The whole concept is based on the bad handling characteristics of Girdraulics, backed by the fact that so many owners have suffered some bad and some really bad experiences. The main problem as discussed with Girdraulics is the spring set up in standard form is way too stiff, especially if you are a fairly light rider such as myself, and secondly, the position of the links by comparison to Bramptons is not good. Although there are many of you who are still to some extent very wary of Girdraulics, there are improvements that can be made, and some quite inexpensively, that can reduce the problem. The modifications I have done to the links are to reduce the high level of friction that exists, particularly in the eccentric bushes. The new steering stem has been redesigned to position the rear of the lower link down and aft. This will put the lower link in a similar position to that of the Bramptons lower link without the need to drill extra holes in the fork blades......A mod that most Vincent owners would likely frown upon.
