A coil over on the front end is definitely the best option to free up the girdraulic forks........there are several issues that make it somewhat difficult........ Limited space is the biggest hurdle.......trying to keep the shocker body and the spring away from the rear of the upper link is the big one.......but also the minimal travel available. The lugs on the FF1 are probably on the limit if used on a twin with all the features and extra weight of a road bike with all its equipment.......Some of us have done it on racers and on mine, with the JE modified stem, plus the modern coilover in place of the stock shock absorber, needle rollers in place of all the FF6 bushes and Titanium spindles to finish it all off.......From my experience on these bikes thus far, it was easily the best Vincent front end ever.........Of course all these things can be done to a lesser extent with I feel still excellent results, the common problem is making batches of parts that anyone might want and to what cost........A short while ago I had Ikon here in Australia make me a batch of 10 special re- valved shocks to my specs that were "Special order" that they would not make and sell to anyone else.........Probably a bit like the ones made for Laney Thornton.......Anyway these are all gone now.......They were set up far, far softer than the stock Ikon ones........I explained to their engineer that a Vincent simply does not need a stiff heavy action front shock absorber........if there is any doubt ......Look at the damping on a set of Bramptons......the unsprung weight is basically the same.......The inbuilt friction of the spindles/bushes takes care of that......... I have just received a Shadow in my shop from a new customer who had only ridden the bike once since he bought it about 3 years ago....... I physically could not push the front end up/down on the bars........even when rolling the bike forward the front end was near seized.......This turned out to be no more than the remnants of some old hard grease and grit on the sliding walls of the front spring cases.......once removed and washed clean, the tubes telescoped beautifully again.......friction counts for everything on these front ends.
