My pick for new shocks on a stock Vincent........Either an Ikon or new Maughans one on the rear, the Ikon is quite stiff in action but works fine. On the front a new Maughans one is perfect.......they are soft in action like an original but dont leak. The Avo's work fine although they dont look original, i found them to be ok on a twin but way too stiff for a Single. The new Ikon is too stiff for the front of either a twin or single.......Original Koni's work well on the rear and one that is reasonably soft will be fine on the front.......If you wish to soften the ride of your bike, the first thing to do is check the springs front and rear.......many bikes still have the duel springs per side at the front........way over sprung.......on the rear many bikes have sidecar springs in the cases........rear springs that have a wire diameter of about 0.325" are sidecar ones and way too stiff........solo springs should be around 0.300" wire.........these 2 items are very common on these bikes........Cheers.
