[QUOTE="Tom Gaynor, post: 21565, member: 4034"] John Emanuel has a Rapide with the suspension seriously modified. He altered the pivot points on the Girdraulics so that they worked the way they are claimed to work (no change in wheelbase with deflection), but don't. He told me that the key to improving the rear suspension was to allow the wheel to move through the maximum arc, which meant getting rid of the claws, and allowing (presumably) the damper to act as stop. This gave about 3" more travel. (The conversation was a while back, so this is what I remember. He must also have converted to Series D, which is probably a good idea anyway.) What I remember particularly well was someone who went past me at Braddan Bridge in IoM in 2007, going like a rocket, perfectly stable until he went rapidly out of sight. This, it transpired, was John. He was first back after the lap. The memory that remains was of both speed AND stability, quite evidently in a different class from anything else that came past. I tell a lie: Patrick Godet sailed past on his Prince coming down the mountain. It was like being overtaken at 90 mph by a square-rigged ship under full sail. As to your direct question, it won't help you to recount that mine went on nae bother, with Petteford springs. I have Thornton dampers fore and aft. [/QUOTE]
