Shinning light on the Rear Shock
So recently I was at the track with this disaster of bike. Everything seems to be solved and I can move onto the handling characteristics of the 749.
One of the suspension experts at the track started talking to me about my rear shock being too soft for my wieght. That said, his immediate response was to either changet he spring or upgrade me to something that has a "top out" spring in it or do both change the spring and get a shock that has a "topping out spring" on it.
Now, I have some quetions... it is my understanding that having a shock with a top-out spring in it will HELP prevent the rear wheel from loosing some grip when the brakes are applied. However which shocks will provide such a feature? Presently, I have the so-called crappy Sach shock on my bike.
In terms of Sag this is what the bike is set up with:
-Front Forks (0.9kg springs Showa TIN) 35mm of rider sag and 30mm bike sag
-Rear shock with stock spring (don't know the wieght) was at 42mm sag in the rear which caused the bike to UNDERSTEER incredible and has been changed to 28mm sag. Note that the stock spring length is something like 164mm and mine is measuring 151 while the bike is sitting upright (on a rear stand) so i don't think that I Have OVER-PRELOAD the rear shock enough to warrent a new shock assembly in the rear.
My Scuderia : 2006 Ducati 749d - Showa TiN forks, Bitubo Steering Dampener, Ohlins rear shock (ARNOLD HASTINGS!!! AMA 2008 ), Dunlop 209/208 tires
