Pretty hard to give suspension tips for we do not know the weight of the rider(s), height, how they ride, where they will be riding & how they take the bends of more so if they are on for Track Days or actual competition where a true suspension man is needed.
Most do now know that Compression, Pre=Load, or Rebound it or even where it is on their bike front or back to some Suzy bikes do not have it on the front. Besides often a rear shock will have to replace the stock one, to special work to be done by a firm accustom to rebuilding stock forks.
The above may sound usless & it is if someone errors part way along. My suggestion is to keep you eyes on some of the m/c mags when they start to have an article or two on the above matter. RoadRacing World is a prize one for some of the best tuning methods applied to long distant races & even more.
Obviously the reason a good road racer has a tuner is because he runs thing in general along with the assistance of a suspension specialist so the type of course, the weather conditons & such drop into the hands of the suspension man along with the engine tuner.
Remember all the others on the road are crazy & out to kill you.
