T roubleshooting Below are a few examples of how to adjust for the most common road holding pr ob- lems in Road Racing driving. 1. The front wheel “chatters” entering a corner , the problem goes away , as soon as you let the brakes off, or when you get on the power .
Guidelines The settings on this pressurised Fr ont Fork are based on what curr ently is being used in Moto GP racing, furthermore the delivery spec is something we like to refer to as a “balanced setting”. This means that the pressur e drop over the bottom valves (base valves) and the top pistons (ø25mm) are matched.
Individual adjustments Individual adjustments Below you can find the recommended ad- justment range for the top left compression leg adjuster , with differ ent positions on the bottom base valve.
