INSTRUMENT AND CONTROL FUNCTIONS4-194The spring preload setting is deter-mined by measuring distance A,shown in the illustration. The shorterdistance A is, the higher the spring pre-load; the longer distance A is, the lowerthe spring preload.Rebound damping forceThe rebound damping force is adjust-ed on the right front fork leg only.To increase the rebound dampingforce and thereby harden the rebounddamping, turn the adjusting screw indirection (a). To decrease the rebounddamping force and thereby soften therebound damping, turn the adjustingscrew in direction (b).TIPAlthough the total number of turns of adamping force adjusting mechanismmay not exactly match the abovespecifications due to small differencesin production, the actual number ofturns always represents the entire ad-justing range. To obtain a precise ad-justment, it would be advisable tocheck the number of turns of eachdamping force adjusting mechanismand to modify the specifications asnecessary.1.
