TUNING 171 Suspension Tuning According the Type of Course Lower the front end slightly (Increase the amount of fork tube protrusion above the steering stem head by 5 mm (0.20 in.).). This accelerates steering and enhances turning ability. Raise the front end slightly (Decrease the amount of fork tube protrusion above the steering stem head by 5 mm (0.20 in.).). This slows down steering and enhances stability at high speed. Raise the front end slightly to gain stability. Front and Rear Suspension Compatibility Inspection Many Corners • • • Fast Course Use this procedure to determine if the suspension is balanced reasonably well. Hold the motorcycle upright (remove the side stand.). While standing next to the machine, lightly pull the brake lever, place one foot on the footpeg closest to you, and push down hard. If the motorcycle stays level as the suspension is compressed, the spring rates are well balanced. Sit astride the motorcycle, take a riding posture and check that the machine is in a horizontal position. If one end drops noticeably more than the other, the front and rear are not compatible and must be readjusted to achieve a better balance. Deep Dips or Sandy Ground • • • Begin the actual on-track testing and evaluation after making these preliminary adjustments. Bear in mind the following points when readjusting the suspension. Always make changes in small steps. The rider must be consistent in evaluating suspension performance. A change in the front suspension might require one in the rear suspension, and vise versa. Although this is one of the most effective adjustment procedures, suspension settings may vary
