FITTING

Fig. 1. Spring retainers for Ikon Shock Absorbers

  1. When the coil spring of the original shock absorber - or an IKON coil spring - has to be fitted, the following should be taken into account:
    • Place the bottom spring retainer in the lowest position.
    • Fully extend the shock absorber with the piston rod uppermost.
    • To facilitate the fitting of the upper open spring retainer (e) the bump rubber (d) should be placed approx. 1 cm under the upper eye.
    • Fit the spring (in the case of a progressively wound spring the coils that are closest together should be placed at the bottom).
    • Compress the spring and position the upper open spring retainer (e).
  2. Align the top eye of the damper with the lower attachment.
  3. Fit the shock absorber with its piston rod in upright position and with the adjustment window a directed to that side of the motor cycle that the adjusting disc (c) is most easily accessible (in most cases the outer side). - lift therefore the rubber cover (b).
  4. If the attachment on the bike has a smaller diameter than that of the shock absorber, fit in that case the furnished bushing.
  5. Verify, after fitting of the shock absorber, if the latter with its upper and lower attachment is fully free of any fitted luggage carriers, gear cases etc. If spacers are necessary, fit in that case the furnished spacers.
  6. Tighten the nut or bolt as follows:

ADJUSTMENT

The damping force is adjustable by means of the adjusting disc in the upper eye. As circumstances and/or load may require, you may choose from the following 4 positions (clicks numbered 1-2-3-4):

    1. For very smooth damping under modest loading.
    2. For solo and pillion passenger use on average to good roads.
    3. For sporting solo riding or for use with pillion passenger and luggage.
    4. Heavier adjustment than strictly necessary for use with pillion passenger and luggage.

ATTENTION

The left and right handed damper should always be adjusted to the same position, thus showing the same number on the adjusting disc. The adjustment disc must be snapped exactly into its adjustment position, and not left between positions. The MIN. position 1 and MAX. position 4 have a perceptible stop.

In addition to the above mentioned adjustment of the damping force the preload of the spring can also be changed by means of the lower spring retainer. With the hook spanner supplied there are 3 adjustment positions possible:

  • lower position for solo use.
  • centre position for pillion passenger use.
  • top position for heavy pillion passenger use.

The spring retainers of both dampers should be always adjusted to the same position.
