Specifications
Front Fork (per one unit)
Fork inner tube diameter: 41mm
Air pressure:
Atmospheric pressure (non-adjustable)
Fork oil viscosity: SAE 10W-20
Fork oil capacity:
452 +/-4ml (completely dry)
Fork oil level:
140 +/-2mm below from top of inner tube (fully compressed, without main spring)
Main spring free length:
415mm (service limit: 407mm)
• If necessary, measure the oil levels as follows:
• Slowly compress the front fork fully by pushing up the outer tubes using a jack or other suitable means under the front wheel.
• Wait until the oil level settles
• Insert a tape measure or rod into the inner tube, and measure the distance from the top of the inner tube to the oil.
NOTE
• Fork oil levels may also be measured using an oil syringe.
• The tape measure, rod, or oil syringe pipe should be in the middle of the inner tube, or the correct oil level cannot be measured.
• Set the oil syringe stopper so that its lower side shows the oil level distance specified
• Put the gauge tube into the inner tube and position the stopper across the top end of the inner tube.
NOTE
• The gauge tube is graduated in 1cm division
• The syringe body is graduated in 10ml divisions, excluding the gauge tube which is about 5 ml capacity.
• Pull the handle slowly to draw out the excess oil until no more oil comes up the tube.
• If no oil is drawn out, there is not enough oil in the inner tube. Pour in some more oil, then draw out the excess
Fork Oil Level
(Fully compressed without spring)
140+/-2mm
• If fork oil is above or below the specified level, remove or add oil and recheck the oil level
• Install the main spring so that the smaller diameter end faces downward.
• Change the oil of the other fork leg in the same manner.
• Install the parts removed.
