Front Suspension Inspection
With a well functioning front and rear suspension you are able to ride your Mini-Motorbike safely and with
stability. When visual inspection indicates that some suspension parts may be worn or damaged, contact
your nearest YCF dealer to check your Mini-Motorbike for
replacement parts if necessary.
Front Suspension Adjustments
1. To check the fork, pull the front brake lever in and hold
it there. Press downwards on the handlebar and let it go
upwards. The whole set of movements should be very
smooth and show a swift rebound.
2. When visual inspection indicates that some bolts or nuts
may be rusted or damaged, contact your nearest YCF
dealer to check your Mini-Motorbike for replacement
parts if necessary.
For model SP3-F150, SP3-F190, BIGY 190 MX, equipped with
"ENGI" fork, there are 2 possible regulations, at the top, the
relaxation or "the bounce"(recovery") and below the regulation in
compression. For these 2 regulations, it is enough to squeeze(tighten) the screws of the tube of fork clockwise those from
above ( A ) to harden the relaxation and those from below ( B ) to harden the compression.
