TIRES & TUBES
Tyres are an essential safety factor on your Mini-Motorbike. They must be properly inflated and free from
excessive treadwear to maintain adequate traction levels and ensure longevity.
Tyre pressure measurement
Maintaining proper inflation is the single most important thing that you must do to ensure tire durability
and maximum tread life. With the proper tire pressure, your tires will be far less prone to damage from
sharp rocks and other obstacles that may be encountered when off roading. It is imperative that your Mini-
Motorbikes's tire pressure is measured when the tires are "cold." Failure to do so will result in an inaccurate
pressure reading.
Recommended Tire Pressure
Front: 2 Bar (KG)/29 psi
Rear: 2.2 Bar (KG)/32 psi
Further, make sure to always check the depth of the tyre tread. Have the tyre replaced when the tread depth
at the center is less than 5 mm (0.2 inches) or when you notice reduced tyre traction. Another important
component to check is the valve stem. Any tilt in the valve stem tells that the tube is not centered over the
hole. In such situations, please contact your nearest authorised YCF Mini-Motorbike dealer, as this can cause
puncturing of the tyre with subsequent accident.
Before riding, always check the wear of the tires and verify the absence of crevices and fissures, protruding
nails and glass splinters, as well as rocks or other embedded foreign bodies. Remove these particles before
riding.
Warning
Maintaining correct tire inflation pressure is paramount to optimise your safety as well as your Mini-
Motorbike's performance. Never ride your Mini-Motorbike if the tyres are insufficiently inflated, over-
inflated or worn out. Failure to overlook these warnings may lead to the deflation of the tyres and loss of
control of your Mini-Motorbike, with subsequent serious injury or even death.
