Atlantic 125/250/500 Sprint
TYRES
This vehicle is equipped with tubeless
tyres.
WARNING
Periodically check the tyre inflation
pressure at room temperature, see page
75 (TECHNICAL DATA).
Measuring pressure on hot tyres will
lead to inaccurate measurement.
It is especially important to measure
tyre pressure before and after a long
trip.
Over-inflated tyres will not absorb
bumps when riding on rough road
surfaces and resulting vibration is
transferred through the handlebar,
giving a harsh ride and reducing tyre
grip especially during cornering.
Conversely, under-inflation will put more
stress on the sidewalls (1) and the tyre
may slip on the rim or even come off the
rim, leading to loss of control.
The tyres could come off the rims under
harsh braking.
Finally, the vehicle could skid during
cornering.
Inspect tyre surface condition and check
for wear, as worn tyres lead to poor road
holding and handling.

indicators.
For more information on how to check
the tyres for wear, contact your Dealer.
Visually inspect the tyres for wear and
have them changed if worn.
Old tyres, even if not completely worn
down, may become hard and provide
poor grip.
If so, have them replaced.
Have a tyre changed when worn or
punctured, if the puncture in the tread is
larger than 5 mm.
Have the wheels balanced after each tyre
repair.
Use only tyres in the size suggested by
aprilia
, see page 75 (TECHNICAL
DATA).
Do not install tube tyres on tubeless tyre
rims or vice versa.
Always check that the caps are in place
on the valves, or the tyres may deflate
suddenly.
Tyre replacement and repair, as well as
wheel servicing and balancing are delicate
operations. They should be carried out
using adequate tools and are best left to
experienced mechanics. Have your tyres
and wheels serviced at an
a p r i l i a
Authorised dealer or a specialised tyre
repairer. New tyres may be coated with an
oily film: ride carefully until covering
several kilometres. Do not oil the tyres
with unsuitable fluids.
