COMPOSITE MATERIALS

The company Blata is the rst among minibike manufacturers to bring modern com-

posite materials. The Minibike Ultima uses carbon not only as a fashion supplement,

but as a fully functional material, which exceeds the characteristics of classic metal

materials. Composite materials bring not only an uncompromising lowering of weight,

but also radical rigidity and excellent damping characteristics. You will immediately

recognize the positive difference in the riding characteristics during the rst ride on

a minibike which is tted with such components. The carbon front fork, the supports

for the under-seat frame and the supports for the rear forks are manufactured using

the unique patented technology of axial ber winding.

The Minibike Ultima is also t-

ted with other composite com-

ponents. The cap for the starting

and the foot pegs are made from ther-

moplastic polyamide, which is reinforced

by ultra long glass bers.

NOISE

DECLARATION ABOUT NOISE

The operational conditions during measuring are contained in the Report about noise

measuring which is stored at the manufacturer.

Measuring is performed according to the regulation: UEM RR011 (version 2009)

The prescribed noise limit according to UEM RR011 is 95 dB (A) in the range of the mo-

tor’s revolutions of (8000 to 9000 min

-1

). The prescribed noise limit was not exceeded.

The stated values are emission levels and may not resemble safe working levels.

Even though there does exist a correlation between the emission levels and exposure

levels, these values cannot be used to reliably determine whether further measures

are necessary or not. The factors which affect the actual levels of exposure to workers

include the characteristics of the working area, other sources of noise etc., for exam-

ple the number of machines and other neighboring processes. The highest allowable

level of exposure can also be different in individual countries. This information is to

serve the user of the machine to better evaluate the danger and risk.
