• The data shown above are those in the case of one straight pipe.

• Specifications are subject to change without notice.

• This spark ignition system complies with the Canadian standard ICES-002.

Note 1: Noise emissions in the environment measured as sound power (L

WA

) in conformity with EC directive 2000/14/EC. Reported 

sound power level for the machine has been measured with the original attachment that gives the highest level. The difference 
between guaranteed and measured sound power is that the guaranteed sound power also includes dispersion in the measurement 
result and the variations between different machines of the same model according to Directive 2000/14/EC.
Note 2: The equivalent sound pressure level value is calculated with a work cycle of a duration of 1/7 for idling and 6/7 for racing. 
Reported data for equivalent sound pressure level for the machine has a typical statistical dispersion (standard deviation) of 1 dB(A).
Note 3: The equivalent Vibration total value is calculated with a work cycle of a duration of 1/7 for idling and 6/7 for racing. Reported 
data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 1 m/s
