Burgman 650 de Suzuki

This section introduces some of the methods utilized in reducing noise in the large “Sky Wave 650” AN650 scooter.

A Utilization of an Electronically Controlled CVT*
This is the first ever utilization of an electronically controlled
CVT in a motorcycle. It allows reduced engine rpm and operating
noise, while improving on fuel economy under normal driving
conditions.

* CVT: Continuously Variable Transmission
B Utilization of Helical Gears and Sound Absorbent Cover
A helical gear system utilized in the transmission reduces operating
noise when driving.
To reduce noise, the gear case cover incorporates sound absorbent
materials to block transmitted sound and resonance sound
of the cse.

C Utilization of Sound Absorbent Body Covers
Sound absorbent materials are incorporated in covers on both
sides of and underneath the engine to reduce noise emissions.

Exhaust Emissions

The Sky Wave 650 incorporates a fuel injection system, honeycomb
catalysts, and second stage air system. Technologies accumulated
through years of development have been applied in areas
such as engine layout and optimizing control systems in order to reduce
exhaust emissions. (Meets 1999 Exhaust Emission Regulations)
