Suzuki GR650 Tempter
From Suzuki Wiki
The GR650 was a standard Motorcycle built by Suzuki.
The GR650 featured an air-cooled DOHC Parallel twin engine with chain drive and was designed for nimble handling. It featured a two-stage flywheel which used a centrifugal clutch to lower flywheel mass above 3,000 RPM.[1] This was intended to provide easier take-off at low RPM and better reponsiveness at higher RPMs. It also featured a progressive mono-shock rear suspension.
To induce better swirling of the air-fuel mixture in the GR650 engine, Suzuki used a "sub-intake port," which ran a tube from the carburetor throat to the intake port just above the valve head. Suzuki claimed that this allows the GR650 to run with a leaner mixture than usual, which improves economy.[2]
