Talk:Suzuki GR650

This article says that the Tempter had a "dual mass flywheel" to decrease flywheel mass above 3,000RPM. This is not what a dual mass flywheel does at all. Dual mass flywheels are most commonly used on diesel engines to help reduce the transmission of vibrations from the drivetrain and thus give drivers a smoother experience, particularly during gear changes. Flywheel mass is never actually increased or decreased, it's simply that the flywheel is a composite design of two separate masses (which are fixed together into 1 unit) with a rotary spring mechanism between them. The masses do not separate during operation. What the Tempter has is a two-stage flywheel. There is actually 2 separate flywheel weights, one of which is engaged via a centrifugal clutch (similar to the automatic transmission on modern motor scooters like the Yamaha Vino, Honda Metropolitan, etc.). This keeps the full auxiliary weight engaged for easier idle and take-off, but then separates the auxiliary weight once spun above 3,000rpm, leaving only the primary, lighter flywheel engaged. The terms of dual mass flywheel vs. two-stage flywheel might seem unimportant, but in truth they are very different mechanisms. I have edited the article accordingly. (Caleb B.
