I ran the 420 gram weight on my race trike & loved it! It allowed the motor to lug around the tight corners without stalling & a quick stab of the throttle allowed the motor to still accelerate faster than stock. If your not planning on riding at slower speeds for any reason then don't bother with the weight is my opinion. For a duner or drag motor I would stick with the stock CR set up.
The picture on the Left shows the 2001 vs 2007 Flywheel. Second and third picture shows the 2001 and 2007 balanced. Note the 2002 to 2007 Flywheels look the same externally, and work for all years from 2002 to 2007, however they are different internally. Our custom Flywheel weights are specific to each year IGN from 2001 to 2007, and specific to the engine CC size, application and level of rider.
As an example, an OEM Ported cylinder vs a 370CC Sphynx vs a Puma vs a Saber all utilize different weighted flywheels for optimun performance and reliability.
Our weighted flywheels are also coated with a conductive coating to promote magnetic field stabilization and prevent rust.
i found that with the 125 cdi box i have no stall issues
