In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed.

Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity (angular, or otherwise) of the system. More precisely, a flywheel's stored energy will donate a surge in power output upon a drop in power input and will conversely absorb any excess power input (system-generated power) in the form of rotational energy. Smoothing the power output of an energy source.

When you’re on the throttle this translates to the power building up and coming on more smoothly, giving you increased traction and less stalling at low RPMs. A heavier flywheel can make a big difference to the characteristics of your dirt bike’s engine.

Delivering energy at rates beyond the ability of an energy source.įor example, flywheels are used in reciprocating engines because the active torque from the individual pistons is intermittent. For HUSQVARNA TE 250i (Fuel Injected) 2018-2022.

This is achieved by collecting energy in a flywheel over time and then releasing it quickly, at rates that exceed the abilities of the energy source.

Controlling the orientation of a mechanical system, gyroscope and reaction wheelįlywheels are typically made of steel and rotate on conventional bearings these are generally limited to a maximum revolution rate of a few thousand RPM.

High energy density flywheels can be made of carbon fiber composites and employ magnetic bearings, enabling them to revolve at speeds up to 60,000 RPM (1 kHz). Ī flywheel may also be used to supply intermittent pulses of energy at power levels that exceed the abilities of its energy source. This is achieved by accumulating energy in the flywheel over a period of time, at a rate that is compatible with the energy source, and then releasing energy at a much higher rate over a relatively short time when it is needed.

CRF450L / CRF450RL Performance Modification Guide.

Trail and enduro riders will love the extra flywheel weight.

Smoother, more controlled and tractable power delivery.

Additional items you will need to have: Common mechanics hand tools, flywheel puller (Steahly part number E-73 or similar), a metal hammer, a torque wrench, and some metal cleaner such as contact cleaner. A special tool is included which will help you press the weight ring onto the rotor without the use of a hydraulic press. Seller 99.1 positive Seller 99.1 positive Seller 99.1 positive. The weight ring is permanently attached to the rotor by means of an interference (press) fit. You must remove the rotor (stock flywheel) from the engine using a proper flywheel puller. Installation Procedure Summary: Installation can be done by someone with average mechanical abilities.

What's Included: Kit includes weight ring, installation tool, replacement cam chain guide bolt and bushing, and detailed instructions. Home > Dual Sport > Honda CRF450L/RL > Steahly Flywheel WeightĪdd 7 ounces of flywheel weight to your CRF450L/RL/X to help reduce stalling, make the power easier to control, and make it more chugable in technical riding sections.
