It has two jobs. It smooths the power delivery of a single cylinder engine, which fires only once every two revolutions and would otherwise deliver drive in pulses, and it provides the mounting and pivot points that let the shoes fly outward under centrifugal force to engage the clutch bell.\u003c\/p\u003e\u003cp\u003eThe lightweight designation changes how the engine behaves rather than just saving grams. Less rotating mass means the engine revs up and down more freely, which gives sharper throttle response and lets it recover faster after a corner. The trade-off is that a lighter flywheel stores less energy, so the engine is slightly more prone to bogging at very low rpm.\u003c\/p\u003e\u003cp\u003eNote that the 3PC in Kyosho's naming refers to the three-shoe clutch type this flywheel is built for, not a pack quantity. Kyosho lists it as an option part for the DRX.\u003c\/p\u003e","brand":"PowerHobby","offers":[{"title":"Default Title","offer_id":44532864680024,"sku":"KYOTRW159","price":27.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0554\/8376\/files\/trw159_abc2491a-3254-42e1-85ec-c799c04fd538.jpg?v=1786243019","url":"https:\/\/beavertonmilestonehobby.com\/products\/kyosho-trw159-3-shoe-lightweight-flywheel-drx","provider":"Beaverton Milestone Hobby","version":"1.0","type":"link"}
