219 Primary Silent Chain Drive Conversion Kit

REV797 219 Silent Primary Sprocket Kit – for Light Bee, 79Bike Falcon, Rerode R1/R1+, Ventus one/one+ & E-Ride Pro S

Machined from heat-treated tool steel, this 219 primary sprocket kit is built for riders who notice sound and feel. At low speeds it runs almost silent, then under throttle it delivers a crisp, two-stroke-like “raaaaaraaaaaa” instead of chain slap and drivetrain chatter.

The sprockets are thickened only where the chain actually loads, reducing deformation while keeping mass controlled. Matched front and rear sizes spread the load evenly, easing chain tension, smoothing acceleration, and extending the life of both chain and drivetrain.
