At DMG Motorsports, we present the Vortex Aluminum Rear Sprocket 43T-525 in Silver (454-43) — a race-proven upgrade built for Kawasaki sportbike owners who demand precision, durability, and reduced rotating mass. Vortex has earned its reputation as the standard in the race industry, and this 525-pitch, 43-tooth rear sprocket is engineered to deliver the same performance trusted by champions on the track and street alike.

Machined from premium 7075 aluminum, this sprocket combines exceptional strength with a significant weight savings over stock steel sprockets, helping to reduce unsprung rotating mass for quicker acceleration and sharper handling. Its unique tooth design is engineered to extend sprocket life while maintaining smooth, consistent chain engagement, and the silver anodized finish provides protection against corrosion while giving your bike a clean, race-inspired look.

Whether you're replacing a worn OEM sprocket or building out a full drivetrain for track days, the Vortex 454-43 delivers the fit, finish, and performance that serious riders expect. Pair it with a matching Vortex front sprocket and chain for a complete, race-tested drivetrain upgrade.
