At DMG Motorsports, we present the Vortex Rear Sprocket Aluminum 42T-525 Silver for Honda (part number 252-42) — a race-proven drivetrain upgrade built for riders who demand less rotating mass and more durability. Vortex has long been regarded as an industry benchmark, and this sprocket carries that reputation onto your Honda's rear wheel with a design trusted across the paddock, from weekend track days to championship-winning race teams.

Machined from premium 7075 aluminum, this 525-pitch, 42-tooth sprocket sheds unnecessary weight compared to steel OEM units, helping reduce rotating mass for snappier acceleration and improved handling. Its patented tooth profile is engineered to work seamlessly with your chain for smoother, more consistent power transfer, while the silver anodized finish adds a clean, race-ready look that holds up to hard use.
