Renthal – Renthal Sprockets, including front grooved and Ultralight sprockets, rear grooved sprockets, Twinring sprockets, hard anodised street sprockets and sprocket hardware and kits, gearing is the simplest real performance change on any chain-driven machine, and this range covers both ends of the drivetrain. Front sprockets are grouped by brand, pitch and machine type, spanning Honda CR, CRF, XR and street models, Kawasaki 420 and 520 pitch fitments, KTM, Husqvarna and GasGas, Suzuki and Yamaha dirt, ATV, mini and street applications, with grooved and Ultralight options in 12 to 16 tooth counts. Rear sprockets run from 40 through 54 teeth in grooved aluminium, hard anodised and the two-piece Twinring design that combines an aluminium inner carrier with a steel outer ring for a long service life without the weight of full steel. Coverage includes 415, 420, 428, 520 and 525 pitch across Honda, Kawasaki, KTM, Husqvarna, GasGas, Suzuki and Yamaha, plus Honda CBR, BMW S1000RR and carbon-wheel PCD fitments. Sprocket hardware and kits finish the job. Changing one or two teeth sharpens acceleration or lowers rpm at cruise, so you can tailor drive to the track, trail or road you ride.
