JT Sprockets Sprockets & Chains

43 produits

JT Sprockets handles the unglamorous side of Harley-Davidson drivetrain work — the sprockets and chains that quietly transfer power from the gearbox to the rear wheel until they suddenly don't. The company turns out millions of sprockets a year using case-hardened chromoly steel, which is the metallurgy that lets a sprocket survive a winter of salty roads and still shift cleanly when the chain finally needs replacing. JT supplies front and rear sprockets cut to OEM tooth profiles for the older chain-final Sportster XL platforms, chain-conversion custom builds, and the Harley-Davidson workshop jobs where a sprocket swap is part of a scheduled service rather than a styling decision. Their range is built around choice — multiple tooth counts, multiple pitches — so owners experimenting with gearing for touring loads or city work can find the ratio that fits. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks the JT range for chain-driven and conversion applications. Browse the full JT Sprockets Sprockets & Chains range below.
