MCS Transmission Gears

7 products — part of all Transmission Gears

MCS transmission gears for Harley-Davidson are precision-machined components that transfer power through your gearbox with the smoothness and reliability that daily riding demands. A worn transmission gear — whether the result of high mileage, missed gear changes or a seized bearing — introduces gear noise, false neutrals and eventually complete gearbox failure. MCS stocks individual and paired transmission gears across the Harley-Davidson four-speed, five-speed and six-speed gearbox families, allowing a targeted repair of the affected ratio rather than a wholesale gearbox replacement. Each gear is sourced to OEM tooth profile and hardness specifications to ensure correct mesh with adjacent components. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks MCS transmission gears as part of a comprehensive gearbox rebuild programme.
