MCS Coils

49 products — part of all Coils

MCS ignition coils serve Harley-Davidson motorcycles across a remarkably wide historical span, from the 1930s Big Twins and 45-inch Flathead models through to the classic points-style ignition setups still favoured in custom applications today. While modern Harley-Davidson platforms have moved to electronic engine management, a substantial portion of the bikes on UK roads still run points or traditional ignition systems that depend on a reliable, correctly specified coil to fire consistently. MCS provides straightforward, well-priced replacement coils for these applications — covering 30-47 Big Twin and Flathead machines, 48-69 Big Twin motors both in 6-volt and converted 12-volt electrical systems, and universal points-style coils suited to custom bobbers and period-correct restorations. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, holds MCS coils in stock to support riders working on vintage and custom projects that fall outside the scope of what OEM suppliers still cover. For anyone rebuilding a Panhead, Flathead, or running a custom ignition setup on a stripped-back machine, the MCS coil range offers reliable, accessible solutions without the premium pricing of specialist vintage parts houses.
