Product Description
Ensure the internal power transfer of your engine remains smooth and reliable with the Genuine Royal Enfield Front Duplex Chain. This critical primary drive component (Part No: 113007) is located inside the left-hand crankcase (primary cover) and connects the engine’s crankshaft sprocket to the clutch drum.
As a duplex (double-row) chain with a 90-link configuration, it is engineered to handle the high torque output of Royal Enfield’s 350cc and 500cc engines. Unlike standard single-row chains, this heavy-duty duplex design provides a larger surface area for load distribution, significantly reducing wear on the sprockets and ensuring a longer service life. Replacing a stretched or worn primary chain is vital for eliminating “primary slap” noise and preventing damage to the clutch assembly and engine casings.
