Product Description
The KIT D09 is manufactured by Rolon (L.G. Balakrishnan & Bros Ltd) to the original dimensional standards of the classic Royal Enfield “Heavy Crank” era. Unlike the newer O-ring kits used on UCE models, this kit features a high-tensile Solid Bush Roller Chain designed to fit the specific sprocket spacing and chain case dimensions of the older cast iron engines.
The rear sprocket in this kit features the traditional 6-hole mounting pattern (bore type) found on the older drum-brake hubs. Both sprockets are induction-hardened to withstand the “thump” of the long-stroke engine, ensuring the teeth do not “hook” or chip under heavy acceleration. The chain is pre-stretched at the factory to minimize the need for frequent adjustments during the initial run-in period.
Key Features:
-
Vintage Fitment: Engineered specifically for the 38-tooth rear hub used in 4-speed gearbox configurations.
-
Solid Bush Technology: Provides high fatigue strength and prevents pin wear, which is critical for engines with heavy power pulses.
-
Induction Hardened Teeth: Carbon steel sprockets with heat-treated teeth for maximum wear resistance against road grime and dust.
-
Corrosion Protection: Zinc-coated rear sprocket to prevent rusting and surface degradation in humid conditions.
-
OEM Standards: Matches the factory specifications of the original Royal Enfield Part No. 112146.
