The chain on your Royal Enfield motorbike plays one of the most important parts of riding it. Essentially it is the chain that gets the motorbike moving. Every 400 km or so and when you feel the chain needs some lube, do put the motorcycle on its main stand or paddock stand and clean the chain by rotating the tyre with your hand. You might as well use a designated chain cleaning liquid and brush and let it stay for a while. Then run water through it till the water that’s flowing out becomes clean. Once the chain is clean, use a good chain lube spray on it. Make sure you’ve reached all the chain links.
