Royal Enfield has introduced official E20 conversion kits for its older motorcycle lineup to ensure compatibility with 20 percent ethanol-blended fuel. While the brand’s BS6-compliant portfolio has been E20-ready since 2020, these new kits specifically target older carburetted models that may face long-term reliability issues with higher ethanol concentrations.
The E20 retrofit kits are primarily designed for BS3 and BS4 Unit Construction Engine (UCE) models. This includes popular variants such as:
While the kits are focused on 350cc engines, owners of 500cc UCE motorcycles are also advised to upgrade specific fuel system components to prevent potential blockages caused by ethanol’s corrosive properties.
Increased ethanol content in fuel can accelerate the wear of standard rubber and metal components. To mitigate this, the Royal Enfield E20 kit includes replacement parts that are more resistant over the long term. These include:
The manufacturer’s recommended price for the BS4 model kit is Rs 1,701.
These conversion kits are available through authorized Royal Enfield service centers. However, because stock levels vary by location, owners are encouraged to contact their local dealership to confirm availability before visiting.
