While the E20 conversion kit is designed for 350cc Royal Enfield bikes, some parts can be used with 500cc motorcycles as well

To ensure that its customers can continue to enjoy a hassle-free ride, Royal Enfield has introduced E20 conversion kits for its old BS3 and BS4 bikes. These kits are to be used with models that use carbureted unit construction engines (UCE). With these kits, users can expect enhanced protection of critical components in the long term. Let’s see the details.

Royal Enfield E20 Conversion Kit

With the E20 conversion kit for Royal Enfield’s BS3 and BS4 bikes, the primary objective is to prevent possible damage to critical fuel system components. As has been widely reported, the ethanol in E20 fuel can cause abnormal wear and tear in bikes designed to run on gasoline.

Royal Enfield bikes are E20 compliant from 2020 when BS6 norms were implemented. The potential risk of damage from E20 fuel is for bikes that were manufactured before that date. Royal Enfield’s E20 upgrade kit is for the older models of the Classic 350, Bullet 350 and Thunderbird. Kit includes replacement parts such as tubes, seals and O-rings.

These are designed to work with E20 fuel, reducing the risk of potential damage or blockage. For the BS4 model, the E20 upgrade kit is priced at Rs 1,700. While there is no dedicated E20 conversion kit for older 500cc Royal Enfield bikes, some of the components made for older 350 bikes can be used for 500cc bikes as well.

With official E20 conversion kits now available, users can expect better compatibility and durability than aftermarket E20 kits. Apart from providing better protection for the engine and fuel system components, the official E20 kit can also improve the everyday experience of the users. For example, the kit can be useful for BS3/BS4 bikes that may face problems like rough idle or stalling on throttle application. It may also be useful for problems such as difficult cold starts.

RE E20 Conversion Kit Availability

Although the E20 conversion kit has been launched, it may take some time to reach all Royal Enfield dealerships in the country. Users who want this kit can contact their dealer to check if the E20 conversion kit is available. These kits are likely to be in high demand, which may impact availability at authorized dealerships. Users may have to spend some time at the service center to install and fully calibrate the E20 kit.

It is reassuring to know that Royal Enfield is offering E20 conversion kits for its BS3 and BS4 bikes at reasonable prices. Reports of potential risks such as rubber rot, metal corrosion and clogging of fuel systems have caused considerable concern among users. With the official kit now available, users can have peace of mind.
