Models Not Currently Counted as Regular Retail Options
Honda CB300F Flex Fuel
The Honda CB300F Flex Fuel was launched as an E85-compatible motorcycle, but Honda removed the model from its Indian line-up in 2026. It should therefore not be treated as a currently available new motorcycle. CB300F discontinuation details
TVS Raider 125 Flex Fuel
TVS demonstrated a Raider 125 capable of operating on blends between E20 and E85. However, the flex-fuel variant was showcased as a technology demonstrator and has not been verified as a regular retail model. TVS flex-fuel technology report
TVS Apache RTR 200 Fi E100
TVS previously introduced an ethanol-based Apache RTR 200 Fi E100. However, it is not part of the mainstream current retail line-up and should not be confused with the regular petrol Apache RTR 200.
What Is E85 Flex Fuel?
E85 is a high-ethanol fuel containing up to approximately 85% ethanol and 15% petrol. The exact ethanol percentage may vary according to standards and market conditions.
A flex-fuel vehicle can detect the ethanol-petrol mixture and automatically adjust:
- Fuel-injection quantity
- Ignition timing
- Air-fuel ratio
- Cold-start strategy
- Engine-management parameters
- Emissions-control operation
Flex-fuel models also use ethanol-resistant components, including:
- Modified fuel pump
- Ethanol-compatible fuel lines
- Revised fuel injectors
- Additional or upgraded fuel filters
- Corrosion-resistant seals and gaskets
- Flex-fuel engine-management calibration

- Your daily commute is predictable.

- Confirm warranty coverage when using E85.
- Check whether E85 usage affects service intervals.
- Verify dealer inventory and delivery period.
- Obtain the final on-road price.
- Never install an unapproved conversion kit.
- Never assume an E20 vehicle can use E85.
