Hi, I am looking to buy the Guerilla 450 apex variant, but current fuel norms have got me worried about E30 petrol, as I believe current bikes are not compatible with the same. Should I halt my purchase or go ahead with it?

For the short to mid-term, E20 will be the current baseline blend of petrol available on a nationwide scale. Speaking strictly about material compatibility, E20 machines should be able to handle higher blends with the fuel tank, rubber seals, gaskets and hoses all ready to support the higher blend. What will need recalibration is the ECU to handle the higher ethanol content in the fuel, which is something that will have to come from the manufacturer.
Be prepared for a drop in fuel economy because ethanol's energy density is much lower than petrol, although ECU recalibration will mitigate this to some extent.
