Going back to earlier posts, all HDs have had Efi for years. Indian Enfields are still available with carburettor power plants, but only in those markets where the Efi is not a requirement to meet emissions regs (so not EU then).
Tax band? Suggest you look at the motor bicyle / tricycle VED rates - you'll find them on DVLA's web site. CC - don't know, what do bikes pay?
The only (non-electric) new car that is free from CC is the new Fiat 500 TwinAir and has a zero rated VED...
Cheers,
