Really surprised how small the Plus Four fuel tank is compared to recent classics which carry in the order of 52-55 litres. I can understand MMC taking advantage of the excellent fuel economy but not at the cost of reducing real life range to such a degree.
To be fair I can get a miles to empty figure of 365 miles on the surprisingly accurate readout on my Roadster with full tank under average driving. 39 litres would give you similar at 45 mpg, but how careful do you have to be to average that?
