The bigger questions
Questions a brochure cannot answer
A single bike’s mileage is the easy part. The interesting questions are about differences: between fuels, between places, between the way one rider uses a machine and the way another does. Each needs thousands of real tanks before it means anything, so we are counting in the open and showing you exactly how far off we are.
When one of these publishes an answer
Both sides of the comparison need 30 clean fills from 10 riders, on the same model, and the gap between them has to be bigger than the spread inside them. Two arms can both look busy and still be telling you nothing.
Everything is worked out one bike at a time before anything is pooled. Thrown in together, premium fuel looks worse than regular, for the boring reason that premium is mostly bought by people on big bikes. Comparing a Classic 350 against another Classic 350 is the only version of this question that is actually about fuel.
Premium costs more at every pump in the country. The claim is that it burns cleaner and goes further. Nobody selling it has ever had to show their working.
Traffic, terrain, heat and fuel all vary enormously across a country. The same machine should not return the same figure everywhere, and riders have argued about this forever without a number.
Someone doing 200 km a day is mostly moving. Someone doing 20 is mostly stopping. Stop-start running burns more, so the daily distance a bike covers should show up in what it returns.
Every rider has a pump they swear is stingy. It is the single most requested cut, and the one we are least willing to guess at.
Every tank counted here was logged by a rider on the RevRANGE app, full tank to full tank. Partial fills and missed fills are thrown out before anything is counted. How that works
