It must be appreciated that no two bikes, even identical models from the same manufacturer, may or may not deliver identical fuel mileage figures. Suffice it to say that the reasons are not the issue here. The quest is to chart the figures for the respective bikes, taking the utmost care to ensure that every effort was made to remain consistent in riding styles and all other aspects that would have an effect on the final results.
  
Since the bikes were ridden together, the method employed was to fill the fuel tanks to the brim before the start and at the end of the run, topped up to the previous mark. This was the best way to preserve accuracy rather than depend on the fuel taps, which could not be verified visually. All the bikes were tanked up at the same outlet, and the fuel dispenser was cross-checked for accuracy.
  
The route distance was measured by accurate measuring equipment rather than the bikes' odometers, which could have introduced discrepancies from bike to bike.
  
Riders were also switched from bike to bike at specific points to further spread riding style equally. Engines were fired up at the same time and the end of each run they were switched off at the same time. Tyre pressures were checked on all the bikes and set to the manufacturers' recommended figures. It was made certain that the engines were tuned to manufacturers' Specifications and no fuel saving adjustments or additions were made. No special riding techniques were employed to try and achieve a test result other than what would be possible under normal riding conditions. The bikes were serviced and the engines tuned to the manufacturers' Specifications.
  
The test routes were each over about 120km, once in the city and once on the highway. Two sets of runs were done to bring a real world authenticity to the results. The results though have been charted separately for the city and the highway test, since the tests were run on their own on succeeding days. Worthy of mention here is that the city route was through rush-hour traffic and included many sections with traffic signals, and although there were some stretches where a freer run was possible, these were not too many. The average speed of the city run worked out to 25kph, which is representative of Mumbai traffic. The highway route was not an expressway run where constant speeds in a high gear could be maintained over the majority of the run but involved typical traffic conditions of a single carriageway where stop-start conditions are also frequent.
  
This combination of real world conditions was chosen to ensure that the results would be abundantly representative of the Performance, Fuel Efficiency-wise, of all the bikes in general. More important, these figures represent what we believe you, the reader, would get in day-to-day use.
  
The ten motorcycles tested represent the broad choice available to the customer in the Indian market today. New and improved models are being introduced frequently and our regular road tests of those models will carry the Fuel Efficiency figures that are achieved by our established testing methods.
