When the rules limiting the number of engines each MotoGP rider is allowed to use were first introduced, their usage was followed hawkishly. After pressure from veteran US journalist Dennis Noyes and myself, and with the assistance of Dorna's incredibly efficient media officer, IRTA and Dorna were persuaded to publish the engine usage charts. These were pored over constantly, searching for clues as to who might be in trouble, who may have to start from pit lane, and who would manage until the end of the season.
How the world has changed since then. Since 2010, the first full year of its application, engine allocations have been cut from six engines a season to just five, but despite that, the manufacturers are getting better and better at building incredible reliability into high horsepower engines. All eight Factory Option Honda and Yamaha riders completed around 9,000 km in 2014, using just 5 engines in the process. In the case of Bradley Smith, he raced for 9416 kilometers using just four engines, an average of 2354 km per engine.
The introduction of the engine reliability rules may have pushed the costs up at first, as factories rushed to modify their engines to suit the new regulations, it has worked well since then to help cut costs. No longer are engines crated up after every race to be flown back to Japan, there to be stripped, measured, tested and rebuilt, then flown back to Europe again ready for the next MotoGP round. Perhaps more importantly, the factories have made real technological progress in the field, Shuhei Nakamoto, Kouichi Tsuji and ex-Ducati Corse boss Filippo Preziosi frequently praising the rule for the advances they have made. It is exactly the kind of technology which will find its way into road going motorcycles, allowing more power to be extracted while retaining reliability. There is good reason to believe that the latest generation of big horsepower road bikes have been made possible thanks to advances in materials and lubrication technology which have made it possible to produce that power without sacrificing reliability.
