MotoGP vs WSB Weight Issues


The 2016 weight regulations for a MotoGP bike is that the machine cannnot weigh no less than 157 kilograms, while a World Superbike shouldn't go lower than 168 kilograms. This is a big difference, and is born from the fact that a MotoGP bike is bespoke for the job of racing. While a 1000cc sportsbike are getting ever more sophisticated, they still have to hit a price point, hence why we're not seeing the level of exotic materials that we do in the MotoGP paddock.

Weight is saved in virtually all areas of a MotoGP machine, with almost a free rein offered in terms of materials used (the most significant restriction is over the use of carbon fiber wheels, which is a no-no in both racing series). - although Dorna then go and stick on about two kilos of cameras and broadcasting equipment The lack of restrictions helps in both the engine construction and all areas of the chassis. With money almost no object in MotoGP, cost is a real focus in WSB.
Frames have to be based on heavier production units, less and less is able to be done to the bottom end of the engine, superbikes have to use steel brakes as opposed to carbon fiber brakes in the MotoGP, and given the lighter weight limit there's less reason to delve into the box of unobtanium to fashion something special up.

But if you think that a modern MotoGP bike is light, think again. 500Cc two strokes, what with their simpler configurations, were hitting the scales at around 135 kilograms. The 2001 Honda NSR500 was down to a fighting weight of 131 kilograms. A lighter engine means the chassis has to do less work for the same effort, so weight could be shaved from the frame and swingarm accordingly. Components, broadly, reamin comparable to what they'd weigh now-a-day.Tag: MotoGP WSB Weight Carbon-Fiber Technology Development Racing Materials Parts
