In MotoGP, very curious things happen: if you observe a motorcycle (Ducati, Aprilia or Suzuki) that comes out of the pits with a white front rim, you shouldn’t be surprised if it turns purple when it is engaged on the track at full speed. .
At the Sachsenring we reviewed precisely this phenomenon, after having briefly noticed it already in Barcelona: we should not be surprised at all because it is the result of the great work that Marchesini’s technicians have done on MotoGP wheels.

What is it about? The application of new nanotechnologies in the paint of the rims that allows to reach two important objectives: first – to reduce the weight by 70 percent, compared to a traditional treatment; second – to generate a refraction of 80 percent of infrared rays and 30 percent of those generated by the disc.

Result? That the surface of the rim changes color and turns from white to shades of purple or blue when nanotechnologies come into action thanks to which it is possible to protect the wheel and, therefore, the rubber that will be helped to be preserved from possible overheating.
It is evident that this solution can be particularly useful in racing to reduce the degradation of the rubber in particularly hot events such as those of the summer season.
And since the Sachsenring is the most demanding track for Michelin tires, with the left side shoulder undergoing a super job with very low grip, it shouldn’t be surprising if you experiment with all the solutions to limit wear problems.
We can be proud that innovations like this are being proposed by Italian companies such as Marchesini, the rim manufacturer that is part of the Brembo galaxy, a sign that research remains one of the aspects that lead to investing significant amounts in motorsport.
