Viessmann is backing German motorcyclist Stefan Bradl for the second year running.
The company is backing the 21-year-old who is riding for the Viessmann Kiefer Racing team as part of its international youth sponsorship programme.
He has won four out of eight races and claimed two other podium finishes so far this year. At the half-way point in the season he currently tops the Moto2
