The engine covers are mandatory in racing series and recommended for everyone on the race track as well as on the road. In the event of a crash, the motorcycle usually slides on the asphalt, the expensive original engine covers are ground through and it can come to oil leakage. Also dirt and grime can get into the engine and damage it.
The engine covers are made with the autoclave process, this is the most complex process to produce carbon and leads to a very stable product. The attachment can be done via self-drilled holes at the screw connection points, but we recommend to glue the covers with heat-resistant silicone.
