Description
The Boyesen system consists of 4 sheets made of fibreglass.
The smallest are the ones located at the top, these are usually thinner to favour the acceleration and filling of the engine at low revs.
The thicker ones, on the other hand, work at high revs to provide greater flow to the engine.
This system achieves greater efficiency, much faster power delivery and more energetic power delivery at all engine speeds.
Suitable for :
- KTM 50 Pro LC 01-08
- KTM 65 Sx 98-08
