Plug & play on PX125/150 frame; no frame work required

Note: Exhaust control angle & system selection

The resonance system worksoptimally with exhaust control angles from approx. 180° (typically 180-188°). This provides the best conditions for powerful charging in the upper rev range.

The exhaust can be run at <180°, but does not fully exploit its potential (slightly less peak power/overrev).

Box systems such as the BGM1010TR2 are often the better choice at clearly below 180° - more pressure from the rev range, very early response.

Tip: Reliably measure the timing angle (key words: piston stopper/wheel disk) and adjust the peripherals (carburetor, ignition) to the target range.
