Tuning guide, M8 Touring 2017–2026

Tuning requirements depend on your baffle choice and engine setup. Before installation, contact Forsch with your model year, engine size, baffle choice, and any intake, header, or engine modifications.

Baffle	Tuning guidance
Angry II	Generally no tuner is required. Contact Forsch or your dealership to confirm tuning requirements for your specific setup.
Angry III	For 107 engines, the current product specification requires Stage 1 plus a tuner. For 114-and-up engines, tuning is recommended for full benefit. Contact Forsch or your dealership to confirm the appropriate setup.
Angry V	The current product specification requires a tuner for all engine sizes to maintain correct air-to-fuel ratios. Consult Forsch, your dealership or a qualified tuner before installation.

Safety note: Confirm installation and calibration requirements before riding. If the motorcycle runs abnormally or displays a warning, stop safely and seek qualified assistance.
