CFMoto 675SR-R / SR / NK Tuning

Stage 1 tuning for the CFMoto 675 retains the stock exhaust and air filter, making it a cost-effective and reliable upgrade. The key improvement comes from a custom ECU remap, which refines the engine’s parameters. This results in a cleaner, more stable air-fuel ratio across the rev range, improving throttle response, and enhancing overall rideability. While peak power gains are modest, the smoother delivery and improved efficiency make the bike feel more responsive and refined. It's an ideal option for riders wanting better performance without the hardware changes.

Stage 2 tuning for the CFMoto 675 is designed for bikes fitted with an aftermarket exhaust and high-flow air filter. These upgrades increase airflow, and the ECU is custom-tuned to match—resulting in a smoothed air-fuel ratio that supports the increased volume of air. This ensures optimal combustion, sharper throttle response, and improved top-end performance. The engine runs cleaner and more efficiently, eliminating lean spots and hesitation caused by bolt-on mods. Stage 2 delivers a noticeable performance jump over Stage 1, making it ideal for riders seeking more aggressive power without sacrificing reliability. This setup improves power by around +6 HP and +6 Nm

The Stage 1 & 2 transforms the 675 into a sharper, more powerful machine, ideal for track use and spirited road riding.
