Expert Tip
Tuning & Road Legalization: Please note that a control unit with an unlock for up to 70 km/h can affect the original road legality (COC) of your vehicle. Installation constitutes a structural modification. Inform yourself about the applicable legal regulations for use on public roads before installation. The achievable top speed also strongly depends on the remaining capacity of your battery, the motor, and the general condition of the vehicle.
Frequently Asked Questions about the Product
Will my chopper definitely reach 70 km/h with this controller?
70 km/h corresponds to the software-enabled unlock of the controller. Whether this speed is actually achieved on the road depends on the motor power, the condition of the battery (voltage), your rider weight, and external influences.
Is installation complicated?
If your vehicle has the suitable connector version (555D), replacement is pure Plug & Play: Unplug the old control unit, plug in the new one. Make sure to neatly store the cables again, protected from splashes.
Will I lose my road approval due to the upgrade?
Generally, yes. An increase in the design-related top speed, without a new individual acceptance (e.g., by TÜV), leads to the expiration of the operating license for public road traffic.
