General description

Proudly holding the motorcycle A2 driving licence, seen the dream motorbike at the dealer, distributor - this machine HAS to be it! Small catch: the standard power for the tiered licence is too high. Is the dream over? On the contrary, with alpha Technik power, performance reductions, the motorcycle dream immediately becomes reality!

With alpha Technik restriction kits, motorcycles of all power, performance classes become more interesting for the motorcycle rider, as almost any desired model can be restricted to the required power, performance of 25 kW or 35 kW. However, special conditions apply to holders of the current A2 driving licence. The power, performance weight of 0.2 kW/kg and double the original output of the series vehicle must not be exceeded.

A lot of know-how goes into the development of power, performance restriction. Essential factors must be taken into account: on one hand, legal regulations such as exhaust, noise, and power, performance measurements according to the latest EC directive. On the other hand, maintaining optimal rideability and homogeneous power, performance delivery as unchanged as possible.
If all requirements are met, a component certificate is issued by the technical service. Until then, it is a high development and measurement effort, which is not immediately apparent from the sometimes inconspicuous restrictor plates and throttle stops.

25 kW Restrictions:
Before the new driving licence regulation, which came into force in spring 2013, new licence holders had to manage with 25 kW for 2 years. Due to its extensive range, alpha Technik still offers numerous 25 kW restriction kits today, which can consequently be used by A2 licence holders. All 25 kW restrictions work mechanically; no intervention in the electronics is necessary. The power, performance reduction is achieved by installing specially designed restrictor plates in the intake tract, or with throttle stops.
