Product Details

Technical report 35 kW for Aprilia Tuono 660 and RS 660, Type: KS, from model year 2021- (EURO5), EC type-approval no.: e49*168/2013*00059*, with conversion parts (electronic power, performance restriction = Micro Controlled Restriction).

General Description

Electronic restriction to 35 kW for Euro 5 motorcycles:

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



A lot of know-how goes into the development of power, performance restriction. Here, essential factors must be considered: on the one hand, statutory regulations, such as exhaust emission, noise, and power, performance measurements according to the latest EC directive. On the other hand, the preservation of optimal rideability and homogeneous power, performance delivery as unchanged as possible.



From the outset, alpha Technik has shaped the development of power, performance modifications for new Euro 5 vehicles according to currently valid guidelines. Since the launch of the patented MCR restriction modules in 2016, we have offered you and your customers reliable technology at the highest level and at an affordable price.



The latest version makes restriction for 'ride-by-wire' vehicles even simpler, faster, and more convenient. These vehicles can now be restricted to 35 kW with absolute operational safety, without the previously used additional throttle plates (*). The newly developed control technology of the modules always ensures the correct ratio of gas and air.



The redundancy required by law is, of course, met, as is electromagnetic compatibility (EMC).

Workshop time for installing the restriction is significantly reduced; installation is faster and very easy to carry out.

A major advantage of the MCR restriction for bikers remains the full number-plate bracket of the throttle angle at the throttle twist grip – every movement towards full throttle provides propulsion!



Restriction kit features:

- Top price-power, performance ratio

- Tested quality

- With technical report

- Technical support

- Continuous range expansion



(*) For Euro 5 vehicles with conventional throttle cables to the throttle bodies, additional throttle plates remain an indispensable component for correct mixture composition – this prevents leaning out with reduced gas supply but fully open throttle bodies.
