My name is Swen Ahnendorp and I would like to introduce you to my company; Ahnendorp Tuning. After years of successfully racing at the ONK and IDM level, culminating in the Dutch Champion Supersport 600, I have decided to fully concentrate on tuning and building track motorcycles from 2010. We also offer service and maintenance to all Japanese motorcycles. Through this website I would like to give you a small impression of what Ahnendorp Tuning can do for you.

Race to perfection


We specialize in Yamaha, BMW and Kawasaki for your complete engine tuning. This does not mean that we cannot help you with tuning another brand of engine.

Repair and maintenance

Ahnendorp tuning is not only tuning, but also offers maintenance for all Japanese engines. Winter service, summer service, tires, repair or changes to your engine no problem.

Very well helped by the friendly owner!


You are still a customer there. Super friendly and very competent. Even in busy times they make time for a personal conversation.


Really good advice  👍
