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 Supersport 600 Championship, I decided to fully concentrate on tuning and building circuit engines from 2010 onwards. Since 2015, colleagues Frank brouwer (also former driver and team manager of the IDM team swpn) Joop Rijntjes and my father Bernd Ahnendorp have joined. With this small team, quality and thinking along with the customer come first. Over the years, we have therefore been represented in every championship, from hobby to national championships to world championships. In addition, we offer service and maintenance for all Japanese engines. Through this website I would like to give you a small impression of what Ahnendorp Tuning can do for you.
