From a press release:

Superside engine using Catalytic Converter

Reduced emissions from Superside race engine

Another step forward in technology for Superside machines was used in the testing sessions in Cartagena with the first international look at the new Rennteam Eilers machine.

The machine uses the excellent new Suzuki GSX-R1000 engine, but with a specially designed catalytic converter that reduces exhaust emissions. This is a unique for motorcycle sport, and uses the catalytic converter together with fuel injection to obtain to high horsepower requirements for Superside.

Dieter Eilers, together with the Rennteam Eilers team have been working since the middle of last year to combine the new Suzuki engine with the catalytic converter from HJS. They choose to use the smaller but newer 1000cc engine partly to comply with proposed rule changes, but also to add fuel injection to their engine management plan.

“In the future motorcycle sport will only work without pollution. I think that it will move forward like car racing. As in the past, Superside will lead these major changes with technology in the paddock”, commented Dieter.

Eilers tested the new specification with his two passengers, Helmut Engelmann and Andy Kolloch in Spain with good results, getting down to a 1:48.544 at the two-day sessions.
