Big Bore Kit 1070cc "S" Touring

Plug & Play Kit.

No matter which one you choose - you`ll have lots of fun. Guranteed!

1070 ccm dispacement, 80 PS approx. and giant torues between 90 and 116 Nm argue for themselves.

In addiion to our standard kit, that is established over the years we now have the "Touring" variant equipped with slightly shorter con-rods, for those who look for a powerful smooth riding performance and a plus of torque in the loer revvs.


This ultimate Big Bore Kit for tourers and long-distance travrellers deliveres powerful torque "off the cuff". It persuades in every situation with a quiet engine running and tolerates a bad quality fuel down to 95 octane approx. without knocking.
