Well we finally did it!!! After years of hearing 'Dont forget aboutthe little RZ's, we finally built a custom aluminium twin sparframe for the RZ350/250 engines. Not only that, we designed acompletely new bike using our new frame and our newly designed setof bodywork.. hence the Costin 535 was born!

This bike uses the popular Banshee 535cc big bore kit with theRZ/RD bottom end. We have designed this bike to be an everyday roaduseable and registerable motorcycle. It uses previously compliedcomponents such as Yamaha R6 suspension/wheels and brakes, Ducati1098 headlight and 'E' marked indicators. See the parts list belowfor a full rundown of the Costin 535 components!!

Alternatively we can build you the same motorcycle with a standardRZ/RD motor or anyone of the Banshee big bore engine kits..

Orif you prefer, we can sell you just the frame with or without thebodywork for you to start your own build. You can purchase as muchof the bike as you like..

These big bore engines use modern 2 stroke technology and the frameshould be no different. Why house it in a compromised frame whichwas designed for another engine?? Our new 535 frame is purposebuilt for these engines!!!!
