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

This bike uses the popular Banshee 535cc big bore kit with the RZ/RD bottom end. We have designed this bike to be an everyday road useable and registerable motorcycle. It uses previously complied components such as Yamaha R6 suspension/wheels and brakes, Ducati 1098 headlight and 'E' marked indicators. See the parts list below for a full rundown of the Costin 535 components!!

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

Or if you prefer, we can sell you just the frame with or without the bodywork for you to start your own build. You can purchase as much of the bike as you like..

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

Check out the build quality!!! This bike has been built to production standards!!
