Welcome to Costin Motorcycle Engineering (Formerly MicoProducts).

In late 2009 with business getting busier, we decided to move into a new factory unit in the Sydney suburb of Ingleburn. . We decided to make this a fresh start so we changed our name to Costin Motorcycle Engineering. We can now make our products quicker and more efficiently.

We specialize mainly in building 500cc GP replicas using the Yamaha RZ/RD500 engine. We now also build aluminium twin spar frames for the RZ/RD 350/250 series of engines, and have as well designed and built a completely new bike using our new 350 frame and a 535cc big bore kit. The new Costin 535 (see link below).

In fact we can build a frame for any type of engine. We are currently having our custom extrusions made. We will use this for the majority of our future frames, but will still produce our fabricated sheet frames if required.
