RGB500 replica engine made by Ton Spek. A few years ago it all started with an CNC alloy crankcase.
Here we have a piece of art made by Ton Spek, a CNC Suzuki RGB500 crankcase! First he made a 3D plastic model and after that a CNC alloy one. The original RGB500 crankcases are made of magnesium and are known for leaking and oxidation, so this is a perfect solution.
