1. The first polishing
Once the alloy came back from the water blaster it was just a matter of time before we gave the polishing a go! Curiously the water-excluders (brake plate covers) on the hubs are of two different materials. Chrome plated steel on the rear and aluminium on the front. Not sure why. The alloy plate polished up well and the top triple tree even better. As on other parts the corrosion has left some deep pitting which it is better to ignore but we are very pleased with the result. Our first few attempts at the engine covers have not produced the sort of mirror finish that can be achieved on Japanese and British bikes - is this a difference in the Czech aluminium alloy we wonder?
