Not availabile till April but speaking to DT they have 5 Prototypes still running at the end of the year and here is what he said 'I used less hard alloy in the lower link to see what would happen. It did not work, so 3 of the bikes are running with higher strength right now. Same frames, just new lower link and bolts. Not many companies have 5 protos still running at the end of the year, the bikes have obviously been modified where needed but he was saying that every test rider has reported good things for the DW DHR. I think this is a testament to how commited Turner are at bringing out a bike that will not only Race well but will last, something i think you should expect when you pay all that money. There are a couple of manufacturers out there that produce bikes without proper R&D and this is well known in one big American company no names mentioned.
