Vee Two HRC-copy gearboxes
My name is Andrew Cathcart, and I am the General Manager for a company called Vee Two in Australia.
Vee Two were commissioned by a European Team racing a pair of HRC RC51's in one of the European National Superbike Championships to manufacture 10 sets of HRC gearboxes and some camshafts with slightly different duration and overlap - to the team owner's race engineer's design.
The transmission components that we delivered (reverse engineered from the HRC units that Vee Two was provided by the team) worked brilliantly, and it was decided that we would make additional batches. This final batch of 20 was uncompleted when Brook left the company to retire in 2005.
Now that Brook has come back out of retirement, and the two of us have bought Vee Two back to specialise in Ducati race engines and restoration, we are going to finish off this last batch along with the range of Ducati race transmissions that we are manufacturing for our customers.
The file shows me that according to the HRC catalogue that was provided with the sample HRC transmission set (presented in the blue velvet lined storage box), all gears are accounted for aside from the 16 tooth Mainshaft and corresponding 33 tooth 1st gear.
Every other gear apart from 5th (which has only one option - 26T on the mainshaft, 30T on the counter), every other gear has two options, giving a very versatile range of gearing.
I've attached some photos of a single set of parts as they are right now. We have manufactured them out of EN39B Case Hardening Steel, and if there is enough interest we intend to finish the final process of heat treatment along with the next batch of our close-ratio Ducati gearboxes.
