Takegawa Honda Monkey Special
According to Mr. Minoru Hazaki [PR-contactperson for English communicating people] from Takegawa company there is a Desmo-head made for the Honda Monkey. To me it seems a Ducati 4 valve type (first generation) system. I asked Mr. Minoru Hazaki some questions (09-11-2007). When his answer gets in I will post the information here at once!
Dear Mr. Henk Cloosterman Hello. Thank you very much for your inquiry. We are the compnay specialized in mini bike engine, spare parts etc in Japan.
The head in the pics above right,
this is the smallest DOHC-type Desmo head in the world. This is not just DOHC head, but for Desmodromic structure. Of course this product is not for sale.
Mr. Hazaki forwarded my questions to the technical dpt. with the following result: This very desmohead is a miniaturization of the older type (M. Bordi designed) 4 valve desmo system (Classification = Group 5). It was produced in 2002 and displayed at the Osaka (Japan) Motorcycle show in 2003. Engine displacement at the moment is 125 cc, but it can be used on a 90 cc as well. It was developed to study the possibility to use for a Honda engine.
It's a unicum since only one ex. exists. It is not for sale because of the high production costs. Unfortunately at the moment the Takegawa cie. cannot provide me with pictures of the separate parts or parts in situ, but they will when for some reason the head has to be disassembled.
