Double 5 Kent & North Kent Trials Combine
Good article. It appears that the small dimensions of the engine allow it to be installed in the stock pro frame. It claims that the weight will be only slightly more than the 2T. Extensive testing is ongoing. Will be interesting to see it.
Have you a photo of the engine in the frame/chassis
There were no pictures in the article. The digital magazine is very good and covers the entire motorcycle spectrum. It is available to anyone.
