andy m Posted March 14, 2008 Report Share Posted March 14, 2008 I remember reading about them years ago. Also when I was at college back in the day we did a project on his idea for the long swingarm etc. Good bit of film. Quote Link to comment Share on other sites More sharing options...

swooshdave Posted March 14, 2008 Report Share Posted March 14, 2008 thats a good bit of footage of the silk has anyone got a picture of this bike or even a bike the frame looks very much like my mc laren suzuki trials bike many thanks for finding it cheers ! Do you have a picture of your bike to share? Did any of the trials bikes have a jackshaft to get the drive sprocket closer to the swingarm pivot?

michaelmoore Posted March 14, 2008 Report Share Posted March 14, 2008 Meney TY250 with forward pivot and disc brake on the transmission countershaft. Concentric sprocket/pivot doesn't eliminate anti/pro squat effects in the rear end from the chain pull, but it does change them from the conventional setups. John Hemingway's McLaren Suzuki at the 1971 SSDT: cheers, Michael Quote Link to comment Share on other sites More sharing options...

toofasttim Posted March 15, 2008 Report Share Posted March 15, 2008 While on the subject of British bikes that should have made it (this could be a long posting) who knows what happened to the Mickmar engine? Quote Link to comment Share on other sites More sharing options...
martinm Posted March 15, 2008 Author Report Share Posted March 15, 2008 While on the subject of British bikes that should have made it (this could be a long posting) who knows what happened to the Mickmar engine? A friend of mine visited a very old established motorcycle dealership in the Birmingham area about 3 years ago. He was given the run of the place, and found loads of new Mickmar trials engines lying around in their basement......most of which had been robbed of the Bultaco components the engine used.

robin m. s/c Posted March 15, 2008 Report Share Posted March 15, 2008 I think the rider of the silk on youtube is Duncan McDonald as he made the ealry chassis for it. My dad Alan Morewood did quite a lot of development on the Silk. The chassis changed to a more conventional one and the engine got developed further. My brother Davy rode it in an A class champ round in approx 1980 / 1981. Think it was at Brimham. Even though the chain tension was constant I remember a tensioner was added as without it it seemed lumpy / jumpy when riding on tickover / very slow. The gearbox was very confusing. It had a conventional gear lever and then an extra one for high / low ratio thus giving it eight possible ratios. There must be some pictures of it in my dad's or brothers scrapbook Quote Link to comment Share on other sites More sharing options...
michaelmoore Posted March 15, 2008 Report Share Posted March 15, 2008 Is that your father pictured in Morely's Spanish trials bike book with his Bultaco? Is that you or your brother there with him? cheers, Michael Quote Link to comment Share on other sites More sharing options...

michaelmoore Posted March 16, 2008 Report Share Posted March 16, 2008 It is the picture identified in the book as Alan Morewood with his Bultaco. It seemed unlikely that the English trials scene would be overflowing with people of that name, but then there are a few Michael Moore's in the world so I thought I'd ask him since he mentioned it just in case he had a cousin with the same name or something like that. Page 41 opposite the photo of the Miller Highboy frame. cheers, Michael Quote Link to comment Share on other sites More sharing options...
michael_martin Posted May 1, 2008 Report Share Posted May 1, 2008 There is a Talon Mickmar Trials Bike in Sammy Miller's Museum. John Close the Cotton works rider who rode Mickmar for a season or so also has some Cotton Mickmar stuff. Michael Martin (i.e. Mickmar himself) is still alive and kicking and does the odd talk about the engine to motor cycle clubs, etc. Quote Link to comment Share on other sites More sharing options...
ninefives Posted June 20, 2012 Report Share Posted June 20, 2012 There is a Talon Mickmar Trials Bike in Sammy Miller's Museum.

Michael Martin (i.e. Mickmar himself) is still alive and kicking and does the odd talk about the engine to motor cycle clubs, etc. Long dead thread but.... I built one of the Mickmar bikes and rode it for a season in '76. Mike Martin and George Sartin provided the parts and space at the Talon workshop in Yeovil. We used a Sammy Miller HiBoy frame and Honda tank. Another guy (Mike) also built one, chrome or silver tank if I recall. Quote Link to comment Share on other sites More sharing options...
