2stroke4stroke Posted October 31, 2019 Report Share Posted October 31, 2019 Can anyone remember who made that Bantam engined bike that used the frame as the exhaust pipe? Probably in the late Sixties. Quote Link to comment Share on other sites More sharing options...

section swept Posted November 1, 2019 Report Share Posted November 1, 2019 It wasn’t only a Bantam that got the exhaust/frame treatment there was I think a Metisse with a Triumph engine where the exhaust down pipes entered into the frame lower tubes and exited just before the swinging arm. In both cases I think there would have been heat issues and especially with the Bantam. Imagine the load and stresses being put through the exhaust port, securing ring and frame connection.

The harmonics aswell. Bet they would have been interesting to clean out. Its something I've not come across before so I'm interested in the story and the thinking/ theory behind the idea.

I only recall it being pictured, with some details, in the trials column of the Motor Cycle but can't remember hearing anything further of it, so can't say who rode it or how well (no doubt somebody can). Memory was stirred during discussion about the Emme which a pal had just seen in the Neckarsulm museum.

not ron Posted November 2, 2019 Report Share Posted November 2, 2019 I think it may have been made by Eric Cheney as I remember his son Simon?? Cheney riding it in trials in the Southern and South Eastern centres in the 1970s, it probably needs to be the 1970s with the D14/4 engine.
