Bonneville America Forums Forums Off Topic Discussion Forums Lounge Is a Speedmaster considered to be a Bonneville?

I think the Hayes Service Manual has a good description in their little history of the Modern Triumph. The America and Speedmaster are considered "derivatives" of the of the Bonneville since they use the samwe basic power plant. Marketing can do as it will with names as long as the engineers know they have a good solid product and don't let the marketeers mess with it.
