The F55 front brake balance beam is the one that came fitted to the 2751 when I acquired it.
We have no way of knowing whether this part is original to the bike or not, possibly not as it’s showing no signs of plated finish.
To my knowledge, these were not drilled at The Works and Grey Flashes were dispatched with regular undrilled items.
We cannot assume this part is original to the bike. But it has been on it a very long time, has period lightening modifications and, as such, is a valuable part of the bike’s history. It has been prepped prior to being dull chromium plated.
