Bottom Fork Yoke for Plunger A10 with a sidecar fitted

[BrianR]

I am new to this forum and I am looking for information about whether BSA ever produced a different bottom front fork yoke for a 1951 Plunger A10 to change the fork angle when a sidecar is fitted.

Any information would be much appreciated.

I can't help you with that question, sorry, but if you are stopping, why not head over to Introductions and post a bit about yourself and your motorcycle experience.

Also sorry, my plunger Ten pulled a chair for most of its life I think but I have nothing to compare it to so no idea whether it's standard, or even originally part of the same bike.
Intro and pictures always enjoyed if you feel so inclined.

G'day BrianR, 
My parts list only shows a std pair of yokes bar a slight change in 53 to the top yoke for headlight mounting.
Cheers

I also own a '51 that pulled a chair around for many years, the only difference I've noticed is the addition of a hole for the steering lock.

 Its a bit of a minefield, as the same geometry can be used on different models, but under different part numbers depending on application. The steering lock is a good example. Plunger frames only have the lock towards the end of production. The frame changes slightly with a plate for the lock operating plunger added to the steering head. So here a late type top yoke with a hole for the lock mount can be used on an early frame, but without a plate the lock is useless. The part number and forging change, but the geometry is the same.

Conversely top yokes with locks for Plunger and S/A Models look similar, but as they have different forging numbers and applications they can't be a simple swap in my estimation. The bottom yokes are distinctly different.

 Have a look at the Draganfly online catalogue and take your pick.

 Swarfy.
