Maney Stage 1 Head?

I have a book with all of the various Commando road tests through the build years.

The majority of the road tests show a top speed of a STOCK Commando of between 105-112.

The highest was at 114mph I believe.

Isolastics and Commando handling?

Nothing wrong and bad about the front iso, replacing the head stead with a rod linkage is a plus

most agree that shimming the rear iso to around 5 thou cuts way down on any swing arm movement,
while delivering some more buzz to the foot pegs, that should take care of side to side play

the rear spindle over time will cause wear in the bushings/cradle resulting again in swing arm play

the fix was first found by Heinz Kegler with his two aluminum rings with bolts through to the spindle

I also have that book of reprinted road tests.
You always have to look at what sprocket was fitted to the test bikes.
And where they did the top speed testing.

19 teeth isn't going to give a top speed over 110, unless they rev it beyond the red line. (At 114 mph, they did !!!?)
And a lot of english tests only give it a short squirt on a short bit of road - not much room to get up speed, and then no room to slow/brake.

And the Mk3 euro spec plastic airbox and mufflers wasn't as strong as earlier motors, so fitting it with a 22 tooth was just silly - it was the earlier bikes that needed the taller gearing... ??
They just didn't come out of the showroom with top speed in mind - if owners wanted that, they (mostly) had to change the gearbox sprocket.
