what is real world solid proof advantage of box style head steady and other more exotic ones over the early flat plate unboxed style? on 72 commando that is..
Which is how they got the nickname "Bendy" I guess. (it's not heard so much these days though).When I was a kid I had a mk2a commando I didn't really know what isolastics were
One night I was hacking down a dual carriageway into a tight lefthander and the bike just bucked and shuddered it seemed to leap off the road any way I needed both lanes to get round that bend
The next day I was looking at the bike and noticed how much the engine moved when I pulled the back wheel about!
I removed the tank and found both the triangular plates that hold the rubber bobbins were bent outwards
Both the bobbin threads were stripped out of the frame,it looked like they may have been ataldited in!!
I re made the plates out of 1/4" thick steel, this was with an interstate steel tank,I had no clearance problems
They are definitely bendy if not set up right!Which is how they got the nickname "Bendy" I guess. (it's not heard so much these days though).
I too have not tried a commando with the Dave Taylor type head steadyAn ignoramous asks: as someone who's never ridden a Commando with a DT-type head steady, and isn't in a position to experiment by just buying/making one and trying … I'd be grateful for an explanation of how it is 'better' than the 'Norvil' style. I remember following Mike Taglieri's experiments donkey's years ago, so maybe I've just forgotten this detail, but … Trouble is, I understand the purpose of the Isolastics to be to stop any appreciable 'sideways' movement by the engine, limiting movement to a vertical plane in line with the length of the bike. And, when I look at the DT head steady, it seems to encourage sideways movement, since the rose joints form a bar that pivots around its attachments at each end: to my understanding, this means that the engine-end of that bar must 'swing' around the head-steady end, since that end is fixed in relation to the frame. So, laterally, the bar 'becomes' shorter and longer as the engine bobs up, down, backwards and forwards. Is that right, and is it simply that the effect is negligible, or what? TIA
