Isolastics Mk3 vs Mk2

Phil your report is as interesting as an ambush to me in a mine field. Those few with the triple- point-link helpers by radius rod or swash plate solved the 750 surprise dancing, so asking what feature makes the MKIII so secure from the factory? I've put adjustable iso's in my otherwise factory Combat Trixie, [no links] which temped me into 'fast' turns till about mid way or on lifting up exiting can suddenly go nutzo so I have given up pressing Trixie to maybe get a straight line speeding ticket but definitely not wreck-less driving. On Peel they have to catch me first, which is my life passion on her.

The MkIII is not that different, just refined and with a little green button which when pressed makes the engine go vroom vroom vroom!
White man's magic!!

When it first appeared in March 1975 I nearly vomited, I was horrified. Even blinkers (turn indicators) on a Norton was an anathema to me. My Combat had them and I wanted to saw them off. But thought better of it.
I required therapy to get over the revised primary chain case, left gear change, one down three up, and rear brake on right side, to name just a few horrific variations from what I knew. Then there were the bean can mufflers! For that I went straight to hospital!!

No, it is a very good machine with appropriate mods and upgrades. It doesn't go like my fierce Combat did.
Hobot, who obviously sleeps with his beloved Trixie would beat it. But I gave up doing standing quarter miles some forty years ago.

The MkIII offers a relaxed but torquey engine with upgraded creature comforts. And every where I go, folks crowd around and ask about it. Especially when I push that little green button. It will go on to be one of the classic Nortons ever made. Even now they are becoming scarcer and scarcer if you want to find one for sale.

Thanks, Phil. You're a good sport.

If you can kick Trixie out of bed for a moment, who asked anything about Mk III security from the factory? I said I assumed the stiffer isolastic rubbers were to improve handling. But I am only guessing. I do know the rear wheel will not flex sideways when the bike is on the centre stand. And it makes sense that this would eliminate the "bending" sensation of the frame. Also seemingly add some extra slight vibration issues, as everyone in here has commented.

As I am new in here, can you give me a run down on what Trixie is? Apart from being good in bed.
Also Peel. I don't know Peel.
There was a Emma Peel in an English TV series back in the 60's

In those days, Biscuit Boy was just learning not to poo his nappies. I hope you were a bit older than that or Pete V and myself will need to give you some serious educating. )

Hey, don't drag me into this, I have my own wars to deal with.

Anyhow, I have to MK3 "type" iso's, possibly the models only saving grace, and although i canoot say as to the durometer reading of the rubber, I do think that whatever you use, fresh is best.

For what it is worth, in combination with the PR headsteady, my bike feel tight AND smooth at the prescribed rpm's.

As a pain as it is to change out from stock, front and back, it is well worth doing..
