ROADHOLDERS .

shift it if its not ' Commando ' . :wink:











:|

:shock:



Even Karruthers / roberts had a seely TZ 350 at one stage . The Confidance in the Norton front end , and Brake Availabiltiy exceeded that in the drum brake whizz bangs .
till the Forign pilots educated them . think theres a picture of the renolds Hailwood 500 honda with the Dunstall dual disc ROADHOLDERS . So they cant be to hopeless .

No 18 Look like Pat mahaney just before his accident that put him in a wheel chair,he was a very quick rider especially at Brands Hatch and Lydden Hill,shame!!
The Kawasaki with a large top tube and Twin dunstall discs is the Dunstall "Drain pipe",raced I think by a Leicester Racer called Jhonny Woodhead,with some success.
He was a great guy, a real life and soul of the gang and could tell a great story,and very funny,we still miss him,he got took out on the Lutterworth road,by an idiot overtaking on a brow of a hill that killed Jhon who was on a bike and all three in the car,

The Dunstall discs were a brillint idea,and Phill Read tried them but soon took them off,I was in coversation with him once and asked what were wrong with them and he said they worked well for short races but the heat from the discs transferd to the fork bottom legs and overheated the fork oil,also the brake pads were too small,as compared to the AP lockheeds pads.
Novill do a small conversion to the Roadholder that improves them a lot,RGM do a covenant damper conversion that also improves the fork actionn.Maxton do a conversion to the roadholder where they fit CBR Honda fork cartridges inside the damper this I have been told is the best method.
The problem is the roadholder only damps one way properly but not fully damping two way.

The biggest problem concerning suspension system is the rear end,people use cheap shocks.then complain that their bikes do not seem right,the problem is that cheap shocks only damp one way !!.the best ones like IKON or Falcon or Ohlins work two way,please if you want good handling and steering buy some good ones with tri rate springs and more adjustment.the improvement will shock you (no pun intended)but for a great improvement try Hagon, they are good,but you get what you pay for,they are ok for quick road work,but for me contact Falcon and give them the bikes weight,and your weight and your intended use,they will make you a perfect shock for your bike,the handling and steering will improve dramatically.

The Dunstall disks were too small and thin.
In the light of more modern knowledge.

My guzzi has its calipers forward of the forks.
Guzzi said they give better braking with the calipers trailing than leading.
And cools the calipers better...

Some say this gives the forks more pendulum steering effect.
And some manufacturers think it looks better with the calipers behind the forks.
Swings and roundabout ?

Note the Only Thing the Convent kit does is put in 2" long collars to extend the top bushes so holes get covered that stop the top out clank of Roadholders, nothing else and often found at bottom of forks for a bit more mass to slide up/dn. Helps noise if lifting forks to move in a shop or pulling wheelies quieter. Thanks for dual brake heating history lesion.
