Twin Discs

twin discs is just another option for people to consider, I had lots of inquiries regarding a twin disc setup.
the majority of big bikes have twin discs.
 
I try to give people what they want and which I know will sell, lots of people already running twin discs on Nortons, wont sell lots but they will sell, the return on investment of longer sliders is not good, a big outlay for something that I believe will sell very few of. standard pinchbolt slider would give a better ROI.
 
Completely understand the biz end of your situation. Must say Id not be as interested
in the twin front setup as Id be in something to replace the heavier-than-a-house
rear though. A plus if it had a decent shock absorber. Lightness more than braking
power would seem the thing, the back doesnt do much on any bike anyway.
 
The only reason I use twin discs on my Seeley is that I don't like somersalting down the track when the drum brake locks, or dodging obstacles when it drags, and causes the bike to go stable. Discs are reliable, have perfect feel and you can set them to be deadly without killing yourself. My front brake is always one finger, and in racing it has to be that way.
 
everyone want something different and for different reasons, I'm manufacturing 5 different front brakes
for Norton,
Commando 2LS with the stiffening kit
260mm 2LS
260mm 4LS
320mm single disc x 6 piston caliper and slider
320mm twin disc x 6 piston calipers and 2 sliders
the drum brakes are mostly sold to guys building Featherbed based cafe racers, they need the look,
disc brakes for Commandos, looks and effectiveness.
 
easier said than done, the costly part will be manufacturing a suitable cush drive setup, I'm not sure which would be more popular an effective disc brake or a more traditional looking drum brake.
 
As you say, everyone has a different idea of what should be done to Norton brakes, including doing nothing!
My thought on the rear brake is that while the standard disc is not overly powerful, it will lock the wheel if pushed hard.
In emergency braking (a car pulls out from sideroad) I use both brakes and the power of the existing rear brake is good, more brake is not needed. I imagine the standard drum brake on earlier bikes can be tuned up to lock or nearly lock the rear wheel during an emergency stop. That is all the braking one wants on the back.

So I believe you have the right idea in concentrating on the front end, both for practical reasons and the financial side of it.

That front hub could be used the same as the 1970's Ducati 900 SS's which used the same hub front and back with a bolt on cush drive carrier,disc on the other side.

yep good idea.
you realise that to supply the rear disc hub setup, one would have to supply caliper and mounting hardware, mastercylinder and mounting hardware, linkages, hose etc etc, it gets pretty involved, people want goods that bolt straight on out of the box. who out there is gonna pay $800 or $1000 for this complete setup? probably not many.

I left that bit off the post, had to shoot off and put a last second bid in on a Moto Guzzi 850T rear hub (cush rubbers) and twin leading shoe brake for my 73 Eldorado,outbid,thems the 'brakes. :D
 
It was only when i jumped back on the commando from the super blackbird ,did i re-discover rear brakes.. :lol: Good stoppers on the front are a must . Depends if you ride or glide.

Looks great. I see you got the fender.

What is that setup going to run?

I love seeing all this wonderful stuff being developed.
 
thats a reproduction fender of the one u shipped me Brent, I have a local guy making some for me and painting them silver, very nice job.
I just listed this exact setup on Ebay for $1200
