featherbed frame

Please,
I would like to learn the differences from wideline and slimline and how i can recognize the differences.
I would be happy to see posted ome pictures.
Whoch engine is possible to fit into the frame?
Maybe a Trident engine?
Thanks.
Piero

Top frame tubes on a Slimline taper inward slightly at the rear, Wideline tubes remain parallel from front to rear.

Also; at the bike looking from sideways on, on a standard unmodified, repeat unmodified wideline frame it has a bolt on rear sub/seat frame. The tubes at an angle are straight from the frame to the top of the rear suspension mounts whereas the slimline frame are welded onto the mainframe and are curved to the rear suspension mounts

this widline is welded rear sub frame;

Stick your nose in here wideline-featherbed-frame-tube-t13951.html theres those annoying pictures there :wink: .

Hi thank you. Atlas frame is a featherbed? In case is a sl or wide line?
Ciso.

60 on the slimlines Shock Mounts is ONE Bent Tube ( V with round end ) i.d.s ' Slimline ' , the whole thing is ' retooled ' , Atlas is 61 on - So Slimline .

Diehards prefer Wideline , but theres several , pre 54 bolt on rear subframe . post welded on . Manx seat frames angled down at front . dates Approx .

The Lowline was the works Twin ' raceing department ' effort , passed on to Dunstall .

Frames for Singles are alledgedly bigger than twins , at least in Widelines .

heres the grotty wideline Seat & Tank .

and the grotty SLIMLINE ES2 .

See the rear frames not at all the same , or the Seat of Tank . for the Road Models . No Comp Slimline , Bar Prod Raceing :? .

This is aledgedly a 1962 ATLAS with the shallow export thingo tank .

Heres a 60' ' 88 ' .and a fine machine it is , too .

( looking for a S/L Inter pic :x )

Now , you might have Noticed , Its a ' Dual Loop ' frame - a Parralelograme , almost ; semi Rectangular even ,

Getting really Awkward . Seeing YOU mentioned R III s , THIS is a ' DUAL LOOP ' Triangle'o'grame ( )



and SEE that Hairy sucker sitting in there in it . :wink: so If You want to wear the ends of the footrests off ,
it might be the way to go .

There ARE a few of these that arnt a toatal disaster ;

But the issue is to not only Please yourself . But to Not Kill Yourself . some are a trifle haphazzardly contrived .



So the advice would be to KEEP IT BASIC , IF You Must ( do it . ) The fancy parts are better spent on a ' Works Rep ' .
if you own a few banks or shipping companies . A Dirt Track triple is a Ligit Device , lesser tyres will let you slide it around
without overstressing the frame . Id ONLY use a near perfect std original paint production norton fame ( if you must ) So It Doesnt
fall apart , at the most inconveniant oppertunity . And You Be Better putting a NORTON Twin in it , ANYWAY .

The Trple has TWICE the Parts Count of the olde Commandoe . At your peril . And Not a iota amiss with any , if you dont want trouble .
Not to put you off - but be aware of what youre in for . And TRIUMPH didnt make too bad a job of the things in the First Place ,

despite this pack of beer swilling retards


the Govt , the unions , the banks , and industrial espionage & cheapskate opertunists & one or two other things .

So a mint classic wideline commando manx mightnt be a bad idea . Outside of that , dont change anything . Unless itll go FASTER . :twisted:



some idgit paid 1,275.00 pounds fore This

itd likely go in there . A A65 will .

if you can find a frame , if they didnt all end up in the scrap . Some looney wanted 35.000 for a bike recenrtly ,
SOMEONE must own a bank or two , the odd oil well . Or Goldmine . :?

What engine is possible to fit into the slim line frame?
Maybe is possible to mount a Trident/Rocket 3 engine?
Piero

ER , Yuk. He hasnt got a clue. JUST LOOK AT THOSE PIPES ! . the Headlight Mounts . No sense of proportion . or much else at all . ( fumeing Icon . )

:wink: :roll: :mrgreen:



you might think 80 horses wouldnt mind a few right angled bends , but its UNLIKELY .
And SEE the THROTTLE Doesnt Stick . :shock: ( 6 : 40 )

Don't mislead him. Most Wideline frames left the factory with welded-on rear subframe.

Slimline




Wideline


Putting a Norton engine in is easy. Putting a Triumph twin engine in is easy-ish.

Putting a Trident engine in is not easy.

Piero, for a Trident or Rocket 3 motor, you need a Rob North frame or a Hyde Harrier. I don't believe you would get the weight distribution correct using a featherbed. A standard Meriden triple is likely to stand up under power, and a featherbed with the motor too far back would be worse. I would not attempt to race tune one of those motors, a nice near standard onewith a decent pipe, which really handles well might be a good thing though - for a bit of fun.

The bends in the vertical tubes don't look like the work of a tractor.

I just about had one bent by a Milk Tanker once .*
' IT ' Was on my shoulder whilst pillion . Pilot farmer Brown mustve been day dreaming , not to mention the tanker driver ,
Altered my grip least it change trajectory . there was at least 18 inches between the tarmac at the large terminal post .
With the Tanker Artic & trailer on our side of the bend . mustve been .005 secs ahead , so we squeezed through aft .
Maybe .
Though I was narrower twisted sideways thereabouts . :shock: :wink:

The driver'd slowed up, up the r h sideroad , and his looks aft were under the tanker wheels initially , Seemed to brighten up
when he looked back down the road .

Never relax near home . Browns Road was the Next Left . . :wink: :| :shock:

' Tractor ' ? just a note of levity , young man . Not to quick on the uptake these young fellers . seemed appropriate to the Background . :wink: " :lol: "

* was back in the clueless youth days . bin wondrin wot model awhile . Just Recalled it went to old John out at the highway , with the 500 T & 88 . He'd been spat of a Commando on a ' S ' bend
at the top of the Waiwera hill heading south , though I think he was heading north . He parted with it . a 1969 / 70 model .

A featherbed frame fitted with a manx engine makes a very nice bike. It might be nice to theorise that fitting a stronger motor into a frame which was the best handling in the fifties would give the best of both worlds. However it does not work like that. I cannot think of a worse bike to race than a Norvin. Even tritons feel really big when you race them. The average Z900 Kawasaki feels like a British 350 to me. Rob North triples are very nice competitive bikes, a good guy on one would give my Seeley commando a very hard time. There are a few of them here in Australia, however they are rarely raced. The best of them had a $24,000 motor, and was extremely fast - you'd need a very big bank balance.

Bah . Cobblers .

#87, the Corish Vincent in 1964 Keith Corish saw Arthur Pimm's Vincent- engined Norton at Bathurst and was so impressed that he decided to build a similar machine. Combining the power of the Vincent and the road handling attributes of the Norton Corish created the Norvin!He used a Norton international frame, a Norton Manx close ratio gearbox, Manx rear wheels and two eight inch Bsa gold star hubs back to back to build what was to become one of the most successful and well known bikes in Australia's motorcycle racing history, no. 87, the Corish Vincent.Corish asked Eric Debenham to race the bike and together they made various improvements including replacing the clutch with an Amc bonded steel unit and a 2LS Manx front wheel and 2LS Ajs 7 rear wheel in 1965.the bike was very quick but stopping it was a problem so in 1967 a double disc brake set up using Dunstall units on the front wheel was added in 1969, after coming off in the 1968 event, Eric Debenham again rode the bike at Bathurst regularly timed at 165mph and seemingly breaking the lap record at will time and time again

Enough Balls :wink: .

I am fairly certain that the Corish Vincent was owned by Eric Debenham in the 60s. However there seems to be two of them, besides the Pimm Vincent. Also I don't know where Ken Lucas's Norvin came from. The Arthur Pimm Vincent was ridden by Bill Pound - Trevor's brother, in about 1968 at Phillip Island, and it was later owned by a guy in Geelong . The Debenham Vincent was raced successfully against the TD1Cs at Bathurst in about 1963 - Eric must have been a baby. I spoke to him at the old farts meeting Mount Gambier in 2003, and he seemed about 5 years younger than myself. In 1963, I was about 21 years old. He was an excellent rider, I saw him lose the front end, catch it again, and went straight back on line without hesitation, riding that big brick.
The restored Corish Norvin was sold about two years ago and I think it went O/S. I don't think it was the bike with the history.
You'd need any of them like a hole in the head. I saw Arthur Pimm win a lot of races against 500cc Manxes - fast in a straight line however the sort of thing that would give you nightmares . I've crashed too many times. The Irving Vincent is far superior.
