widleine - slimline, what's the difference?

Hi
Just joined and hoping one of you petrol heads can help me out. I have a Norton Dominator 88 in cafe racer trim. When I bought it I was told it was a slimline featherbed frame but a local "expert" tells me it's actually a wideline...how can you tell the difference?
Cheers
Mel

as far as i'm aware it's something to do with the distance between the upper frame rails. arguments for both, but the slimline seams to be the popular choise among Triton builders.

Thanks guys,
I guess the local "expert" is not as expert as he assumes, the frame is definitely a slimline.

The seat support tubes are the most obvious clue, they are straight on a wideline and rounded[where the shock mount is]
on the slimline.
Funny someone should say slimlines are more popular, I always thought it was the other way round.

Every one I knew in the 60's reconed the wide line was a better road holdiong machine, and that the slimline came into being for comfort of te rider only.

Yeah, I always understood that a Wideline frame with a pre-unit Trumpet donk was the most desirable combination, but probably not much in it really.
Some riders have said that the Triumph OIF handles better than either Notrun frame, but such anarchic heresy is to be suppressed... :26

Easy to tell from looking as tubes narrow in on slimline, but frame numbers are ...

They really are like riding on rails,i had a slimline frame with 6T, but nothing wrong with handling of OIF but then i don't know any different last 20 years ..

(apart from cubbie, and it handles surprisingly well for a wee bike)
