Rigid vs Duo-Glide

...I'm plotting my next project and can't think of a better group to ask.

I've been riding rigids for a long time and want to build something more comfortable for longer trips. I always wanted to build a big inch flatty and was thinking about a Duo-Glide frame (solo, foot shift). Does anyone care to comment on the comfort factor and handling, rigid vs Duo? Thanks.

JMHO, but I don't think a rigid frame rides that bad if everything is set up right.
Correct tire pressure, good padded, sprung seat, preferably a wide glide fork since they ride much better than a springer, and it's a wash to me anyway. Personally, I can live without the shocks.

44u, a rigid with a glide front was my initial thought. I'm currently riding a rigid/springer/4" tire which is hard on the kidneys after a few hours. I did spend some time on a 48 pan/glide/5" recently and it was much better.

A strictly personal thing, but I never liked the look of the back end on the swingarm frames. But because it's going to be a bitsa bike, I could probably put on a rigid fender with struts etc. (moves with the swingarm) and get the older look that I like. The cost and availability of a good frame is a bonus. I'm still curious to know if the shocks add much. Thanks for the comments.

JA, yes the shocks add much...weight!
But that you knew already, Imho I think it's the passenger who benefits most from the rear suspension...when I listen to the OL after some miles.
I must admit that I go for the suspension on longer rides also...age?

Stéph, ...for me, age and an expanding girth.

And no passenger issues as the OL will not ride with me (lingering reputation from a renegatus youth).

Get a rigid frame, a stock solo cop seat, and a good seat post with new springs and lots of grease.

I spent an hour yesterday on a close to stock 61 Duo and it was an eye opener! The ride comfort was OK, and the rear brake was great - it had the later/wider drum assembly. The tires and mechanical bits were in good condition and I didn't feel any low-speed wobble. I suspect because of a hydraulic aftermarket steering damper set on firm.

Going around corners, the handling was as bad as on anything I have ever driven. I know it's first generation but you'd think they would at least looked at a featherbed Norton. I almost want to get one to see how much it could be improved (...now that's irrational thinking).

I suspect bad dampers, lousy spring rates and a whole lot of flexing goin' on. Has anyone tried to improve things?

As a starting point maybe a fork brace, progressive springs and new damper valving. In the rear; new inserts and progressive springs. The swing arm looks like it could use major bracing around the pivot point and some bracing on the arm itself. I know it will never be a GP bike, but it could be waaay better than it is.

I made a duo glide handle pretty good back in the day. Tossed the H-D fork and put on a dual disc water buffalo fork with brace. Braced the swingarm and used aftermarket shocks (progressive I think). Single disc rear, morris mag wheels 19" front 16" rear with the stickiest pirelli tires I could find. 84" pan/shovel with Branch heads etc. Mid mount fold up pegs. Handled the power just fine. Today I would use a late model inverted fork assembly and the matching aluminum swingarm from a donor crotch rocket. I'd also consider an FXR type frame as the foundation. There's a guy in NY state that builds like this; his last name is TODD. The rigid would be easier and fast. To save your back you could put a seat post shock absorber into it and run a K solo and pill. 'dog

Looks like I was a guest on the BG statement.
I'm a tech by trade and pretty cynical by nature. A BG rep came in the shop once and I had a chance to personally go through a demonstration with their oil additive.
Essentially, it was a 110volt A/C motor with provisions for mounting a torque wrench and loading the motor shaft until the motor stalled - basically, steel on steel.
With a dry shaft the motor would stall at about 10-15 foot pounds.
With one drop of regular engine oil, it would stall at about 30 or so.
With a drop of BG I had to apply near a 100 foot pounds to slow it down.
There was no way I could see this being rigged somehow and after being given several samples I figured the old clunky HD would be a good guinea pig.

About 2 ounces of BG added to each fork leg and a full can to the trans. It definitely helped the ride quality and smoothed the trans out. I gave a couple of cans to a bud of mine to get another opinion and he stated that it made a noticeable difference on his 84 Softtail.
This stuff is actually engine oil treatment but I figured what the heck. It was free and worth a try.

It's clear after spending an hour on one and listening to your comments that a Duo is not for me. I'll go with a rigid and an air shock. I have a bladder from a police seat that should work.

It's going to be a frequent rider and I want it to be dead reliable, handle well and stop. I can't quite bring myself to use disc's so I'll use a 4 shoe racing front drum with street linings, (...been saving a Grimeca for something). Front forks will be modern; maybe 50mm Marzocchi - they're big and look sorta like a Glide. Raised, narrow footboards and a tucked in exhaust as suggested.

I'm going to keep everything else as vintage and stock looking as possible, plus it will be a mildly stroked U.

Many thanks to all who have replied.

-Jim

...hoping the air bladder will reduce the pucker factor, maybe even a gel insert in the seat - damn I'm getting old.

JA, I don't think the air bladder alone will be enough, not that much travel. Always felt the best ride (on a rigid) is the original pogo, but its gotta be set up correctly for the individual, correct springs, good slider/bushing fitment, and keep it greased..
