Nope, just ignorant but I'm trying to fix that! 😬😬

 

OK, but an 883 is a Sportster, not a Dyna. It is expressed in CC's and the 74,80,96,103,110 etc are in cubic inches.

 

Yeah, I probably should have said that I have a sportster. I'm just curious about the different dyna models. So between the sportster and dyna families the engines are numbered differently?

 

Not all low riders have dual disc brakes...

 

With Dynas the numbers are Always a reference to engine capacity 96 cubic inch 103ci 110ci etc etc

All modern sports are either 883cubic centimetre or 1200cc

The names in the sporty models 48, 72 etc are not engine related.

Its all part of the MOCOs master plan to confuse new riders

Mission accomplished.

Spend some time in the pic sections of this forum and also the link cvaria posted and edjamakate yourself some more.

 

Yes. Sportster engines are designated in metric: Cubic Centimeters, CC's. Big Twins are measured in imperial/SAE: Cubic Inches, CI's. An older Big Twin of 88ci is 1450cc. A 103ci is 1688cc. A 110cu is 1803cc.

Differences between Dyna models vary depending on the years you're considering. Can you narrow it down a bit?

Stock Big Twin transmissions are left side drive (belt/chain on left).

There two different Big Twin Twin Cam designs. One is the "A" designation which all Dynas have. The other is the "B" designation which is counterbalanced for smoother operation and comes in the Softail models. They are not interchangeable.

All stock Dynas have twin shock rear swingarms and front hydraulic/oil damped telescoping tubular forks. Just like Sportsters only beefier...in most cases.

All stock Dynas have three engine mounts: top, front, & rear. Top is a heim jointed link. Front and rear are rubber isolated. Many people upgrade one or all, particularly front and rear, and/or add heim jointed lateral stabilizer links. The rubber isolators can allow some rear tire/swingarm wiggle that adversely affects handling.

Within a given model year:
Fuel tank capacity can vary slightly.
Rake varies.
Instrumentation/ignition switch configuration varies.
Front brake count (1 or 2) varies.
Front tire size varies significantly.
Wheelbase and seat height varies.

 

Thank you!!! That cleared so much up!

 

Another really helpful post! Thank you, it's only day one and this forum is answering so many questions

 

The biggest differences will be noticed between Fat Bob, Wide Glide, and Street Bob

Line them up side by side and the differences should be obvious. Mostly from the tank forward.

With a little effort (and money), you can generally swap parts back and forth to create a nearly limitless mix.

For example, I'm putting a 2009 Fat Bob front end on a 1999 Wide Glide. More rake, more brake.

 

Here I fixed it...
For example, I'm putting Fat Bob Tube/Slider Assys with "Wide Glide" Triple Trees on a 1999 Wide Glide. More rake, more brake.

Just doing my part
