Summary
The Specialized Demo is a downhill bike that excels in gnarly terrain with its supple suspension and planted handling, making it a favorite for steep and technical tracks. However, it faces criticism for its pedaling efficiency and suspension that can feel wallowy or bottom out under hard use. The bike's design, including its asymmetric frame and low bottom bracket, contributes to its confident ride but can also lead to some handling quirks.
Super-supple, traction-rich suspension isolates your feet from the roughest terrain
Low bottom bracket and short chainstays make for a connected, planted feel in steep tech and turns
Asymmetric frame design for easier access to the shock and cool looks
Impeccable finish and true internal routing leaves the bike rattle free
Great geometry and progressive sizing mirrors the more expensive carbon design
Linear suspension can hamper front wheel grip when cornering hard
Pedalling efficiency is compromised
Feet dragging on the insides of ruts due to low bottom bracket
Suspension is easy to bottom out
Basic fork internals and components are lacking compared to competitors
Awesome in gnarly terrain, but a little wallowy when pedalling or cornering hard
A bike that shines on pure downhill
The Specialized Demo 8.1 Alloy looks just as good as its carbon counterpart, but costs 50 per cent less.
Sometimes things just click, as they did on our very first run with the Specialized Demo 8.

Awesome in gnarly terrain, but a little wallowy when pedalling or cornering hard. Buy if you want a bike for the roughest, steepest, most technical tracks around

Low bottom bracket and short chainstays make for a connected, planted feel in steep tech and turns
Linear suspension can hamper front wheel grip when cornering hard, especially on the XL size

2015 downhill bike of they year, 2016 downhill bike of the year, 2017…? The Specialized S-Works Demo 8 is bike we chose to run at the World Championships simply because we couldn’t find a frame that beat it. We’ve now got a National Championships and Worlds podium on the beast that probably prove we were […]

Great geometry and progressive sizing give the Specialized Demo 8 Alloy an edge. Everything about the Demo’s parts package is pretty much bombproof.

Basic fork internals put the brakes on an otherwise rapid package

The Specialized Demo 8 Carbon is worth a look for serious downhill riders and racers

All New Specialized FSR Design with Concentric Bottom Bracket Introduced at Crankworx Whistler, 27.5-inch wheels are infiltrating the DH scene for 2015, including one of the industry’s last holdouts of the ‘tweener wheel size in general - Specialized. In addition to their recent 27.5-inch Enduro model introduction, next year’s Demo will now be available with 27.5” wheels, too.

Specialized's all-new Demo Carbon 650b features a radical asymmetric frame design, 27.5-inch wheels, and a new FSR suspension layout. Plus the low, lean racing machine just looks flat-out fast. - Mtbr.com
