I checked out a couple of the Kona bikes at Dirt Demo…the CoilAir (above) and the One20 (after the break).  The CoilAir is their Enduro / Freeride bike with a unique rear suspension set up.  It uses two separate shocks to give it a solid platform when pedaling, but a softer, longer travel movement when bombing.
The CoilAir comes in three varieties…the regular, the Deluxe (shown) and the Supreme, and they’re available in five sizes from 15″ to 20″.  Both the Deluxe and Supreme use 165mm Fox forks, and the non-adjective version gets a 160mm Marzocchi fork.  All use 20mm dropouts.
We’ve got HD VIDEO of these bikes on a previous post that show the rear suspension in action.  Check out more specs and pics of the CoilAir plus the Scandium One20 trail bike when you read “more“…
Click on the pics to enlarge them.  This shows the secondary “coil” shock that gives the bike an extra inch of travel when you’re not pedaling.  The Air shock above handles the primary six inches of suspension travel…and the combo is what gives this bike it’s name: Coil.  Air.  CoilAir.
Just a reminder, there’s video here that shows how this works.
Here’s the drive-side view.  Kona has a “tech” page dedicated to explaining this set up here.
These bikes are set up to optionally use the D.O.P.E. system for the rear brake.  That’s basically a floating brake system the keeps the caliper in the same position on the disc regardless of suspension movement, which is said to eliminate brake feedback.  If you look back up at the non-drive-side pic, you can see the mounting hole for the D.O.P.E. bar.

Pricing for the CoilAir series starts at $2,399.  The Deluxe is $3,999 and the Supreme is $5,799.  All of the frames are 7005 Aluminum, so the real difference is in the parts spec, which ranges from basic Shimano Deore up to a solid XT/XTR mix with Mavic Crossmax ST wheels.
For the none hucking group, Kona’s got the lighter weight, Scandium One20 full suspension trail bike.  Pictured is the Primo edition…the line up includes One20 regular, Deluxe, Primo and Supreme, all with 120mm travel.
The base model and Deluxe are 7005 Aluminum, and the Primo and Supreme get butted Scandium frames. The Primo, shown, has a RockShox Recon fork, Fox Float RP2 shock and Mavic Crossride wheelset.  It’s largely a Deore build with XT Shadow rear der and some Kona house-brand parts throughout the cockpit.
The big downtube curves into the bottom bracket with a pretty sizeable contact patch, which should help keep the BB area stiff under power.
A one-piece rocker arm keeps the top side of the suspension stiff.  The One20 is available in a massive range of seven frame sizes, from 14″ up to 22″.
Pricing isn’t shown on their website for these models yet. Full specs are available at Konaworld.com.
