Fournales air shocks have been around for more than 30 years. They started out with competition-winning trials shocks and
developed hundreds of applications over a few years. Made to order in France, they have a dedicated following among
riders who appreciate their excellent performance, long life, ease of adjustment, light weight, and most of all the quality of ride they provide.
These days Fournales also make suspension units for light aircraft, and the bike shocks benefit from this high-tech knowhow.
They are high-pressure air shocks, with the air acting as a very progressive spring, with hydraulic damping tuned specially for
each bike model. The internal air pressure can be adjusted (in effect to provide your perfect spring rate) and once set up these
shocks will not bottom out - they simply get harder as they are compressed. As a result both traction and performance under braking
are improved, and the superb ride quality is ideal if you or your passenger suffer from back pain.
The twinshock range comprises four designs of rear shock (excluding Harley softails), with a wide list of applications - although
Fournales seem most popular with Guzzi, Triumph and Harley owners.
The Air Twins and Classics are both slimline shocks, with 50mm lower body diameters. Air Twins are finished in black steel top covers
over chrome sliders, and have an exposed schrader air valve at the top. The Classics have the same internals, but have a chrome top
cover which conceals and protects the schrader valve. (To adjust the pressure, the top cover unscrews and drops down to expose the valve).
Magnums have a chunkier look to them, and are popular on larger bikes and cruisers. They are all chrome with a smooth top cover
and a ribbed 60mm diameter lower cover. Like the Classic shocks, the Magnum air valves are accessed by unscrewing and dropping down the
top cover. The Black Alloy range were originally launched with Harleys in mind, but they have proved very popular with owners of
many other makes and Fournales have greatly expanded the list of applications. Similar in size to Magnums, but finished in black with
anodised aluminium hoops. All Fournales shocks are light in comparison with traditional coil-sprung units, but these Black Alloys are super light!
Fournales shocks are very long-lived and fully rebuildable if/when they eventually need refurbishing. They are supplied fully pressurised
and ready to fit. Many riders find that the standard pressure suits them and do not need to change it. But if, for example, you plan a
long distance 2-up holiday it makes sense to increase the pressure to convert the shocks into heavy duty units for the trip. A small
hand pump (the HP30) provides up to 30 bar (430psi)and costs £52.50 or £45 if purchased with shocks.
All Fournales twinshocks can be uprated for fitting to motorcycles with sidecars. This should be specified at time of order. The shocks will be
built to match the additional weight, and in addition will run at an air pressure approx 30% higher than for the corresponding solo machine.
Although not cheap to buy, they can end up being much cheaper than inferior shocks because of the great mileages they can cover
without significant loss of performance.
As these shocks are all made to order in France, delivery takes approx 3 weeks, except in the summertime when, being French, the factory
closes for the whole of august!
