YSS started out in 1983 making good quality budget shocks, - we sold loads of them. Then around 2001 the company moved upmarket. They partnered with leading European shock designers to produce a stunning range of shocks to fit most bikes in the park, from old hack to full race bike. They now make more than 2 million units annually, all ABE/TUV approved and all with a full 2-year warranty. Built with the latest CNC technology, YSS shocks look and feel real quality pieces, and the lower manufacturing costs from building the shocks in Thailand mean that they are seriously good value.

Shown here are the RE302, RZ362, and RG362 ranges, which all have threaded preload adjustment, all mount rod-down to reduce unsprung weight, and all are rebuildable. RZ366 and RG366 models, which have heavier duty 16mm rods, are recommended for some applications.

Also shown is the RT306 triple piston shock for Harley Softails. These shocks work in a way totally different from most shocks: increasing the load on the shocks, or weight on the bike, makes the shocks longer.....weird, unless you're a Softail owner!

Koni stopped making bike shocks years ago, but all the designs etc were transferred to IKON, who have carried on making exactly the same shocks, still the chrome damper/black spring 7610 series and all the same applications plus of course lots of new ones. The 7610's still have hydraulic twin-tube chrome dampers to give a smooth ride, 3-position preload adjustment and 4-position dial a ride damping adjustment. If you are one of the thousands of riders who liked the old Konis, you'll be happy with a pair of Ikons.

Burly are very well known in the US, not so much in the UK. They concentrate on custom parts for Harleys, with ranges of handlebars and sissy bars plus foot pegs and cable kits, but they're best known for their slammer suspension ranges, designed to lower your Harley as much as possible without turning it into a hard tail. We sell the slammer shocks separately, but you can also buy complete slammer kits (lowering fork springs plus short shocks) - see details in our front suspension pages.

The slammer shocks, known as stubbies measure 10.5 inches between mountings, which is as short as you can go and still have a little travel available. Progressive, who make a great range of shocks for all Harleys, won't go that short....their shortest shocks are 11 inch.

And just to be different, Burly also make a range of shocks to jack up your standard ride, called Stilettos. Burly have designed their Stiletto range using twin springs, which results in a very progressive performance. Small bumps are dealt with smoothly by the lighter duty red spring, while bigger thumps close up the red spring completely and allow the harder main spring to take control and keep the bike stable.

Progressive have become the largest US manufacturer of aftermarket bike shocks since they started out more than 30 years ago. They concentrate their applications lists on more popular bikes, mainly twinshocks, and test all their products thoroughly to ensure a good match between shocks and machine.

Each range of shocks come in various lengths, mainly 11/11.5/12/12.5/13/13.5-inch (280/292/305/318/330/343mm), and with standard or heavy duty options depending on the weight the bike will carry. Standard shocks will suit riders who weigh up to around 16st (100kg) and carry an occasional pillion. Heavier riders or those who mainly ride 2-up will gain a more controlled ride, with less chance of bottoming out, with heavy duty shocks.

Not a name that too many people have heard of yet, but surprisingly good value, 2WIN twinshocks are built at Mike Capon's Shock Factory in France.

2WIN shocks have both adjustable damping and continuously variable preload adjustment. The single damping adjuster covers a wide range of options, controlling both compression and rebound with 14 clicks of adjustment. With each extra click both compression and rebound are increased keeping the same preset ratio to give great control over the hardness or softness of your ride.

All the shocks are built to order, with springs and damping rates chosen to suit rider/passenger/luggage weight and riding style.

Construction is mainly CNC-machined aluminium so very lightweight, and anodised in clear and black for good looks that last. The springs are hardened and tempered then shot blasted and finished in a tough, long lasting epoxy polyester powder coat.

They come with a 2-year warranty and are rebuildable.

The range of applications is growing all the time, and many popular tourers and cruisers are covered. We can also get upgraded shocks for sidecar outfits, and special build shocks, normally all at the standard price.

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 60mm diameter top cover and a ribbed 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. Either of two small hand pumps (HP30 or HP40) provide up to 30 bar (430psi) or 40 bar (570psi) and can easily be carried on the bike.(see pic).

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!

Hitting the 'BUY' button transfers you to our sister website where you can find your application and purchase online.

You can also get all the benefits of Fournales high pressure air shocks if you own a Harley Softail. Available for all Softails, both early and later models, these shocks have two separate air valves, allowing separate ride height and effective spring rate adjustments.

German company Wilbers are one of the largest shock manufacturers in the world despite making only very high quality (and therefore not cheap) shocks. They are also one of the few manufacturers who extend their warranty beyond 2 years - Wilbers shocks are warranted for 5 years, although you need to have them serviced after 2 years to activate the extended period.

The Wilbers twinshock range is quite varied, but for roadgoing sports bikes it mainly comprises the four models shown here. The 530 series is the basic range, with adjustable preload. Next comes the 630 series, which adds 22 clicks of rebound damping adjustment to the 530 spec. Then there’s the 632 series which are piggyback shocks and add compression damping adjustability. Plus for track day use we’d recommend the 633 series, which allow separate high-speed and low-speed compression damping adjustment

Although not shown separately here, Wilbers have developed a range of shocks specifically designed to replace the electrically-adjusted shocks fitted to recent generations of BMW, and customer feedback on these shocks has been very positive.

All shocks have true variable rated springs rather than simple progressives, which helps to optimise performance under variable road conditions. And uniquely you can specify the spring colour. Standard options are Blue Line, which have blue springs and red/blue coloured adjusters or Black Line which have black springs and silver adjusters. But for an extra charge you can select almost any colour, and there’s a handy page on Wilber’s website which shows how the many available colour options will look. See it at http://www.wilbers.de/ral.php.

Wilbers build their shocks to order in Germany, to suit rider weight and riding style, and all are of course fully rebuildable. Expect around 3 weeks from the day the of order to delivery.
