There can be a number of reasons for replacing motorcycle rear shocks. With other makes, the bottom mount can run into the frame. More rear end grip Once wheels are bouncing, the tires would ge tout of round pretty quickly causing even more bouncing, road noise, grip issues. Brakes take more time to stop the car In addition to nose diving when applying the brakes, it takes extra time for the vehicle to take up all the piston rod length if uncontrolled and this adds time and extends the stopping distance required to come to a complete stop. They are held in place by a set of triple trees that turn at the steering neck. With the bolts gone, you can now remove the top bolt.
But in most cases simple removing the rear wheel to get at the linkages will suffice. With the rebuilt shocks installed the ride was primo again. Make sure all torquing is done according to factory specifications. If working with dual shocks, it's essential that damping on both shocks is the same. When we see the rear shock absorbers of any two wheelers, they are majorly categorized into two- Mono Shock and Dual Shock absorbers.
Know which kind you have, what you need and how you need to get it done, so that you don't find yourself halfway through the project and realizing that something is not adding up correctly. Matt says anything from a 5wt to 30wt fork oil can be used to control spring action via rebound damping. We replaced the seal head and the piston band on the main and dividing pistons. When shocks and struts go bad, they must be replaced as they negatively affect the handling of your car and can increase braking distances. And without a bushing carrying the load the sliders work directly against the tubes, shedding aluminum into the fork oil as they move up and down the hard chrome fork tubes. Spring preload—or the amount of force applied by the internal spring before compression—was set by installing a spacer at one end of the spring. Every issue delivers exciting and evocative articles and photographs of the most brilliant, unusual and popular motorcycles ever made! Rebound damping is controlled by fork oil viscosity — the thicker the oil the slower the rebound, the thinner the oil the faster the rebound.
Before we go ahead with the details of the topic it is mandatory to check how a shock absorber conventional works- A regular spring loaded damper normally has: 1 Spring 2 Body or Tubes 3 Piston 4 Valves and 5 Damping Oil. Our extensive experience and machine shop facilities enable us to carry out servicing, repair and modifications to all of the many and varied types of shock absorbers seen on most motorcycles today. They can also be bought with ride-height adjustment so the steering characteristics of a bike can be changed. The rod assembly is fitted to the shock body, the shock is re-oiled, bled air free and then connected to the assembled reservoir and pressurised. The custom springs fit me perfectly, no shaking, no bottoming, and 25 to 30 mph higher speeds on the same piece of road.
You must be wondering what these dampers are and how good they are as compare to the regular spring loaded shock absorbers? Removal Some parts on a motorcycle will be difficult to get off, but others can come off remarkably easy. Tighten and Adjusting When putting bolts and other various fasteners back on your motorcycle, it is important to always be confident that they are attached as tightly as possible so that they do not come loose or even fall off later on. On some bikes, there are rear and forward linkage bolts. This leaves the inside smooth and slick, while the outside takes on a matte black finish. Top brands like and are using potentiometers, accelerometers, and electronic control units to actively change the damping adjusters. Experiment a little to achieve the optimum working height for removing the motorcycle rear shock. You should clean the area of the motorcycle that you are working with free of any dirt, debris or oil before you begin your work.
Try it at the halfway point for starters. It lost the majority of the nitrogen and oil, and the main reason the seal failed was probably because the recommended service interval had not been followed. We used Spectro brand 15wt fork oil, which Matt recommends for vintage applications like the Laverda. Before fitting the new shock, by using info from the supplier, set the damping adjusters and spring pre-load to a recommended base setting — it saves skinning knuckles if you hold the shock tightly in a vice. The updates we did completely transformed the Laverda. If the new shock requires that you use old bolts or bushes, give them a check for corrosion and clean them up with wet and dry fine grit paper.
To this day, many bikes are still made with either arrangement but are far from practical in the world of competitive racing. As above, we always recommended having your shocks serviced together. Leaking fluid Sometimes the seals surrounding the shaft extending from the body of the shock will begin to leak and this will run down the side of the shock towards the ground. Uneven tire wear A worn shock is unable to keep the tire firmly on the road surface. Due to the tolerances of machining, it's impossible to sync two shocks perfectly, no matter how skilled the tuner is. The Laverda has 38mm Marzocchi damping rod-style forks typical of the 1970s and 1980s.
Everything To Rebuild Your Rear Shock Here! Skip the repair shop, our top-rated mechanics come to you. The other end At the back, we swapped the tired set of Konis for Race Tech G3-S shocks. These same people, however, follow the recommended service intervals on their engines and generally do not question it needing parts. Through the next few championships, most racing teams chose to iron out the creases of telescoping forks rather than doing so with other inferior alternatives. Before the 1970's, most motorcycles incorporated two shock absorbers on opposing sides of the wheel until the benefits of a monoshock swingarm came to fruitio.
