Some sliders, usually aluminum ones, mount integrally. Others have mounts secured by fasteners, like washers, nuts, and bolts. Press-fit items may fare better in a bending scenario and help keep some forces from being transferred to the frame, but they may also tear away just when you need them most.
Anthony equipped his Ducati with frame sliders. He's a sucker for the moto-sexy, so carbon fiber and aluminum covers were put into play. By and large, sliders are made of some form of aluminum or plastic, or possibly both. Aluminum sliders will typically wear down more slowly over a given distance than plastic, but the coefficient of friction is higher, so it may be more apt to flip the bike over.
Plastic sliders typically glide over the surface better, but they wear down faster. Plastic-based sliders also are far more susceptible to melting, depending on what polymer is used. Sliders that utilize both materials attempt to marry the best features of each, but harbor a potential weakness at the joint where the two materials meet.
Axle block sliders are a fresh take on crash protection. Rather than relying on a small tab welded to the swingarm, they use the axle to help distribute crash loads, utilizing more of the swingarm's supported area for the task. Axle sliders can be installed on the front fork, and their counterpart, swingarm sliders, can be installed for some rear peace of mind. Axle block sliders are a derivative of the swingarm style and integrate the rear axle into the overall protection plan.
The axle and swingarm types of slider are also available as spool sliders, providing even more function. Spools are small items shaped like their namesakes that serve as lifting points for paddock stands.
Keep in mind there are other types of protection, like case guards, if you want to protect more than just your chassis. Counterintuitively, hardware made of mild steel often performs well to fasten sliders, due to its propensity to yield when force is applied. Common hardware grades in the United States are grades 2, 5, and 8, with strength increasing with number. Bolts are made stronger through the amount of carbon in the alloy, as well as the specific heat treatment of the fastener. Bolt hardness is gained at the expense of flexibility.
A strong bolt is also usually fairly brittle. Lower grades of hardware may deform or break, failing to protect the bike. There are no right or wrong answers when it comes to protecting your bike. However, understanding the range of materials and designs that exist will aid in the selection of a part that will be best tailored to an individual riding style. Navigation Menu. A common misconception is that a frame slider will protect the bike from ANY damage when dropped.
A frame slider should stick out just enough to protect the main frame and possibly the engine, any further, and the slider becomes obtrusive. Frame protection is vital in keeping your bike rideable home, and to keep your bike from being totalled out due to frame damage. Designed to fit into the front axle opening of your forks, Fork Sliders are an important piece of the protection package.
With motorcycle forks today being high tech and adjustable, the cost of replacement forks is extremely high. With the added chance of scratching a wheel during a drop, the fork slider is an unsung hero. Typically an easy part to install, a good set of fork sliders is peace of mind that your bike deserves.
Basically if the bike tips over, you dont want the fork lower or the wheel lip to be able to contact the ground. Very similar to fork sliders, the rear axle sliders are designed to offer protection to the rear axle area of the bike. Swingarm, Wheel, etc. While its true, that in an exhaust side crash, it is most likely going to be the exhaust that keeps the rear wheel off the ground, a rear axle slider can add valuable protection to the bike.
Especially for bikes that have high mount exhausts. If you are going to protect the frame and forks, the rear axle, brake rotor and swingarm need protection as well. Minor damage to a swingarm could cost you your entire bike. Aren't those just for looks? Well, take your bike out and drop it in the parking lot But when you tip one way or the other, that downward pull becomes much more important than your forward motion, and you fall down.
That can hurt your body, which is why we wear our pads and helmets , but if you think about how momentum works, you can see that the force acting on your motorcycle is even more intense: Your mass is nothing compared to the bike's, so your momentum is that much less. It's the action of these two vectors -- the friction between your momentum and gravity -- that grinds your bike against the road, until the forward motion finally comes to a stop.
The vectors are using the physical material of your bike to work out a simple physics problem about which one of them will win.
The slower you're going when this happens, the less damage will be done, because the vectors will equal themselves out more quickly. Likewise, the longer the process takes, the safer your bike will be. Imagine dropping a dinner glass onto the ground, versus skipping it down your driveway.
Those bounces represent sudden sharp adjustments to this vector ratio, and while they're dangerous, they certainly don't create as much friction -- or as much downward force -- as simply dropping the glass. But if you imagine rolling or sliding the glass, you can easily see how the danger is comparatively minimal. What a frame slider does is help prolong the process this same way, through destroying the puck and absorbing the force as designed, but also by lubricating your bike's contact with the road and distributing the force of impact outward to the rest of the frame.
In all cases, the physics remain the same: Your frame slider is lessening the friction between the two vectors and keeping the sensitive mechanics inside your engine from being ground against the road. Sign up for our Newsletter! Mobile Newsletter banner close.
