Frame sliders, yay or nay?

    Ive heard that frame sliders can 'pole vault' your bike in a higher speed crash. They also save a lot of damage on low speed crashes as well. Whats everyone's opinion on running frame sliders? Are they worth using, or are they potentially bad in crashes?

    Go with under the fairing style. They protect more and won’t snag a curb, etc and flip the bike.


    Ride safe,

    If you want to run them, they are the besterest.
    If you don't, they destroy Japanese cities and fight Mothra.

    and what's the deal with Mothra? A giant moth kaiju? That's stupider than 12 o'clock bars and ewoks.

    I've had 2 crashes in the past 15 years or so, one on my 1000 on the street at low speed, back end stepped out on me pulling away from an intersection when I gave it a bit too much stick on cold tires. The other coming into T1 @ NJMP on my 600 when the front seemingly washed out under me under braking.

    In both cases the bikes had frame sliders (the kind that do jut out past the bodywork)....in both cases the sliders saved the bike significantly. I know every crash is different but in my case they proved to be VERY helpful.

    Steeltoe What's my move?

    Most bikes in the FIM World Endurance paddock have them. It's more important for them to keep the bike going after a tip off.

    Anything can cause the bike the flip, sliders or not. Happens all the time without them as with them. But sliders absolutely can save controls from being destroyed.

    I bet Tommy Hill wishes his R1 had them when it tipped over on the grid and snapped the rearset mount. Cost him the championship.

    There are a couple situations I wouldn't want 'em...
    - Don't send the bike over a curb when it's on its side.
    - They can act as a lever in the dirt, tilting the bike which, I guess, drives other various bits of bike into the ground. Eventually, something digs in.
    Damage potential is a speed-induced exponential.
    Also, I don't see a need for what, imo, amounts to something that can cause more damage than would otherwise be suffered anyway. Not saying they don't serve a purpose, but I'd rather not mount a four inch lever that has the potential to launch a 400# machine into orbit.

    High-sided exiting Barber's backstraight dogleg in the wet, 110-ish(?), no sliders, bike stayed on the track. Looked like someone took a belt sander and ate through three body pieces and almost through the tank, minimal damage to a clip-on, clutch lever and leftside peg. The rearset mount tabs took a slight bend, 5-10º, Duc 996.
    Still ridable, the hit to my ass kept me off it the rest of that weekend...like getting spanked by a 2x4 that instantaneously accelerates ya 20' in front of your bike. :D

    Low-sided entering BeaverRun T1, GSX-R, sliders, bike slid over the outside curb. Curb initiated ballerina mode...complete wipe-out of all controls, body pieces, tank, wheels, subframe. I rate it a solid 9. :D Unbelievably, I don't recall the pipe getting whacked.
    As the bike was going down I was like "What?! I'm crashing!?" I considered holding on to it cuz it just sorta laid down. (I mighta been able to prevent what, at the time, I didn't know was about to happen.) But, I saw the curb and thought, eh, maybe I don't hold on to this...

    It's hard to say what would have happened if the bikes switched roles or had, or didn't have, sliders.

    In Your Corner It's a little-known fact...

    Sliders or not, a sliding bike that hits a curb or berm is very likely to tumble.

    Handlebars and tires can cause a bike to flip if they snag something...so be careful if you ride with them. :D

    Hopefully enough speed is scrubbed off before the bike is near anything that will help it tumble.

    Just keep it on 2 wheels and you don't have to worry about it. :beer:

    Sliders have saved my tank from bigger damage multiple times. They may also have contributed to some frame tweaks from some low sides that slid over a curb. I run them just long enough to protect cases, frame and tank in my opinion.

    I always preferred running Woodcraft case savers over frame sliders. Low profile and effective at saving the real important bits that could lead to costly repairs and breakable stuff like clip on tubes, levers and rearset pegs were kept in abundance in case they were needed. I will also say that foldable levers are worth more than their weight in bent/broken aluminum.

    The one crash I had with sliders bent the bolt to hell which was a bitch to remove. YMMV

    The new low profile savers from Woodcraft look like a good compromise...kinda cone shaped with the peak cut off.

    I run tank and fork sliders, both of which have proved their worth. Neither of those have the potential to make the crash worse.

    The concern I've had on some bikes is that the sliders can transfer a great deal of force to the frame-to-engine mounts, breaking both of them.

    Jim Know your grids...

    I see many (to many) of your crashes. Sliders and crash bars help a bunch. I also would listen to AAron on his advise. Don't crash and know your gird positions and all will be well!

    another suggestion... not putting 400 ft lbs of torque on your controls fasteners like clip ons or lever guards.
    Also softer fairing stays that can be "bent back" or replaced easy.
    Not really a fan of sliders that use engine bolt areas to fasten.

    Who is going to be the first to patent "airbag technology" for bikes from a crash? :D Imagine the paint, body, & stickers it could save! :D
