View Full Version : Frame slider broke on crashing - common?

I had quite a nasty skid a week ago. Wasn't going fast at all. Literally only pulled away about 15 seconds prior yet due to the rain, potholes, man cover (whatever it was), the skid ended up a quite violent. I think me and the bike did a figure of eight on the road. Anyway, the frame slider actually broke in half. Is that common? I thought they were a bit stronger than that...?

Depends on the brand of slider and whether it caught on something.

Not all frame sliders are created equal.

R&Gs commonly broke... so much so that they radically changed the design back in about 2005. Either way, the plastic can still pop off.

The point they make, and it's quite valid, is that they're just there to protect the bodywork if you drop the bike. However, there's only so much throwing down the road that they can take - for that you need proper crash bars.

it's also a point of design, whilst some will stay in place and wear in frictional contact, but break away should they catch or dig in, so preventing the bike from flipping.

Cheers Mark.

crash bungs are'nt for sliding down the road. they are for droping the bike when man handling it hence why you'll never see any track bikes with them becuase there like anchors when a bike slides down the road they just dig and flip the bike causing more damge and possible damage to the chassis

These were the ones from ebay Agy?

True motoslider 'frame sliders' which yours were based on, would snap. The real ones grind down as they slide down the road.

I have the curvy equivalent, and they have been tested on that tarmac surf I told you about ;)

Shoot. Do you think I would have had a lesser accident without? I was riding south but after the skid me and the bike ended up facing north

Yeah I had the second ones (just different brand)

The ones you had didn't mount on a rod right through the frame, this was your issue, and why they snapped. Motosliders from the US, are different. The ones this fella sells are motosliders, and you can only buy them from US suppliers, him being one of them.

IMO, I wouldn't buy anything other than either these or R&G, and even then R&G I have my doubts over, as I have them on one of my other bikes, and they don't do the job they are supposed to do. I have had to modify them to fit, even though they are sold as specific to that bike.

Hmmm don't now what to do now. Sliders or no sliders....? If they cause the bike to flip...? Don't know whether to have them or not??
I'm not sure I understand the difference between those US ones. These ones I had were mounted on a very long screw. The screw and part of the slider stayed in. Just half of it broke of.

Ah I think I see what you mean, it's one rod for both rather than two separately mounted

They are a very useful addition, simply because when you're bike goes over they take the hit instead of your frame and engine casings, bodywork etc. They do occasionally break (thats part of the territory of being a crash bung), some are better quality than others.

Will they always work 100% and prevent any further damage? No. In many many cases they will prevent the damage from being far worse. If a bike is going to flip, it will flip, regardless of whether or not you have these fitted. Very rarely will crash bungs make things worse.

I've used the R&G to good effect, also the DHM Motrax ones survived many a race crash for me. The Motosliders ones are fairly sturdy and also worth the money.

So the conclusion is, I should have some.

So the motosliders - is that a specific brand name?

These are the exact ones i bought:

So these are better than nothing, but their weakness is in the length of the bolts and the fact that they are separate bolts. I had DHM bungs of a similar design fitted to my race bike, they worked well a number of times. Other times the bolts bent.

It could be argued that the Motosliders type are a better stronger design, but to be honest it really depends on the type of crash they are involved in. If you've already bought these then you could go ahead and use them, no point in wasting £30 or so.
