Hi,

I’ve been using the forums to research my purchase and any mods I want to add to the bike.

Just bought at 2016 CBR650F. Gloss Black, Black Widow High Level Exhaust, R&G AEro Crash bungs, tail tidy and tinted screen.

Hopefully going to be picking it up this weekend, work allowing.

I’ll post up a couple of pictures when I get it.

Great forum, ful, of good info btw, thanks all.

I agree with Drewster.

Also R&G had issues with the bolts being too short or weak, and the bungs fell off. Google or measure the bolts if you do decide to put them on.

I am one of those whose engine got wrecked due to the crash protectors.
Think twice about mounting one of those. ;)

Even my dealer told me i should not put them on my new one

I had never even heard of these until I got my bike after many years without one. I wondered why people were putting a bunch weird looking knobs on their bikes.

......and many people have crashed/slid/toppled and not damaged anything because the bungs do the job.
If you're in a big crash you expect the bike to get pranged badly and no sliders are going to save the insurance write off that will occur.

Lol they are crap they are probs the most stupid aftermarket design ever. Why would you want to risk smashing engine casings up when they are meant to protect important parts not damage them ? From a normal low side crash you will need replace fairings, maybe handle bars foot pegs ect and be back out in a few weeks. but its a whole write off if the engine goes your choice. The impact
Is directly aimed at cast alloy 🤔. Gb racing covers are all you need. Also insurers wont he happy to pay out if they realise the damage could of been prevented if it didnt have the bobbins.

Lol they are crap they are probs the most stupid aftermarket design ever.
So, it’s not quite that simple or cut and dried whether sliders help, hurt, or are a “stupid” design. The actual name of them gets lost on a lot of people because they buy them to protect their bodywork and that’s not what they are for. They are designed to let you go down and keep the frame of the bike high enough to not catastrophicly fail in a crash and hopefully leave the bike rideable in the event you did go down. They’ve since been bastardized, cheapened and sold as “bodywork” protectors then made to simply bolt on to make installation easier than drilling bodywork and have become longer and have more leverage and in turn less effective and more damaging.

The design of the bike, the design of the slider, the way you crash and where you crash are the biggest determining factors on whether they help or not. On the 650F, and I’m imagining the 650R will be this way as well since the frames are so close, the placement of the middle engine mount, and the design of the engine, create a weak point that even in a slow tipover will most likely will cause a crack in the engine case if you use long, stiff single mount sliders. That’s where GB case covers make the most sense and will be your most effective “saver” when it comes to a low speed crash. Also, a slow, easy tip over is easier on the bike than say a high side and can change what’s covered and what’s not. Your surface will also determine effectiveness as asphalt or pavement will create a smooth surface you can slide over but gravel, sand or grass will cause a slider to dig in and potentially cause the bike to flip or break the slider off.

Take a 600RR for instance and a good race company’s low profile slider like Woodcraft or Vortex where you drill a hole in the fairing lower and catch the lower engine mount and you have a solid place to mount and a very effective frame slider. Doesn’t really save your fairings, and you have to drill a hole in brand new bodywork, but it will protect the bike and leave it rideable in a minor wreck.

So look at the placement of the slider, where and how it mounts and think about the forces it will transmit in a crash. A long, skinny, spaced out bolt attached to a thin engine case is a poor frame slider. However a multi point mount, something designed to “fail” or something low profile mounted to a solid point, it may be worth a look. The current 650 designs, however, leave a lot to be desired.

There is no such thing as a " normal low side crash "......how many times have you lost it on a bike I ask myself ??? .....every crash can be potentially damaging or life threatening, you must remember that.
I've used bobbins on my last 4 road bikes, over the last 19 years, and been very thankful once or twice, that they were on....didn't need them on the chop as it was so low and the footpegs did the same job, or I may well have put some on that too.
I use gb racing covers, have done so for years and have been an advocate of them on this site to others a few times....you are wrong however if you think they are designed to protect more than what they do....they are case covers not sliders.

What even is there to argue about ? All im saying is, they are mounted to a very weak point on the bike! and could easily damage the engine from a average crash or hard fall, (depending on the force ontop of the bobbin),when the bike could normaly be fixed easily, instead of needing a new engine 🤔 . I bet you them last 4 bikes you have owned the bobbins where attached to the solid area of the frame, not directly screwed into the weak cast alloy engine casing. I understand about how you where thankfull using them in the past ,and why you want keep them. But if you think im wrong about what im talking about you are in denial.

Yes I agree with everything you say. I dont think bobbins are stupid and i know what they are mainly for. I just think the common bobbins people use for the 650 are daft.
