Crash Knobs friend or foe ?

[Mozzie]

After a recent off , Lowside cornering in drizzle,my bike slid across the road slower than it would have with out crash knobs, but once it hit the dirt it dug in and flipped the bike and destoyed it. The bike would have slid alot quicker without them and more damage to the side and maybe run into something further on, But would not have fipped and wreacked the bike all over. Damned if ya do damned if ya don't I suppose.

[clarkey]

Damned if ya do damned if ya don't I suppose.

Got that right , i have had one saved in the garage , and one destroyed after a flip so i guess im 50/50

[Johnny]

I will never fit them on my bike again, I know that..


Sorry to Hear Mozzie, glad your allright mate..

I'm kinda leaning that way me self

[Kat00]

I have no doubt in my mind that if they wernt on my bike it would be rooted now, no doubt at all. They are the luck of the draw, a necessary evil....

I didn't even know you had an off mate, you alright?

[zRoYz]

At the track they can be a help but as you have found out once they dig in they flip the bike & do more damage than there worth. Pot holes & gutters also tend to rip them out & parts of your frame on the road.

[Mozzie]

I
I didn't even know you had an off mate, you alright?

Yep fine as. the bike aint but.

[mick]

Oggies are designed for low speed low sides and pretty much make any other sort of spill worse. I got lucky once and picked my bike up without any damage, next time I might have a story like yours. Sad to see another bike fallen, all the best getting it back to life.

[Pokey]

I've heard on the ZX 14 forums of badly designed frame sliders snapping off engine mounts in low speed crashes, my oggie knobs appear to be the busines though with additional bracing across the front :ayyy:

[WET4URacing]

do GP bikes have em??????????

[_chado77]

my cbr slid and flipped with out them on my off at T4 at EC..


as said above luck of the draw IMO..definitely be a live safer for off the side stand type falls(not ive ever had them to know):confused1:

interesting point wetty but how much $$ do GP teams have vs us the average punter

[WET4URacing]

so they dont have em coz they cant afford em?????

watch a 125 or 250 crash and you will see them slide for ever. they dont have oggys and they have almost no steering lock.

[_chado77]

$$ & gp.. if its kawaski you are talking about you may be right about GP teams not being able to afford them:lmao:

from a GP perspective due to sponsors and appearance etc a slide or flip will still require all damaged parts to be replaced therefore negating the use of them.. where as a punter such as us, will more then likely fix whats nessacary then ride again:dohsmiley:

[WET4URacing]

sliding and flipping. sliding may result in returning to the track and finishing. 1 point can win a championship.
flipping , walk away and get the scooter taxi to take you back to get your arse wooped by the boss

[Captain]

I think you can just about flip a coin and decide. I have heard tales of bikes flipping because of them (although many of those times it's an assumption, who knows what really grabbed) ... and I have heard of bikes being saved by them.

I have fitted a set, as the balance of all I heard and read suggested that they are more likely to do good than bad. But you could certainly be unlucky.

[Cedric]

Sorry to hear about your off, but glad you're okay..

There are thousands of different variables which could lead to them either being a help or a hindrance. I fitted them to my roadbike, on the basis that I'd be more susceptible to dropping at a standstill, whereas to my tracky I didn't fit them in the hope that she'll just slide.

Fitting them and hoping they'll help though is like predicting the hows, whens and wherefores you'll crash next.. you can't. Got to decide whether they're worth the purchase price vs how much you think they'll help.

[tazkenny]

Sorry to here the bikes rooted Mozzie :(

I've picked a bike off the ground after it spat me off from a rear slide but it was relatively slow speed. Only damage was a few scuffs. The side would of been wasted without the oggies. I think it's just pot luck.

[hoffy]

depends on the mount I guess, I know 14's, 12's dont like them, so I dont run them, also have a mate on a 07 10R where it cracked part of the frame on a low speed get off...

I reckon its easier to fix plastics etc than it is to fix frame mounts etc, so I dont like em..

[burlo53]

Hey Mozzie.your'e supposed to keep the thing upright!Glad your'e okay though.Don't know if the knobs are good or bad,but they look shithot.When you get as old as me they are good,stops damage when i fall off when i stop.Must remember to put feet down i guess!

+1 I rolled an SV1000 in the bush once doing about 70km/h. All that happened was bent handle bars (that I straightened) slight scuffing on the pipe, the smallest ding in the tank that took me a year to find and a busted foot peg.

I slid my FZ1 done the road and wrote it off, go figure.

Wetty, I know why Moto gp bikes don't have them - wind resistance on a 125 they would slow them down, unless of course they were made to reduce drag:dohsmiley: The real reason is the same as the reason why the dudes never pack up their own bike at the end of the race. Not their bike.

[Ed_GSXR]

I've had two bikes flip over on lowsides because the knobs have dug in.

They'll be good for a very low speed (walking pace) drop but personally, I'm not gonna bother in future.

[LAW]

Why aren't oggy knobs designed to skip over obstacles and not bite in, like maybe make them so they are rounded or tapered or flexible?

It's a known problem but the manufacturer just seems to be ignoring it? :confused1:

[wonnaride]

$$ & gp.. if its kawaski you are talking about you may be right about GP teams not being able to afford them:lmao:


Funny you say this as Kawasaki were the only ones who did use them, I think!

[Lopeman]

I think they are good only for a slow speed slide or a drop off the sidestand.

But in saying that if your bike does flip due to the crash knob (very hard to prove, what about rearsets?) you were probably going fast enough to cause a decent amound of damage anyhow.

That doesnt include breaking engine bolts and frames though, thats just bad design.

[Captain]

You know, I've seen plenty of motoGP and WSB crashes. The bikes often slide on the bitumen, and that's where if you have knobs, they could prevent a lot of damage. Then, when they hit the ripple strips or the kitty litter they start flipping .... and they don't have crash knobs.
On top of it all, I'd suggest that crash knobs rubbing on the bitumen help the bike slow down, so it's less likely it will reach the ripple strip etc where it could start flipping.

I'm sticking with mine for now.

Given the track is 12 mtrs wide, what makes you say this, rider coming off at 20ks p/h maybe ?.

[Falco]

I cant see the need for Oggies on a road bike, that why I buy insurance every year.
Even if its a low speed slide, chances are its going to slide for at least 10 meters and hit something anyway.
Either way, if the unfortunate happens out on the road, I dont want it back.
As for the track, maybe sliders on the forks and big arse swing-arm pick ups may aid marginally.

Oggie Knobs.........over rated for mine.
Had them on a VTR once, yeah sure the tank did'nt get damaged but the Oggie mounting bracket chewed into the frame instead.




No good Mozzie, what happens in a couple of weeks when we come and visit?

[Kimbo]

Friend.

[Captain]

Even if they don't stop the bike, any bit of slowing down will help.

I know of one rider on last years' snowys trip that had an off, and only due to having these knobs fitted he was able to continue riding. Losing your bike in the middle of nowhere would have been a 'slight' inconvenience ...

[1down5up]

well after reading the thred i am in 2 minds as to getting a set having never used them i thought they must be ok to use but reading what you guys have said i think ill keep my cash and keep paying insurance ..............dose insurance give you a discount for useing em like with a alarm if you get 1 fitted ?????? if they did i would use em

[James]

When I had a low-speed slide on my Firestorm In October , they saved the rear end as the mirror and knob held it off the ground. So just minor fairing damage and a $650 repair bill. Without them I would have dented the cans and tank.
But I'm with Falco - for next bike if I do crash it - I want a new one :ayyy:

[pan]

I agree that they can be helpful and they can be destructive...


... though mine are a little different. I have mine for the bling factor, AND they increase my visibility at night

That sounds pretty sensible to me.

All good mate, A mate and a rat up here can't make it and is lending me his bike . Same model and colour too. I will be riding alot more care though.

[phizog]

They are there to stop damage from silly minor damage. Pouring rain and hitting the curb at a bad angle, went straight down at 5kmh. No damage at all though, apart from lots of dirt in the oggy. Would have cracked the fairing/indicators for sure otherwise.

As for crashing at a decent speed.. depends if theres anything to dig in around, but if you're crashing at decent speed its going to be bad anyway.

[Boxer]

Nah, I wouldn't bother - especially when they are built in:lmao:

The Ducati oggy knobs sit under your fairings to protect against frame, clutch and clutch slave from damage in a spill even foot controls i guess but your fairings will still get rashed or cracked...

[Kat00]

You would not believe just how much damage was saved by these things when I got knocked arse over head on the F3 a few weeks back.

Granted, I was only doing 15kph.....apart from the small graze on the ducktail and bar end, you wouldn't know the bike had been down........Sato pegs played their part too. Got home, gladly put a new oggy on and peg.:ayyy:

Bugger Mick that sux dude.....

[Mr.Ed]

Crashed twice (one on each side - to balance it out) and it saved me a lot of $$... I also had the swing arm pick ups and a nice, beefy rearset. All together made for bugger all damage on the bike... Only small scratch on the tail and that was that. One of the crashes was a low side at around 50-60km/h. Worst damage was a toe peg snapped off.

[Sprinter]

How can you know its the oggy knob making the bike flip?

[Mr.Ed]

They'll get bent or simply snap off (sometimes even taking a piece of your frame in the process). I still rather have them though. Just not those really long ones.

[Sprinter]

Sorry but that doesnt mean the knob made the bike "flip". It just means the knob was also damaged.:confused1:

[TIGRRR]

After accesssing the damage from fall at EC on Sat, T5 at about 110km/hr....i have to give OGGIES two thumbs up....they took much of the carnage, half worn down....bit of damage to pipe and fairing but over all bike is still ridable... I have no doubt would be a lot worse without the OGGIES....

[Captain]

I have a set of rather cool-looking R&G Aero sliders

And recently came across this rather reassuring comment/pic on the CBR600RR forum:

[Turtle]

Don't have them on my Roady because if i crash it i want MAXIMUM DAMAGE........(better chance of write-off) But on the trakky i have "Motivation" sliders from the States.....Great sliders.....

[Mr.Ed]

Never thought about it like that... but I must say it makes perfect sense!:n:

[Johnny]

You mean you didnt want to cut holes in the fairing to fit sliders to protect the fairing :confused1:


:dohsmiley::lmao:

Not Bad...'eh ??

:dohsmiley::lmao:

No, you don't have to cut a hole.......i just don't use them on the road.......if you use them you're just helping the insurance company....

[Cedric]

This is true. But you're counting on the fact you're going to have a fairly decent off than simply drop it by slipping your foot on the gravel when you stop..

[Turtle]

If its not a write off the first time ....drop it again......

[Cedric]

:lmao: So you're the reason insurance premiums are so high :D

[*Oggy*]

I use the R&G engine protectors... Dont stick out like the Oggy knob ones.... bit more subtle and wont dig in to flip the bike.

http://i113.photobucket.com/albums/n237/oggydownunder/RG.jpg

[Big Lunt]

Turtles got my vote

But then again it if causes the bike to flip that would work too Turtle!!!!

[Turtle]

:lmao: So you're the reason insurance premiums are so high :D

Only ever had 1 Claim............:)

Yes, BUT:

1) Those look like they only protect the motor case, they surely won't offer the kind of protection you will get from longer knobs.
2) Are you not concerned about the way they are secured? What if one of the bolts were to bend badly, or snap?

I was pretty much set on getting LSL sliders, as they look the best - and work as a knob AND engine case protector - but there was wide concern about the bolts going into the engine block (kinda like yours)

[Johnny]

:lmao: :lmao: :lmao:


Keep telling yourselves that they will offer protection .

The only protection the above pictured will give is, protecting your wallet from overflowing, but hey, we believe ya :lmao:



:ayyy:

[Big Lunt]

Agree.........

[Pokey]

I've got a similar protector on my R1, it covers where the clutch cable attaches to the engine casing and has handled a number of tests well :ayyy:

[SmiddyR6]

I lowsided at over 100kph, the slider grounded past half way.. i rolled down the mountain threw the tree's and bushes, and the bike stoped at the top.. needed a new engine case, lever and bar end.. if it went off the edge 2, then i'd need a towie and the bike would have damage all over.. and also i droped it in the garage on the other side and no damage at all.. ill stick with them..
