[Popeye]

do any of you have them fitted?

do you have to do much cutting of the fairing?

are they worth it?

where do they fit?

how do they work on the trellis frame?

would you?

Ta muchly people.

Do more harm than good from what I have heard and seen. The ones I have seen bolt direct to the frame at one of the engine mount points, and required the fairing to be drilled, saw the result of how they "saved " the bike and split the tube on the frame and also destroyed the fairings, bike written off

Popeye,

Here's a few pics from my lowish speed off at Croft 2 years back with bungs fitted.

Both Felix and myself have 'tested' the thru-the-frame concept and the general concensus is to ditch the idea in favour of a sturdy clutch cover and reinforced (Kevlar tape) bodywork.

When/if the bike slide across the tarmac and then inevitably hits the curb at speed, there's only one result which is shown in my first pic here

[Guido]

This is what the bung looked like...

[Guido]

This is where the Cyclecat design ones go through the frame. The other side of the replacement engine bolt appears through the plug in the back of your battery try (i.e. your battery needs moving and to be of a smaller size).

You can see how snugly they fit up against the frame lug.

Well imagine what happens when you get the stresses off a crach and the sideways motion on the bar as shown in my first pic.......YUP, you get that frame lug bent quite badly neccessitating complete removal and rewelding at an experienced frame shop....

Felix's off was at over 100mph and his lug was pretty mullered afterwards whereas I got away with my mine

Hence the Clutch and reinforced fairing theory......

Hope this helps...

The R&G ones for the 748/9** series look better with an extra cnc bracket that bolts on to one of the frame members, but still got to drill fairing which is why i never bothered on my 748s.

I do have the monster ones on my S4r now though and it looks like the bung is desgned to break off in a high speed crash thus saving the frame I hope

Heres a pic

one more

[Felix]

As Guido says, they DON'T break off, just bend and damage your frame. The frame is not what you trying to save anyway. It's not like on a inline 4 where the frame is very exposed. On a Ducati, the frame is well inboard of many other bits. If you have a faired bike a reinforced fairing at strategic places is the best in my opinion (and I've a few crashes, see race section).

[Lee1980]

I know what your saying, I mainly got the bungs for low speed drops say below 30mph.

Looking at the the bolt that goes thru bung into lump of steel in the pics it is quite short, and the bit that passes thru the bung is long hoping the bolt and bung will come away leaving the bar intact, instead of twisting the frame lug in a high speed get off or if it say hit the kurb.

Best not test it, mate.
