Well, they mounted slightly lower than GSG-Moto or Bike Design protectors, so they should work. They are same position as LSL pads I had (and crashed with) and they certainly took contact at right moment.
So I think this should be OK. I do not have bellypan, so I can't say if it is same with bellypan.

Engine casings - definitely yes, I am goint to buy CarbonAdi carbon covers for engine. I learned hard way that to protect right side cover you probably need mile long protector :) so I accept fact that it may touch ground first.

Crashpads I posted - GSG Moto cost 30-35 euro per pad + 15 euro for 3 "damping" caps. I think this is cheap. Mounts for Firestorm, same as older model GSG Moto.
Metisse cost 89-99 euro per set of 2 "shock absorbing" pads. But I do not really like them. No mounts for Firestorm
Gilles tooling pads are same principle as Metisse, but I think cost well over 100 Euro. No mounts for Firestorm.

Lightech supposed to cost 60 GBP per pair of bobbins, but they do not make mounts for Firestorm.

I think I will turn pair of UHMWPE or Delrin bobbins on my old lathe, then buy caps from GSG Moto and then install bobbins on rubber shock like Lightech by turning "sliding bushing" from piece of aluminium or steel. E.g. will use both solutions.
My only problem is price of Delrin on eBay. Or rather price of postage. I want bar 80 mm diameter 250 mm long - this is about 20 GBP but + 20 GBP for postage this looks almost like price for pair of GSG Moto pads. I am thinking hard what to do...In Belgium chances to source right material equals to zero, so I have to rely on UK eBay.

apart from the front indicator, the first thing to hit the ground on mine was the flat ridge just below the rad.
imo they'd have to stick out pretty far to protect everything.
if they save the casings they've done their job cos at least you will be able to ride it home - with oil in it.
You do not have to say anything. But it may harm your defence if you do not mention when posting something which you later rely on in quote. Anything you do say may be ripped to sh*t.

Same here - first indicator, scratch on ridge and cracked clutch cover.

I measured lenght of protectors required to protect clutch cover - on right side protector would have to be hugely long to work. I noticed that clutch cover on Moriwaki firestorm is totally different BTW - I guess we need to ask Gilson why ;)

So I either will put carbon cover on it or will venture into another garage build process to build some protective thingy like distanced aluminium cover bolted on top of stock or something like it.
It's annoying that for almost all sportbikes aftermarket offers clutch case protectors (sliders kind that mount in tricky way round clutch cover) and nothing available for Storm.

the carbon covers are pretty good.

It's different on the Moriwaki as they've cut off the normal cover and welded on a 'door' so they can unbolt it in minutes and change the clutch without loosing any fluids. It's nothing to do with crash protection as the scraps will show! I've got some pictures and will post soon as I sort them out....

Apparently, racers don't use crash protection because they should be going too fast for them to make a difference. :clap: You do see them on bikes though, I seem to remember Lorenzo having some exhaust protectors but I think these were more sponsorship than anything else...

Yes, I knew it was not for crash protection - I was just trying to get more details on Moriwaki storm :)
I always imagined some supetricky slipper clutch-thingy behind that big "door" :)
I admit it, I am envious. Thou I know I won't be able to use proper track bike, but lust still there.

I'm not actually sure what's behind there, but you could be right. As for my abilities..don't think that I'll be using it anywhere near it's potential!

Apparrently if you are not using it aggressively, that is, just pootling along, petrol is sucked into the airbox and it has to be cleaned out! I expect after a few laps with me it'll be swimming in there!

Can't wait though...I'll have some info for this forum soon...

Thanks though!

Similar crash protectors with some impact absorbing rubber listed in the Demon Tweeks catalogue free with this week's MCN.
It's not falling off, it's an upgrade opportunity.

Yesterday my friend from Ukraine - professional motorcycle mechanic, and good one - believe me - sent me set of photos on how different materials sliders react to crash. Those are all bike that he worked on from start to end, some of them amateur racers bikes.
It turns out that by trial and error of other bike shops and his own he narrowed down material for sliders to just 2 kinds:what called here Nylon 66 or Nylon 6-based materieal impregnated with graphite.
Those seem to absorb impact very well and wear on paving during slide rather than bending bolts and mounts. He machining them mostly himself individually for each bike that comes to his hands. But he is not happy with fact that owners of some bikes like Gixxers which seem to have very fragile motor mounts do not allow him to make braket-something thingy and insist on mounting pads straight to engine mount. He said he seen enough broked engine mounts and frame holes.
Anyway - I am going to see him in couple of weeks when I will be attending some yearly meeting of our mototravellers group (not on my bike, just flying there) and he going to bring me few rods of that material.
I also will use that dense construction foamy thing (not sure what is right name - light blue color, it used sometimes between brick walls as isolation) as absorber. It will be ring sitting under slider.

Here is photos he sent me. Pay no attention to text - it is in Russian

http://kickstarter.org/forum/index.php? ... 4#msg31104

http://kickstarter.org/forum/index.php? ... 5#msg31105

and here is why metal sliders do not really work. As you can see - almost no damage on slider. Yep. Because they damaged mounts - no absorbtion of impact at all

http://kickstarter.org/forum/index.php? ... 1#msg31101

and this is LSL sliders. They aborbed impact by...bending all stuff used to mount them. Same experience I had. But at least they do wear off in slide

Yep, same system with Metisse pads precisely.
But even more expensive :sad2

Only replaceable plastic sliders left to make and bolt on (will be Nylon 66). Frames bolted and set. Could be done better but best I can with given materials and tools

Hay! that frame is looking really good but please....tell me you don't blow dry your bike after washing it 8O (hair drier in top top pic) That's just too much love to lavish on your Storm :crazy:

What - me washing bike? I wash my bikes on 2 occasions - if I fallen into mudpit with it (DR800) or if too much bitument stuck to it (VTR).
So, not only not dry, not even wash...it's totally filthy :biggrin Haven't washed it for year I think :lol:

I use dryer to warm up pieces made of metal before spraying them with paint or primer - seems it prevents overspray leaking etc.

I new there would be a sencible explanation. Don't know if I would get much done having a comfy arm chair in the garage though. I think there would be more snoring than spraying going on :wink:
