Engine Covers

[moonym20]

Random thread (c'mon its early in the morning n im bored!)


I seem to have noticed lately that most big bikes that hit the deck usaually damage their engine covers such as the crank case spilling oil everywhere, making a mess and rendering the bike useless.

how come is it that manufacturers build these cases to be so fragile and brittle? from pics the covers errode away very quickly when they kiss the road or just smash when they hit the deck.. just wonder why?

I know there are covers out on the market made from better metal and formed in a better way, just wonder why the hell the manufacturers don't build more sturdier engines

I would have thought its down to cost and weight.

Not use any cast metal available now would survive 200kg or so of weight pressing down on one side whilst being ground down on the other on what is in effect a very abrasive grinding stone.

If you want the engine to come away with just scuffs and not actually holed buy a V-twin. The engines are far narrower and don't often grind right through.

This is what R&G's are for

You can buy carbon fiber covers as a replacement and they can with stand the impact and grinding, but are only made for popular sports bikes such as the R6 and R1.

Mine are made of Magnesium. I know it's lighter and more expensive but don't know if it's any stronger.

Hi,

I think Magnesium is stronger.

I think you can also use Kevlar... But don't quote me on that

You can certainly buy molded carbon fibre stick ons that protect the casing from grinding (and look very trick).

Just only for popular bikes though. Want some for the CBR. The gen cover already grounded when i lowsided, and that WAS with R+g's

It's a proper git trying to get hold of new ones too. Mine are just scuffed from a low speed off with the previous owner, and I need a new alternator cover and clutch cover. I'll be f*cked if I can find any undamaged ones on eBay, and when one does pop along, it goes for extortionate money, because everyone wants it. And Yamaha want an arm and a leg for it as well.

[Visitor Q]

This kinda thing.

Would make my bike look so much sexier. Just cant find them about for them seem to only make them for tarts handbag bikes.

Wouldnt pay more then 30 quid a panel anyway.

I think that even if they used the hardest metal known to man, it would still scuff upon contact with the road and 99/100 people would replace the part once it looks 'dropped' anyway.

Granted it would probably save the engine from actually being holed, but when you go up to the parts counter to find out the cost of a 'Hafnium-Carbide-Tungsten-Titanium-Aluminum-Magnesium-Boron-Alloy compound' engine case it would require you to sit down sharply!!

carbon engine guard made for new bikes only?? my arse. i can get em for my nc30....a 16 yr old bike(well almost, birthday is soon, must get some goodies)

but yea, get engine covers(if poss) and r&g's, also, dont fall off, ive heard thats the best way, but ive yet to try it.

I've found one for £30 The breakers that bought my ZXR have a FZR for breaking, a quick email and its available

I'm buggered if I can get the last bolt undone, copious amounts of WD40 and still nowt

I am suprised that its a part that will get grounded and broken if the bike falls or skids, so why not more available

Got carbon fibre engine guards on my nc35. Shouldnt be more then a ton, look very trick and also look like they could take alot of punishment.
Some bikes seem to insist on having the engine cases uncovered by fairings whilst some cover them up, the uncovered ones always get damaged in crashes, anyone know why they arent desgined covered?
