Anyone seen these yet? No mention of weight

Someone told me magnesium (even protection coated) parts are difficult to handle in street use...
They need special attention and special care, couse magnesium is always in love with corrosion!
I will read about it! May its a good BST alternative ;-)

Yes, not much info at the moment. I don't think I would bother with carbon wheels on offer at the moment, the weight difference is next to nothing, ok if you are racing on a track but that's about it and even then, I have read a few things on line about them cracking!

Magnesium is very prone to corrosion. It needs specialist treatment periodically which is typically a chemical paint strip, an alumina shot blast, a dye penetrant crack-test followed by a chemical dip or chromite coating before repainting. If you use your bike for motorsports, on track or LSR, you cannot skip this and I wouldn't trust any Mag' wheels that were not 100% up-to-date with this procedure.

I had Marchesini's on my Hayabusa, they were brilliant but expensive to buy and maintain. If you chip a wheel you cannot just touch it up.

No disrespect intended, but thats retarded. If Mag wheels are difficult for street use, someone should tell Ducati/Marchesini. All of the Marchesini equipped Ducati's have Magnesium wheels. They have been putting them on their Superbikes forever. They are powder coated against corrosion as much as the JD Power rims listed above are.

Go to their homepage (Which took me FOREVER to find a while back). I did the math and the kg to lb conversion. The Carbon Ones are slightly lighter than the Mg ones. But hardly anyone has the Mg ones. And they make them in several colors. I LOVE the gunmetal grey ones...Imagine that as a contrast to the '16 frame.

Homepage is bad a$$....... JBK English ? JB-POWER

Hey Nola may you are right with the leader marecesini but like you know Carbon is not Carbon and mag rims are not always mag rims;)

The coating is very important Ill agree with that, but the context was that they are difficult... not imposible for street use.
Or do you think that magnesium is 100% usable like aluminum or Carbon rims under all street and weather and care conditions?
That JB says its coated is fine but its not any quality feature that delete all advices out there..
Or speaks for all mag rims...
Magnesium is very interesting like I said but I need a lot more informations about this crazy stuff

I have had no experience with magnesium wheels but i do know it is very prone to corrosion once the protective coating has been scratched.
As unlikely as it sounds the 1978 Honda CBX 1000 weighing in at around 600 Lbs has a magnesium sprocket cover and alternator cover , once you have polished off the black coating from the sprocket cover to try and achieve a chromium like finish it will revert to a horrible dull grey /white oxide within a few days .

How do I know that the CBX has real magnesium covers ? I had a broken sprocket cover from a CBX and had read that they were magnesium so I tested it out by holding a blowtorch on it for a few seconds , It caught fire and produced such a blinding light that I could not even look at it , as my bike shed was next to the river I had to drop the cover into the water to extinguish it .

I have magnesium wheel experience.

What you want are FORGED magnesium rims. You do not want CAST magnesium rims. The Magnesium rims that come with Ducatis are FORGED and they last forever. I've raced on them and stored them outside. They hold up forever. In fact, on zxforums, someone has a Forged Magnesium wheel from the ZX7R era in the 90s that's still rideable.

Cast magnesium rims, on the other hand, are only good for 2 seasons before they need to be inspected. Marvic will only warranty their CAST magnesium rims for 2 years.

Buy FORGED Magnesium rims and you are set.

Also, as mentioned, you do want to X-ray CAST magnesium rims if you hit potholes etc.

In my humble opinion, I would go Magnesium rims over Carbon ANY DAY OF THE WEEK. If a carbon rim fails, which it has on many occasions, on both amatuer and PRO level, You are royally screwed. Given the speeds of the H2, I would not want to have a carbon rim fail at over 180mph.

Here's a prime example. Talk about a PR disaster.

I don't want to open a can of worms or hurt anyone's business but this issue has been battled/argued already on many forums.

I encourage anyone to google "BST Wheel Failure" and do your homework. Me personally, you couldn't GIVE me a free set of those things.

I have to apologize for a slight error in my previous post. Maxime Berger's wheel was metal actually. I'm looking for the other wheel that failed in World Superbike. I'll leave the other video up just for educational purposes as to what can happen.

In any case you can search for both BST and Rotobox wheel failures and you'll get dozens of results. I wouldn't dare put a carbon fiber rim on a 300+ crankshaft horsepower H2. Buggin'

I will stick with my OEM aluminum rims for now. hahahahahay

This slow-azzed Ducati shredded a wheel. Imagine the Omnipotent H2.

Turbo 329 couldn't agree with you more. They somehow haven't perfected carbon fibre for wheels. Yes they look real cool, but failures are not unusual. Here in Australia occasionally hear about fractures/ failures. Somehow the dynamics and stress/forces don't suit the strength and flexibility I think. Actually a friend mine has a high end mountain bike which had cracking problems with his carbon fibre wheels not long after buying the bike? He had the best available CF for his bike. To me that says if they haven't got it right with bicycles how on earth would you trust them on 200hp + motorcycles!

Tyre changers don't like them either, common to hear cracking or stress marks on even high end CF wheels after tyre changes. Something that you never hear from normal wheels. If I was to change wheels, yes forged alloy wheels would be my choice, but like you I just love the OEM cast alloy wheels on my bike :D

Just out of interest ( not trying to hijack the post) :)I happened to stumble across a tyre changing machine on one your YouTube posts. Is that a No Mar tyre changer? Which model is it?
And how would you rate it ? Thinking of buying one. When you balance do you use the OEM weights in the centre of the rim? And if so how they go?
Thanks
Jeffro ;)

Yes, that's a NoMar Classic with the hitch mount. It pays for itself after a few changes. LOL I LOVE the thing. My wife bought it for me for an Anniversary present. It gets the job done. The bead breaker could be a little better. Technique is everything with the bar, etc. I would recommend buying a cheap wheel on Ebay and practice mounting/unmounting a few times. Otherwise it's awesome. 9.5 out of 10.

I balance with standard weights. I don't like the OEM weights because they scratch the rims. I don't care how careful you are. You have to use a flat-head screwdriver to pry it up. I don't like that one bit.

Oh guys ive read too much today...
My current plan:H2r stock wheels only!!!
No Carbon no Magnesium for this beast.
May my planed 1299s can convince me on magnesium
I have to wait a few years for new high end rims... the thron legacy wheels would be awesome;)

@Turbo329

I went to the site that you got those pictures from and did some reading
like you suggested, and got a little nervous.

But I scrolled down a little bit and found 650ib having BSTs installed on his 2016.
He weighed the stock wheel, and the BST wheel, and found that the BST
weighed 1.5 lb. less.

Reducing rotating mass is always good even when it's only a couple of pounds. In the case of carbon rims though, for my personal taste it's just not worth it. A metal rim will warn you before it fails. A carbon rim will not.


Most guys don't change their own rims. You'll always have that voice in the back of your head wondering if the mounter didn't hack up your rim while installing your tires. You'll never have peace of mind worrying about stress fractures.

I had another comment here. I'd rather just put this.
Research is an invaluable tool to contradict hearsay, rumors and propaganda. If you don't like the other ones at least research what the internet God's spew as fact.

Carbon wheel- Ducati Up North

NOLA
Read with interest your link. I think information is always going to be debatable depending what side your looking at it from. Nothing I believe is gospel, you have to use your own mind, common sense and experience. Yes they may use them in Moto GP and high end racing, but there everything is basically a throw away item. The money is virtually endless. I am sure the wheels would be thrown out if even suspected of an impact or slight damage, who cares just get new ones. But the normal Joe Blog doesn't have that luxury. I don't trust anything/information without having my own intuition and my own intervention and thought. I do know and have seen carbon fibre fail in a wheel (as mentioned in my post) where clearly in my mind a conventional wheel would have deformed and bent, not self destruct. I still say and I believe cf hasn't got the durability, inherent flexibility and deflection capabilities of conventional materials in WHEELS. Somehow the dynamics of a turning mass doesn't suit that material. That's what I believe anyway just my say.....
Good luck to all you CF wheel freaks :D
Jeffro ;)
