Warning Dymag wheels
I purchased a set of magnesium 5 spoke Dymag wheels from Superbike racing november 2000 for my ZX-12. When I purchased them I was advised by Dymag's representative that the wheels were rated for 300 H/P. I was advised in January 2002 by Andrew at Superbike Racing that there had been rear wheel bearing failures on some high H/P Hyabusas used in drag racing and that Dymag was furnishing a upgrade kit consisting of new stronger bearings and sprocket carrier under warranty to all ZX-12 and hyabusa owners who had purchased wheels. This was posted on two websites by Superbike Racing catering to ZX-12 and Hyabusa owners according to Andrew. I have tried repeatedly to get theses parts through Superbike Racing. When I called yesterday Andrew advised me that Superbike Racing was severing theyre relationship with Dymag and would not be selling or servicing Dymag wheels anymore. He further stated that Dymag was fully aware of the problem but was dragging theyre feet and refusing to do anything about it. Andrew stated that this is a real safety issue and that Dymag has been furnishing substandard bearings for this application. The man was obviously very upset with the way Dymag had treated his company (Superbike Racing) and his customers concerning this and other quality issues. I WOULD STRONGLY ADVISE THAT NONE OF YOU BUY DYMAG WHEELS FOR A ZX-12, HYABUSA, GSXR-1000 OR OTHER HIGH H/P APPLICATION UNTIL THIS IS SORTED OUT. If you know someone who is racing Dymags on a ZX-12 or Hyabusa please advise them there is a potential safety problem. I left a e-mail on the Dymag factory site concerning this problem today.

Just FYI, there are other brands of wheels that have the same problem. The "hot" fix is to install 2 bearings in the cushdrive. More support = less bearing failures! I just never liked the fact that Dymag had only 2 authorized distributors here in the US. Leads itself to monopoly practices!  If you had a run of the mill GSXR there are tons of part available, but try to get something thats listed but they dont sell awhole bunch of! :roll: I waited 4 months for Superbike Racing to tell me they wont order the wheels for a bike I have. Screw them. Dymag has always acted like they were the only wheels available in the US. Glad we have lots of choices now!

Good information- thanks for the update.
FWIW- A friend of mine just had _stock rear wheel bearings fail_ on his 2000 ZX12 causing damage to the swingarm too. Of course he drag races his bike (several hundred high 9 passes) including a handful of Maxton/ECTA 194-mph passes and 14,000 miles on the odometer.
Next time you racers or high mileage guys swap the rear tire be sure to inspect the bearings while you're there.

I have a problem with a Custom Carbon wheel I purchased from Superbike. A few weeks ago someone on labusas posted some information.
Andy Goswell of Dymag will handle your replacement if you email him at
andy.goswell@dymag.com
Every email he answered promptly for me and supposedly, my cush drive is on it's way to me as of July 22nd. It takes time to get from the UK to me based on past experience but once again I will remain hopeful until proven otherwise.
I'll post when I receive my parts, or not.

50 ft lbs of torque max....
I have the three spoke dymag wheels on both my rides. If there is a concern with the bearings, then replace them with better ones. There are only so many bearing suppliers out there. Also it states strongly that you are not to torque your axles over 50 ft lbs of torque. I would hazard to guess that some wheels are over torqued when taken in for tire changes as they put their min wage tech on the tire machine. Only a thought. I have not had any problems with mine, then again I am not dumping the clutch at 10000 rpm against a slick either. Also I check the wheel bearings every once in a while for slop or clearance. This would fall under pre-flight check.LOL
Just my humble opinion.

Thanks guys for the response. I have sent two e-mails through the Dymag website with no reply so far. I will try e-mail to Andy Goswell directly. Andrew advised making a phone call to Steve Turner at Dymag. The number he gave me from the US is 011 44 1249 655 481. It was obvious Andrew was extremly upset with Dymag in my conversation with him. He made some very serious charges that Dymag was screwing around and not resolving what he considered a serious problem on wheels for ZX-12's and Hyabusas. He also stated that Dymag was furnishing cheap 3rd world wheel bearings which carry no certification and are substandard. I have not had a wheel bearing failure but I have sidelined my rear Dymag until I get this resolved.

I have been watching and listening all of the many issues, articles, posts etc. I have seen and heard of over the past few years. The Dymag wheel looks like a nice product. But I don't understand why or how they are still in business. In every case that I have actually seen involving Dymags the customer seems to me the final step in the R&D and manufacturing process. There has always been an issue with bearings, spacers, seals, the hub or some other problem.
Does Dymag actually try installing their product on anything?
I contemplated buying a set of Carbon fiber wheels from Dymag. But based on all of the issues I have seen, I would be better off rolling the dice or betting the money on 11 black in Vegas. I would suggest Dymag try paying for R&D and actually finish the R&D process and product prior to shipping. Kind of like MUZZY usually does. Of course MUZZY takes shit because of how long it takes to get the product out sometimes. But given the choice I want the box to arrive, install and play!

I, too, sent Dymag an email asking for the upgrade kit and got this reply which I think clarifies things a little.
"Thank you for your email. Please let me know what colour your wheels are and I will send you an upgrade kit accordingly. The kit was primarily developed to allow access to the drive bolts without removing the wheel, so that they could be checked for tightness during routine maintenance. A very small number of customers have had one or more of the drive bolts loosen, which if not corrected, imparts undue load on the carrier and bearing arrangement, resulting in premature bearing/carrier failure. As a precaution, we also took the opportunity to upgrade the bearing. It is not clear why this occurs in isolated incidents, but as a responsible manufacturer, we took the decision to issue a revised kit to any customer who wants it. The problem we have is that despite numerous requests, Andrew Wright refuses to give us any USA customer details.
To keep this in context, I can re-assure you that the vast majority of our customers including some prominent race teams have not had a problem with the drive bolts and some have declined the upgrade offer as they are happy with the existing carrier design.
To put you in the picture about Superbike Racing, last year we took the decision not to renew their distribution contract as we wanted to expand our sales channels into the USA by allowing regional distributors to buy direct from the factory. As a result communication between SR and Dymag is understandably difficult, whilst we seek to resolve the outstanding issues between the two companies.
Please let me know if I can be of any further assistance.
Best regards

Guys, when I first got my (5 spoke "Racing Mags") in Dec. 2000', I had the same problem. The Allen bolts that hold the hub together came loose without my knowledge. I was back road strafing with a group, when I noticed a "weird" feeling from the rear end. Pulled over & found the hub coming loose allowing the carrier/bearing to "float," which destroyed the sprocket carrier by the time I got home. Apparently the factory had not "Loctite'ed" the bolts, allowing several to come loose, the hub separated, & this allowed the bearing & carrier to float on the axle. Luckily I did not discover this at top of 6th gear...
At the time Island Racing Services (where I bought mine) David Hirsh took care of it under warranty. I was told my Ninja was "the first ZX12R" with this issue. The 99' Hayabusa's also had the same issue, & it happened on ALL bikes, not just the big HP bikes. IRS took care of my warranty in about 5 weeks during the 00' winter (Nov./Dec.) Apparently the reason I had to wait so long, was for a new carrier to be designed, molded, & cast for the ZX12R.
I got the new carrier in Dec. 00', & haven't had a problem since. It has the "holes" for tightening the hub bolts, & I check them occasionally (chain adjustments, etc.) FYI, I Loctite'ed the snot out of them so they won't come loose again. Just recently, IRS also dropped the Dymag product line due to "customer service issues." I don't know the details (speculation) excepting it sounded similar to what others experienced with Superbike Mike.
There are several new distributors for Dymag's, here is one local to me (SF Bay) : http://www.ema-usa.com/ I e-mailed them last week to see if they can get Dymag's & Talon sprockets (Dymag OEM), & they said they can get Dymag & Talon no problem.
Hope this helps clear up some things...

I assume you meant superbike racing not superbike mike although they might be interchangable as far as customer satisfaction is concerned, or so i have heard.
i measured the upgrade bearing and hub. the replacement hub is a stronger casting to accomidate the larger bearing which has a 7mm larger diameter and is 2mm wider. I installed the new casting last night and everything fits perfectly.

Cool, spin that sucker on the axle & see how good the bearings work. I was amazed it took several minutes for mine (front) to stop once spun by hand. Cool...
Oh, & yes I did mean Superbike Mike. I saw on some website (this one?) he dropped Dymag from his line (as well as IRS) due to customer service issues too. I can't confirm this. Wondering where did you buy yours from?

I bought my wheels from my dealer who got them from superbike racing. Customer service issues have been a constant problem with Dymag in the United States. Motorcycle News ran a article concerning poor customer service from Superbike Racing a few years ago. I always assumed it was an issue with Andrew at Superbike Racing but when I heard Island Racing was also no longer selling Dymag (theyre choice) because of customer service issues I have to question the commitment of Dymag to customer service. If you want to hear what Andrew at Superbike thinks of Dymag support call him. He will talk you're ear off about all the problems he has had getting problems resolved. It took me 12 weeks to get my wheels 2 years ago but the fit and finish were outstanding and I have had no problems with anything except getting the upgrade kit. It took me 8 months to get the kit and I was only suscessful finally by going directly to Dymag. Availability of sprockets has also been slow through Superbike Racing.

Well, as a dealer with Superbike Racing, i must say that Superbike Racing has there own problems with dealer service much less a regular guy!!!
Secondly some people, when a "monopoly distributership" contract runs out and is not going to be renewed turn to destroy the product image, before others like myself, can get the wheels for the same price that he got them. Well, the days of Superbike Racing being the only company to import dymags are over! The truth that motivates people is often times very ugly. That is why God will judge the heart!!!!
