This isn't a wheel problem... it is a sprocket bolt problem.

I've had multiple sets of Tusk wheels for a 125, 250F, and my 450 and haven't had a single issue. mind you i always inspect them before every ride and before each time on the track.

I've destroyed more stock wheels and hubs than any after market brand due to hub, rim, or spoke failure and/or sprocket bolt failure. Many times aftermarket sprocket bolts are not sized properly for the hub and that can cause an issue with the bolts coming loose, shearing off, and coming apart.

More than likely it was a maintenance or fitment issue that caused this.

Lets see 5 pages of people all in agreement that the bolts and sprocket design is the problem, yet the OP and his buddies scream and yell no way. Why did you ever start the topic to begin with?? If you wanted to just bash Tusk wheels then start your own site "tuskwheelssuck.com".

The facts

Elongated hub holes = Loose bolts.
Fretting on the sprocket and hub = Loose bolts
Sprocket does not has a full mounting ring = Sprocket flexes when chain is tight
Wear on C/S sprocket and chain = Lack or impropper maintenance

What a bunch of Fucktards!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Pretty sure everyone is in agreement that it's a bolt/sprocket issue and not the tusk hub. Myself (OP) and buddies havent argued that. What I wasn't agreeing with Peelout on is the fact that he says we don't know how to tighten and check bolts. Which is an insult and untrue. There were things that caused the bolts to come loose within 30 minutes of riding and the result is documented, which were identified in this thread. Fucktard.

If we could only get the owner of Vortex to chime in here, we could probably get another five pages.

Ok. If you think it's a hub tolerance issue you gotta get a tusk hub and check the tolerance. If you can't test it you'll never know and you can deduce that it was cheap sprocket bolts.

you get what you pay for period. ill never buy cheap wheels again. bought some dna a few years back. the bearings sucked and were a oddball size to replace as well. rims were like rubber and bent easily. I neverhad any problems with stock wheels of excels or higher quality wheel parts

Stop it man, those tusk are better than a60 s, or ltx lololol, theory, if you can afford $500 wheelset , you can afford $500 more for quality.

Just thought I'd point his out.......Fully aware this is NOT a TUSK hub, but interesting concept design with regards to hub and sprocket contact area.

This photo is from the CR 250 Full Tilt Build, Interesting that this sprocket is designed much like the sprocket in question on the RMZ. Fully aware that were talking about completely different bikes with regards to weight, torque and horsepower.

It also appears that the hub is also machined so that there is no contact area between the sprocket bolts, or very limited contact in a full circumference on the sprocket.

.
If you look at the pic, you'll notice the hub still has shoulder at the ID near the bolts.this would tend to prevent the rotational stress which would loosen the bolts

These aren't DNA wheels. They're TUSK....can't compare cheap to cheap. Never had anyone I know complain about tusks. Have heard horror stories for DNA. No experience tho. Heard this horror story with tusk, but MXA swears by them. Those guys usually get it spot on. Also I flat spotted a prowheel rim after the first ride. Won't be buying anymore of those.

Doesn't prove the Tusks are poor quality either. Of course, the Talon/Excel combo would be bore durable and more importantly, lighter.

In my experience, the Tusk wheels are comparable to stock in terms of durability.

Damn I'm going through this now. Buy the tusk rim and spokes and lace to my hubs for $300 or send my hubs to Ksr to get their bulldog spokes and DID rims laced for $499. I'll only have this bike another season but I need new wheels and can't make up my mind.

I don't have an opinion about what could have caused it, just a few questions. That looks like the Vortex steel sprocket. I was told by an old timer one time that it's better to run the steel sprockets with less chain tension than aluminum because they don't flex, they just snap and when they snap, they take everything out with it.

this thread is a good reminder of how important it is to properly torque your sprocket bolts bro

I've never had an issue and I can't remember the last time I checked sprocket bolts other than when mounting ... you guys must suck at motorcrossing Silly

I've run a set of Tusk Wheels on a CRF250R... zero issues. Look and work great.

Hopefully Rocky Mtn sends out a tusk discount code for the holidays. They emailed one two months ago and it expired.

Have had 4 different sets on 4 different bikes with no problems. Just wish they made a pair for my RM250 smoker!

I'm going to blame the rear sprocket design on this one.
A couple of years ago, I owned a YZ450 with STOCK hubs. I ran a sprocket similar in design to that where it only made contact with the hub at the bolt points. NOT ALL THE WAY AROUND the circumference of the hub. I constantly had sprocket bolts coming loose no matter how tight I tightened them. It finally took out my rear hub one day in a long moto just like yours did. I bought a new hub, and switched to a normal design rear sprocket and have never had a problem since. Just thought i'd share that.
This poster here is absolutely correct here.......the sprocket circumference on the hubs not fitting tight leaves only the bolts doing the job.....currently i have 6sets of wheels....KSR built SmPro....Rad Mgf.(d.i.d dirt star)....2 sets of tusk...2 sets of stock wheels re-laced with Buchanan spokes.....i ride on SX...Ax...and Mx...and never a issues except when tire pressure goes low and i land on a rim lock...then i bend a rim.......i check my sprocket bolts and spokes EVERY ride...and they always are tight...but i lost a rear wheel like that 1 time on a very large quad like step up to double down and my chain may have been tighter for that kind of landing...and i tore the sprocket clear off the hub...junk ass Tag sprocket......im gonna put 25%of the blame on lack of inspecting the rear wheel every ride and 75%on that sprocket......we have a few kids running around on tusk wheels and they hold up fine...they go big on all the bigger hits .... from the pics their was definitely movement on the sprocket...i use DirtTricks "Ironman" sprockets...light as aluminum but surgical steel...and the sprocket circumference is mated to each standered wheel hub..no movement....ive broken 2 sprocket bolts during a moto and sprocket was still tight to hub......the Ironman sprockets increase wheel strength i am believer in that and they will outlast any other sprocket 5times over thats a fact..and keeps chain wear down......

Bro you do not have to remind us that you launch 220 feet to square edge bumps and explode 400 wheels per year on Cali concrete. We get it, you and your squad are absolute maniacs.
