Some SUPERSPROX are FAULTY

[@prdoohan]

My last KTM dirt bike had one of these ali/steel sprockets fitted on arrival. I replaced it not long after with an ordinary steel one. I weighed them and the steel one was lighter 🤦. The steel one was much more "skeletal" in comparison.

[@GTMarmot]

May there always be JT sprockets

[@geraldrossouw4425]

Taking a one-piece part and making it a seven-piece part is a high form of stupidity. And I seriously doubt they are lighter than skeletonized steel sprockets like Prox Ultralight or AFAM SLK.

[@MrDJGix]

I have one on my gsr 750. It has been on it for years. Im definitely going to check mine after this though.

[@1312Johnny]

Yes but you can always straighten the hub carrier with a ratchet strap and a tree! 😃☝️

[@NathanielStauber]

The company has missed something here. Either they didn't check the fitment properly or they didn't communicate that an aftermarket or modified carrier is needed for this application. There's no note I could see on the website other than a generic "Clearances must be checked before ordering different size sprockets than originally came on the machine." That's the stock size though, from the information I could find.

[@ANDYblacks13]

agreed ,to me it looks so badly made to fit that carrier I wonder if the part was mixed up before it was numbered? and it actualy fits another brand of bike perfectly

[@warrenlucier5796]

I have one of these sprockets (40T) on my Honda RC51 SP1 1000RR with BST wheels and no interference in that application, so it works just fine.

[@JSmith19858]

I had someone turn up with a Supersprox sprocket for a Tenere that needed the hole opening up in the centre, as it was 5mm too small. Supersprox swore blind that it was correct. Easy enough job except the bloke has already tried to open the hole up with a file

It's possible the aluminium sprocket carrier may springback. No harm in unbolting the sprocket and putting a straight edge on the face of the sprocket carrier, then if it seems ok, take it a step further and fit it back on the bike then check it with a dial indicator.

[@dirtygarageguy]

All of which doesn't change the fact that it's wrong...

[@deanmsimpson]

@@dirtygarageguy Yes absolutely. That sprocket is no good. It needs redesigning.

[@soulcatcher668]

Straight edge will not tell you if it's cracked. That is cast aluminum.... does not like bending. If you know someone with LPI stuff, you could check that out. Not worth sending to a lap though, same cost as a replacement. I would volunteer my services but I am in Canada...... not worth the shipping.

[@cunningpunt]

I'm too much of a mingebag to fork out for Supersprox, JT all the way and D.I.D VX chains. Job done.

[@katywalker8322]

This is interesting. I have had a quick look on Ebay at GSXR750 sprocket carriers. Looks like there is a rib on the edge of the carrier and that is probably what catches on the rivets (later GSXR seem to have an extra sprocket mounting bolt and no rib at the edge). However on Ebay at the moment there is a 2nd hand sprocket carrier with a 43 tooth Supersprox sprocket on it. On that the rivets do appear to be clearing the edge of the carrier (although bloomin close). Someone probably assumed that as PCD, etc, matched then they would fit and never checked the rivets. I will save the tart factor and stick with normal JT sprockets.

[@inferior650riderhd6]

I'll never buy a JT sprocket ever again. The plastic shopper was so tough I damaged my phone screen trying to open it. Gonna buy a supersprox next as the packaging is better

[@chrisdavidson911]

People fitting these to save weight is fantastic. Did they also get the lightest tyres?

[@giedriusbruzas6542]

Ryobi impacts, jesus christ man, we didnt knew the situation was that bad...

[@jimforsyth2.]

Use the top of the caliper to measure steps like that

[@AvenEngineer]

Most aftermarket parts make your vehicle objectively worse. It takes a serious amount of R&D investment to improve on what the OEM already spent on their decades of R&D.

[@ronaldbronson1285]

FWIW, supersprox are OEM on some KTM's. I wonder if the faulty one in the video is a knockoff, there are some fake ones on eBay. I agree with the sentiment though, especially countershaft sprockets that help with sealing.

[@1312Johnny]

@@ronaldbronson1285Do they make ‘OEM’ cams for KTMs as well? 😆

[@jediknight1294]

There's a handful of companies that can do it and they usually work closely with the oem

[@gutserker]

I've seen those before and I've wondered how much of a difference they can really make. I also wonder what the weight savings are. I get that unsprung Mass and shaving grams off adds up, but we are not in race applications.i imagine taking the savings and getting better tires will beat any gains, or brake pads

[@jimforsyth2.]

The noise the chain can make from something wrong in the sprockets or alignment is crazy . You will think you have a bad transmission or axle bearing

[@combatclifton]

I’ve used super sprocket on my KTM for years I don’t have the fitment issues like that one. Must of used 4 sets. I use JT sprockets for practically everything

[@tompackage]

Question, is the sprocket fitted the right way around? I noticed the new one features relief's for the bolts to sit in, does the defective one have the same on the inside?

[@tompackage]

*nut's! 🤦🏻‍♂️

[@noggintube]

I don't get peoples obsession with saving tiny amounts of weight for road use. Fair enough for race teams where fractions of a second can win a race, but paying extra to get to the next set of traffic lights 0.01 seconds faster really isn't needed.

[@williambattersby2096]

You know you can measure depths a different way with calipers which personally i think is easier than the way you did? The opposite side to the way you did the faces are ground and you are able to use them to measure depths of shoulders. With the faces being bigger than the other end you used, the measurement will be slightly more precise.

[@inevespace]

People think they are lighter, but it is wrong. They can be heavy as steel. It depends on design, and I have seen steel sprockets lighter than these combined al/steel sprockets.

[@bailey-cj2pl]

ZF sprockets made in Poland, much better if you want to play the alloy centre game..

[@joshr1444]

Had one explode at 150 mph, so contacted them, and the response was that it had only happened once before, so not an issue😂

[@joshr1444]

@bailey-cj2pl Yes, zf, on my aprilia tuono v4 on the iom. I will never use a 2 piece sprocket again. I am very fortunate the fragments missed my leg, the swing arm and wheel were scrap.

@@joshr1444 Oh my goodness! I won't be using them again. Glad you came away with your leg intact.

[@Googie6767]

I have steel SuperSprox on my Tuono and they’re fine. The people who buy that gimmicky, half alloy, coloured shite are the same people who buy gold and red anodised nuts, bar end mirrors, shorty levers and rim stickers. Now, let me just slip into my flame retardant suit.

[@dirtygarageguy]

"I have steel SuperSprox on my Tuono and they’re fine." - Congratulations of your purchase, that has nothing to do with this...

[@mxdev6387]

Yikes, seems like it was designed only thinking about hubs/carriers with ears for bolting it on and then sold for all bikes without considering fitment issues.

[@vxady123]

Not where I thought u was going obviousl my it his suzuki cush drives.. BUT my mate had one on a wr450 and tore the steal section and studs of the alloy center hud. It bent and tore off. Worst sprockets ever. Oem or get a decent talon or renthal one ffs these don't even lookngood the look like a time bomb...

[@TheNivolo]

You’re talking about different numbers of teeth’s on the sprocket. But it would surely make the most sense if the manufacturer made every aluminum part the same diameter. And every metal parts inside diameter the same on every sprocket? So no matter the number of teeth’s the rivets would always be at the exact same location? Why would the diameter of the aluminum part be bigger on a sprocket with 2 more teeth’s? That wouldn’t make sense from the manufacturers point of view.

[@gafrers]

Well explained and showed. Technical and hands-on videos are the best

[@tones61]

Your mitytoyos are fake? They should flash the 5 dots when battery fitted?

[@dirtygarageguy]

Fake? 5 dots? What?

[@MattJones675GR9]

Without watching ive never understood the stupidity of putting an aluminium sprocket on a road bike. For racing yes i can see the tiny benefit of less weight and inertia it would help reduce a lap time but seems like something Lambchoprides would do on a road going for pointless bling factor.

[@rbz1047]

You didnt watch it clearly its a steel and aluminium sprocket which they rivet together which is stupid and what he explains, try getting over your ADHD and watch the video first 😉 aluminium sprockets have a place in racing, these steel and aluminium sprockets are junk as per what Matt describes.

[@inevespace]

@@bananabrooks3836 actually I think it is opposite for quite some time already. Any anodized thing looks automatically cheap, because everybody knows that chinese universal parts are anodized like these. When I see any anodizing now I automatically think "cheap shit" even if it maybe not.

[@vxlgsi]

The reason they are 2 piece is because its cheaper to make it this way. You can make 1000s of the steel part in different tooth counts and then make the centre section to suit different bike fitments. I like their stuff.

[@dirtygarageguy]

@vxlgsi apart from that's not true.

[@pauln6803]

Supersprox are shit. They somehow manage to weigh more than most OEM full steel sprockets... Which erm, kinda defeats the point.

[@inevespace]

do you have some source? Maybe some forum where people collect weight database?

[@pauln6803]

@@inevespace Personal experience buying one. Long time ago now, but disappointed have the oem in hand and feel the supersprox was heavier in hand. No complaints about quality (Renthal on the other hand...), just weight.

[@CodyT362]

Ay no don't blame the chalk thing on me - it's not my fault you can't keep organised 😉🤣 Couldn't that bending issue with the rivet clearance not be fixed by adding bosses that extend a bit from the bolt holes on the carrier side? Or would that put the chain out of alignment with the front sprocket?

[@dirtygarageguy]

1. yes, alignment would be an issue. 2. Calm down del.

[@mateuszkasza]

Lighter!? I weight those and those are actually heavier than normal steel one 😂those are just fancy ones

[@soulcatcher668]

I agree that the part does not fit, but if you are going to be replacing parts on your bike, you should be able to tell that it is not working. There is no way in hell anybody should have installed that and gone. "meh..... works for me" There is obvious interference and distortion. If you cannot see that at the time, you should not be working on your bike. I would also like to know the part number to see if it is even for that bike.

[@dirtygarageguy]

I doubt you would have noticed.

@@soulcatcher668 there are a lot of customers with lack of mechanical knowledge. I can easily imagine that half of people would not notice or ignore such thing.

[@soulcatcher668]

@@inevespace My point being, if you lack the mechanical knowledge, you should not be working on your bike alone. You should be doing it with someone who does. Should the part fit out of the box? Of course it should. This channel is more or less built on making fun of people on the internet trying to fix or modify motorcycles that do not know what they are doing. The person that installed this sprocket and did not notice that it did not fit, does not know what they are doing.

Their quality control seems to be a bit shit.

[@stevewalker2028]

Probably a labelling error. Still their fault of course.

[@dirtygarageguy]

Not a labeling error. The rivets shouldn't be on the same circle as the studs. Most sprocket carriers are full circle like this one, so the design was flawed from the beginning.
