So a chain did that to the sprocket?  Find that hard to believe.  :o

I'm sure it was more than 1 chain.

Nick, did he ride it in & you found it or was it acting up ???  If he were riding it around without a clue he should buy a lottery ticket because he's one lucky guy [laugh]

New rider, and relatively new bike to him.
He had no idea.

Bike has 27k miles on it, so no telling how many miles on this sprocket.
It's aluminum, so with poor care, one chain would be plenty to do that.
Chain is shagged too.

Rear tire is nearly new, so someone had the wheel out recently.

I've got a 9 tooth front that'd give him close to stock gearing to match!

Wow, even a new rider should think there's something wrong and have it checked out when the big starts reving up when the chain slips on the missing teeth. Either that or someone had that chain tightened up pretty good to to keep it from slipping.

I knew a guy that had an older Suzi and didn't know shit about chains. I kept telling him that his chain was too slack since I could hear it dragging on the swing arm. He refused to think anything was wrong. When I finally got him to look at it we found 4 broken teeth on the rear sprocket and 2 on the front. Chain had 6 tight spots and more than 10 broken links. I was amazed it hadn't seized up on him or broken.

I just don't get how they can get that busted up w/o causing something really bad to happen first.  ???

[laugh]

There are people who don't like to spend to much time/money maintaining their motorcycles so they don't get Ducatis and the like.  Thats one thing, but to take carelessness to this level is just, well, funny is the only word I can conjure up.

QuoteBack in 1981, 3 of us set off from England for a 2-week touring ride around mainland Europe. I was on my T150V Triumph Trident and the other 2 had Z1000 Kawasakis. Before departing, giving more thought to the fact that we would only be away from home for 2 weeks rather than the fact that we would be putting in some serious mileage, one of the guys decided that with a fairly worn rear drive chain, he would remove a link to provide more adjustment should he need it. 5 days and 2500 miles later in Athens (yes, Greece!) the photograph shows the result. As you can imagine, the last 300 miles or so, were only achieved by tightening the chain to provide friction drive with what was left of the sprocket. Indeed, such was the strain on the chain, that the rollers had flats worn on them by the time we arrived at our final holiday destination.

Really surprising how some guys will bring a bike to a shop with a simple problem instead of just fixing it at home.  If it were mine I'd just spend 10 minutes with a rat tail file deepening the grooves between the teeth and be good for another 27k.

WOW.....that is insane!  I broke 3 teeth on the rear and one on the front sprocket and it popped/slipped badly.  Quite noticeable at low speeds.  Had to be a pain in the ass to ride like that!

What type of bike is it?  What did he bring it in for in the first place?  I just don't understand how that would go un-noticed, even if he is a new rider.  I'll often go over the bike while I'm having a cigarette in the garage.  Just a quick 10 minutes or so to check oil level, chain tension and other things like that.  I just don't get it.

900SS, brought in for a full service.
Apparently not that happy with the work of the previous tech.

The rider is a young kid.
Not really looking to drag him down, I'm sure there's stuff that I've done (with things I know nothing about) that really isn't much different.

It took less than 300 miles to do this to my aluminum rear sprocket when the clip holding the front sprocket in place broke and it slid inward towards the engine.  That's the last aluminum sprocket I'll ever buy, and I check the front sprocket retaining clip more often now as well.

On the other hand, here is an aluminium sprocket that has done 5K, I'm happy to continue using it.

Most , not all aluminum sprockets do not last nearly as well as steel, I always prefer steel unless it is a race/track/never going to see many miles  bike

Care of the aluminum sprockets needs to be a priority, some lubes work well with aluminum.

I have a couple of saw blade sprockets around here but wark certainly wins the prize [bow_down]
He then looses said prize for sending male crotch shots..... where are the censors on this site? I mean really

Ah, I missed the aluminum part. Yeah, I could see it going to crap pretty quick then.

I think that banana hammock sprock is (was) steel... 

One of my buddys just got a bi-metal sprock called a super sprocket, I'm looking forward to seeing how many miles he gets out of it.

Also, an SV rider gf of mine had an overtight chain break on her whilst she was riding in Malibu.  Bent her countershaft and cracked the case on that side if I remember correctly.  Since, she's fixed the SV and got an S4R.  so she obviously learned something from it

My bad.  At least he understands about servicing the bike.

I just figure that most new riders spend the first month thinking "holy shit I'm moving! Oh god", and don't know how it's supposed to feel yet, so they can't tell anything is wrong.

I believe you're talking about the Stealth sprockets by Supersprox.  They have an Al center riveted to a steel outer.  Both Californina Cycleworks and Motowheels carry them. 

I have one on each of my bikes.  The Bandit Stealth sprocket has over 10,000 miles on it, and it looks fine, while the one on my Monster has only 5000 miles on it.

Yes.  But to be honest, I like them because of the aesthetics.
