don't be tempted by the pretty gold colour....sprocket - SV650.org

As some will know the (new to me) Aprilia pegaso has been going through some checking and servicing, the chain and sprockets needed changing and were done as promptly as I could get them, the rear sprocket was a Renthal gold "hard anodised" one, I've used alloy sprokets before on small trials bikes but never on anything bigger, I won't be doing so after seeing the state of this one.

And just in case you can't see how badly the profile has worn, here's a new steel one below for comparison.

you have been warned.....

no no, you have it wrong those are the new anti-wheelie design.

I don't think you're supposed to use a sawmill blade for a sprocket. How long had that been on the bike?

21-06-12, 05:45 AM

Holy crap, that's wore the hell out of that.

I've never used the alloy ones but I've always wondered they can't possibly be as strong /durable.

I've no idea, but it wasn't OEM and even badly looked after the originals should have lasted 12,000 or so (conservatively), then it could only have been on for a maximum of 6,000 miles at most by my reckoning.

I'm surprised you got any drive out of that....

On a side note, you cannot assume that the C&S was previously replaced because of wear, on the tarty Street Triple forum people change out C&S's regardless of age or wear just because they want a shiny gold one!

anything is possible, but as the person I bought it from was the second owner and had only done 4,000 miles in the first year (just commuting) and 246 miles in the second that he owned it (spend most of the year parked up as he moved and started taking the train to work), I doubt he's the type to "fashion" change things.

Oh dear that looks dodgy, how did the chain not jump off those gums. What do you recommend as a good make Rictus?

rictus01 · 21-06-12, 08:07 AM

the chain didn't jump because it had plenty of adjustment left in it and the chain was still fairly good, I "bow stringed" a bit, not something I'd normally do or recommend (but I knew I was changing the whole lot anyway), but it did the job the steel chain dug into the alloy and it got tightened every other day.

just the standard steel JT sprocket will do, or if you're really flush and want the flash look get the stealth type ones (alloy centres and steel tooth ring).

Cheers Mark.
