Thumbs up Dayco Timing Belts - Has Anyone Tried Them ?

I bought a set of Dayco Timing Belts for my SS, made in Italy . The seller claims they meet or exceed Ducati specs. Has anyone else tried them or am I the first ?

I know of the Bucci belts and cali cycleworks but not Dayco. Are the teeth more squared than round? if so they may be who makes the Bucci belts.

I am not one to experiment with things that can blow up my bikes, especially when you can find belts that are known to work for short money.

Why would you ever risk catastrophic engine failure?

Looks like you bought urself a paperweight imo.

When in doubt, lean more...

I'm not real worried or I wouldn't have bought them without checking with the Brain Trust here first. Dayco is a major belt manufacturer, not some fly by night outfit. The belts are specific timing belts, not just a toothed belt that will fit. The teeth are rounded like Ducati belts, not squared off, so not Bucci, I guess. I assumed I'd receive a massive " Oh No, You Di' Int !" When I brought it up. I've never done my crank plug either so I guess I'm riding a time bomb one way or the other. Just something I've been curious about ever since I bought a Ducati. Only two suppliers for a wear item like this , backed by the threat of imminent destruction if I dare challenge the status quo ? Seems only natural to me that I would be the one to break the mold. Here, hold my beer while I put these belts on !

I just replaced the belts on the Misses S2R 800 and bought the OEM belts locally from a OEM dealer and they were $74.99 each and tax. I guess there is some money to be saved, but I can't buy the parts and repair the 803 for $106.00 so I'm gonna play it safe and use the OEM belts. I do hope these belts work good for you though.

Me too. I can only imagine all the shit I'll have to take when I come back here and tell you both belts blew out the first time I rode it. I can hear the "toljasoes" scratching at my door already.

If the belts were designed right and made well there should be no issues. The problem is there is not enough of a sample tested to know if either are true. So the Ducati community should thank you for being a test pilot and do let us know how they hold up long term.

I am cautious on selling parts with dire consequences as the customer will be pointing the finger at me if something goes wrong and I make next to nothing selling belts so I have no interest is experimenting on customers bikes. I waited 5 years after the cali cycleworks belts came out before offering them to my customers, in that time I watched for problems on the web and installed many sets customers brought me to install (their liability). I was likewise going to sell the Bucci belts and had some on the shelf when a customers 916 running Bucci belts shed a tooth, that killed my confidence for a bit.

Also keep in mind construction (materials) in the belt can make a difference in tension, I find often the cali cycleworks belts do not have the same pitch as oem so expect a different tension if using a Hz measurement. Dayco could be similar as were the old OEM non-kevlar belts.

I've always used OEM. Do I read between the lines the newer OEM belts are Kevlar and the old were not. Does this change service intervals?

officially or real world?
