This is exactly the first thing that popped in my head. I'll stick with OEM products.

I have long, positive experience with OEM, and a serious aversion to being stranded many miles from home.

That said, I'm happy to learn from others' experience.

I bought a chinabelt for my suzuki burgman 400. I rode it 4000 miles, and it looked and measured OK when I sold it. I did warn the new owner about it, and gave him $100 off the purchase price because of it. So I didn't save a penny in the long run.

My advice: this is one of those cases where you get what you pay for. I was hypersensitive to variator noises and just waiting for a belt problem the whole time I had it installed. Spending an extra $50 on an OEM belt would have alleviated those worries.

The only thing that deserves a $50 China belt is a 50cc China bike.

Throw away whichever breaks first.

stuff from china is a case by case if you ask me.
tires from china can be very good. amazing actually.
last set of pirellis I bought for 600 lasted 25,000 miles
while my buddy was rolling on his 200 china tires for 60,000 miles. his girl hit somethin bad on the highway that took out the rim. so he bought new tires. they seriously looked like 60-70% tread remaining.

my current china tires have 5k on them. they have no perceivable wear yet.

Have to wait for an additional 4,000 miles before using it. There are far more scooterist in China them most nations so it make sense it should be OK. Will keep you all posted.

nope won't buy rubber products from china.
tires , belts, ect are key components to my scooter and safety.

Even on my cars and trucks or trailers I buy decent tires and not china stuff. blow outs or delam's are not pretty .
I buy tires for traction not mileage and change them out before the wear bars.

Actually, most belts are made in China. The way of the world these days. So its possible that the OEM belt and the Chinabelt are exactly the same. Here's my thinking:

Companies in China are motivated by profit. To create a completely fake belt that passes a cursory inspection, it would take more engineering cost than is available from the gross margins in a small total addressable market (thousand or less). If the belts were completely crap, then it would be obvious on inspection, even over the internet. If the belts were basically the same except a different fiber or rubber compound, then it would take competent engineering to make that change, which would be too costly to be worth the maybe 50k total revenue from the small run of fake belts. So, it's likely that the belts either came out the back door of the actual factory manufacturing the real belts, or were recovered from the QA-failed bin by an enterprising entrepreneur. Either way, the belt could work OK.

I've noticed that Chinabelts are available mostly for older models- like for the 2003-2006 Suzuki burgman 400, but not for the 2007-present suzuki burgman. Perhaps that's true for the MP3 as well- only the older style belt is available from Chinabelts.

You know a few years ago the US was ready to cut off Chinese tires from import because there were so many reported problems.

What did you get race tires? Most tire last a long time these days. My wife got 75,000 out of a set of OEM Michelin's.

Every tire has a wear code on the side that will let you know how long they should last.

If there is any doubt, then there is no doubt.

Use the original belt, and replace it when needed as specified in the factory service manual.

The belt is not a item to go bottom dollar on.

just purchase the china 500 belt for less than 24 shipped. for that price I will be the ginnie pig.

sorry if that offends someone. but my new piaggio belt has 5k on it. it started to get chatter 1k ago. I ride very hard. with lots of stop and go. only got 47mpg when I check a couple weeks ago.. if this cheap belt doesnt slip I will replace every 3500 or so.

Chattering is clutch not the belt. Sound like a sea lion, right? Few full throttle take offs usually fixes that.
Have never heard of belt slipping making noise on one of these.

Have fun getting the strands of belt out of the clutch, roller bearings and driven pulley seal.

Look up Quality Fade. That's the biggest problem with OEM parts made in China. The problem with fakes and knockoffs is another story. Your theory would make more sense if the scooter belt market was relatively small, like it is here, and not the gigantic worldwide market it is. When you talk to a Chinese supplier and he asks if you want belts that are X brand, or belts that say X brand, with a very big difference in price, you get a sense that there are a lot of belts of questionable provenance out there.

The big problem with breaking a cheap belt is not the $25 you are out, it's everything else the belt takes with it on it's way out. And your time and inconvenience, etc, ad nauseum...

I am fully aware of belt break consequences. had it happen to me when I purchase a blur 220i a couple hours from my home. bike had 6k on it. belt broke in the middle of nowhere florida. complete nite mare getting home. willing to take the risk for budget minded people. I am confident belt slip is sole reason belts break. new or well used. overheating belt is what makes them disintegrate. I know what slip feels like so not too worried here.

It is really hard for a belt to slip on a CVT system unless it is just worn out.

my china belt came in. but I think it is too small to try? will this belt even fit? wouldnt it be rubbing on crankshaft at idle? would it force it into lower gear sooner? I did checking and the belts range in length from 1036-1044. this one is only 1001.

Thanks guys. there is a china belt that is 1040 in length. thats the one I should have received. interested to see what seller says.

so with more research there was a shorter belt for the atlantic 500. 2001-2004.
there are two belts for those years. chassis PT00 VH00
827826 27.7 x 1011
832738 28 x 1036
found some info from italy that suggests 2001-2002 uses the shorter belt. curious exactly what changes in the variator? chassis number didnt change

in short though anyone who orders belt for their 400-500 from asia needs to be sure they are getting the 1040 belt and not the 1001.

The length of the crankcase hasn't changed, so it's hard to imagine they ever would have put in a belt that much shorter than the one they use today.

The belt you got the amazing deal on is about the same length as the one Kymco uses in a lot of their 300s or Suzuki uses on their Burgman 400, so the factory might have made a bunch of them too wide, and that's why they ended up on Ebay for the MP3. I think the width might be mismarked, because the Malossi belt for the MP3 is 28.8 x 1044 and I'm pretty sure the stock belt 849090 for the MP3 is pretty close to that. and this one looks to be as wide or wider. So they just compared it to a bunch of belts and figured out what it most closely matched. I've not seen that exact size listed on any application charts. On the other hand, it could be the right size for an ATV.

Penny wise and pound foolish for trying to saving a few coins on something as critical as the belt.

If there is any doubt, there is no doubt. Stick with original parts.

seller stepped up and sent the correct size. which is crazy to me. he had the 1040 size listed for 50 shipped. seems he should have just refunded the 23 I paid. wonder what these really cost over there?

so I got bored today and put this too short belt on the bike. it indeed fits just fine. bike drives just fine with it. even did speed tests against my buddies beo 500 and there were tiny losses in power due to the different gear ratio created. and I mean tiny. the only problem I found was belt was a bit noisy at idle. but I think its due to belt running deeper into rear pulley. I am running the malossi white spring on the clutch pulley so more pressure on the belt. I didnt care to try going back to stock spring. will post pics later on how deep it fit in back pulley.

but zero slip! and bike drove great with the belt.

You're paying a lot for those 849090s. They are usually within a couple euros of the 832738.

so the longer "beefy" belt arrived. it has been on the bike for about 200 miles.
the current piaggio belts are 1036 x 27. this china belt is 1040 x 28.7. the third dimension is contact width, piaggio is about 14mm. this china belt is 16mm.

initial impressions
above 3000 rpm. fabulous. transmits all the power with no feel of slipping
below 3000 rpm. unfortunately not great. the belt does not flex as easy as piaggio belt. so there is more vibration felt. and again I wonder if I should try going back to stock torsion spring.

the factory belt did measure 26.5 after ~5000 very hard miles. so initially I added 1.8mm of fuzzy washer thickness when installing this thicker belt. noticed the belt vibrations right away. so I started removing thickness. but there was no change felt. I think I left .6mm additional.

I was running just shy of 2mm washers with the piaggio belt. I am also wondering if belt would have smoothed back out by removing .5mm since belt wore thinner...

feelin the belt drama here.....

so I couldnt stand riding the bike after the first tankful on the big china belt (1040 x 28.7). just too much vibration added to the low speed operation. yesterday I reinstalled my used belt that was 26.6 thick. I removed some fuzzy washer thickness to compensate for the wear.

I officially suggest no one try these china belts. They dont work well. not worth the savings at all.

I would also be reluctant to try the mallosi belt for the 500 as well. It is very large belt at 1044 x 28.7. I would be afraid it would vibrate as well.

The bike is FAR more fun on the small belt. Not just smoother, but the power hits quicker on the small belt. bike is just more responsive.

above pic is 1001 x 26.9 belt. below is 1040 x 28.7

big china next to OEM 832738

It is really hard for a belt to slip on a CVT system unless it is just worn out.
This /\ /\

Belts on a CVT system don't slip unless worn out, or your shives/pulleys are worn out completely with ridges on them. Chatter is the clutch shuddering during move off due to incorrect cleaning of the pads, too much dust in the clutch housing, or the clutch springs are damaged. Very unwise to use a cheap Chinese belt but that's up to you. It can be dangerous. Many of my ex-customers had experience of cheap Chinese belts. They only did it once and paid a heavy price. However, good luck and hope it works out for you.
