Question about 2004 Derbi Senda SM 125 4T
Ok lat time im asking about this scooter its a x-treme scooter xm155 yes a chinnesse scooter its brand new has 140 miles on it my concern is when it gets past 40 miles per hour you hear a kind of like almost like a bearing sound from a wheel noise seems you can feel it under the seat like a bad bearing sound and when you let off the gas the sound goes away is this normal is this they way the feel at higher rpms or do i have a problem any ideas? and 2nd did i make a big mistake buying a chineese scooter? also it says i need to change the gear oil at 200 miles could that sound be from not changing yet from factory gear oil and it will go away? or is it normal in break in period many thanks!!!!
YOU DID NOT MAKE A MISTAKE!!! Xtreme is a good bike. Comes with a 2 year parts and labor warranty. Sold them since 1999 and never had any major problems. Customer bought a Polaris and an Xtreme atv. The Xtreme out lasted the Polaris. Fact. Adjust chain loose not tight. Most likely it is too tight. Check chain guard and where chain rides. We have seen the chain rub the frame, but that depends on the bike. Also if the exhaust is close to the frame and touching the frame, that will give you noise.

Yes, you made a mistake buying a cheap poorly made Chinese scooter. But that being said, you say it is brand new with only 140 miles on it. Is it not still under warranty? Take it back for repair where you bought it, or preferably a refund if possible. The sound you are hearing may very well be normal for this scooter. You may be hearing chain noise. Make sure the chain tension is adjusted according to the owner's manual. If the chain is too tight it will cause noise and wear. It is critical the chain be correctly adjusted. Go ahead and change the gear oil to eliminate that as a possibility. Also look closely at the rear wheel and make sure it is aligned properly and not cocked. It must be dead center of the swing arm.

If the bike has knobby type (bumpy tread) they do make noise.Just be sure they have the correct air pressure in them.
Try to support the bike so you can manually spin the wheels like if the bike had a center stand.Feel while turning, to see if the wheels feel to tight or loose.And try to feel any play in the wheels. Or hear any stange noise.
While your are at it go ahead a drain the oil and change it with a good quality oil. The bike should have come with a book to tell you what type oil it wants.Dont be afraid to change the oil more than it is suppost to be.They dont hold that much oil and the shifting of the gears will generate alot of break in metal dust that needs to come out of the engine.
To say if you made a mistake in buying the bike remains to be seen because their is no history of the Chinese bikes in this country.
If I could ride the bike I could give you a better opinion.
Another thing you could do is, while riding the bike with it makeing the sound,pull in the clutch and put it in neutral.Is the feeling gone?
This can help to be sure the noise is not engine generated.
