Chain and Gear for Scooter Motor

[robosang]

Anyone know where can I get the chain and gear for 350W Scooter motor?

The teeth of gear seem to be compatible with normal motorcycle chain, but it is really compatible?

According to Cytron website, it stated "11 teeth sprocket (#25 chain size)", if your bicycle chain is also #25 size,
it should be compatible, because it is the imperial standard that globally and commonly used.
Special hardware shop selling belts, pulleys, sprockets will carry the stocks, for example: http://www.bangkok.com.my

Note: You mention the "Gear" is actually is called "Sprocket"
