I used an RK O-Ring Chain.
RK Chains are one of the Best quality parts you can use for your replacement Chain.
They are Sealed O-Ring chains, and use high-carbon alloy steel.
The RK 520MO is a good choice for durability and reliable performance.
I don't think that the torque produced by this little 150cc engine will put an excessive load onto the chain. I expect a very long life for this chain.
It was about $100-$120Aud from Western Motorcycles - Sydney AU.
And for the Cogs...
I got 2x Quatlity Steel 'JT' Cogs - JOMTHAI ASAHI - Made In Japan.
The front one 15T from Tyga Performance for about $6Aud.
The Rear from Western Motorcycles - Sydney for $48Aud.
