Yes, a BMX chain 1/2 - 1/8 is the size. I use a BMX YBN(Yaban) half-link chain. It's light, and the most durable I have encountered. Be warned, this chain enjoys breaking your chain breakers. I used a motorcycle chain breaker, and it also got broken. A 415 chain is commonly used in go-karts, tractors and some motorcycles. You can easily get 415 chain in motorcycle spare parts shop and tractor parts shop.
