Belt and Pulley instead of sprocket and chain

Please pardon me if this topic has been discussed and my google foo was just not good enough to find the right place. Has any CBR125 owner converted from chain to belt? My wife and I are ready to purchase a 125r but we were hoping there was a kit for this project (like I did to her Honda 750 ten years ago). Thank you, in advance.

The Kawasaki KZ305 of the early to mid '80s was available with belt drive. The BMW F650 was also available with belt drive. Other than that, in recent times belt Harley is about the only manufacturer to adopt belt drive on any scale.

The idea is attractive. Belts are quiet and smooth. They are nearly maintenance free with a long life, but do have to be replaced on schedule. They looked a good option compared to the standard chain.

However since o-ring chains arrived on the scene the most of the disadvantages of the chain have been overcome. An o-ring chain life is as good as a belt with minimal maintenance compared to a standard chain.
You beat me to it Michael. It was called the GPz 305 over here, and it was quite a good little bike in it's day. :D

Why would you need a belt drive? Chains have been used foor decades without issues. i'm lost here
You don't have to keep lubricating the bloody things. No mess either. ;)
The cbr has 23hp,

The cbr has an incredibly over engineered heavy 520 oring chain. (that why I dont run one because theres an easy hp gain)

bet even the noobest of noobs that neglect their bikes in the worst fashion could not break it in 20,000 miles.
26 bhp at the crank, which is what all manufacturers quote. A belt drive would be a bonus for me. No maintenance. ;)
