I think @silva is the person to ask.Motorcycle chains seem to be heavy duty and rubust, so can I use a Motorcycle chain on my single speed bicycle. The 415 size Motorcycle chain has the same 1/2 pitch as a bicycle chain and is a narrower Motorcycle chain. The roller bearings are 7.75mm diameter.

Another consideration is that I would need to buy a Motorcycle chain with the correct amount of links including a split link, so I wouldn't need to get a Motorcycle chain splitter.
These are 415 size Motorcycle chains:

If you have a proper track bike, does chain stretch matter - can't you just move the wheel back to take up the slack?I'm using a proper Dolan track bike on my training rollers, the cheap single speed chains stretch quickly.
Usually, though very powerful legs and very poor cycling technique can destroy chains. I've seen it done, after warning the rider in question that unless he changed the way that he rode, he would kill his chain. He didn't, and he did!Strength is of little importance considering just leg power.
I searched alot for a motorcycle sprocket as chainring, but I couldn't find any for my configuration.The motorcycle sprockets are considerably thicker than a bicycle sprocket / chainring mind.

I asked JT sprockets. They had 1 candidate for my gear:I think it would be an engineering job to modify one, you'd want a rear sprocket as the front chainring but modifying a motorcycle front sprocket to fit a bicycle rear wheel would require an adaptor and a lot of work!.
Saying all that you'd be hard pressed to wear them out. JT sprockets are very hard wearing.
The BCD is 130 mm, but only 4 mount holes, while mine is 5.Thank you for your enquiry.
JT produce final drive sprockets for motorcycle and ATV applications, and we do not offer products for bicycle fitments. Our steel rear sprockets are made from C49 high carbon steel.
We produce one sprocket that matches your 130mm bolt hole PCD, 420 chain size and 47 tooth count, part number JTR215. Please follow the link below for more information.

We do not offer a custom sprocket service and are unable to produce "one off" sprockets to suit your requirements.
I hope that this helps and thank you for your interest in JT.
