Have you performed Gliders bulb trick?
The bulb trick should have been your next step. I am just trying to help but you can keep changing circuit breakers until the factory runs out of them and you may not find your problem. Your problem may not even be the circuit breaker. That was the reason for the bulb trick test.
If the bike quits and the bulb is still lit,,,Bingo. You know it is Not the breaker. One clever test and you know everything up to that point is Good. If the Bulb goes out the same time the bike quits, then change the CB for an Equal rated Maxi fuse. If the Maxi fuse also blows, you WILL need a factory schematic to troubleshoot (not shot-gun) the reason why the fuse blew. Upload the schematic of your bike and we will walk you through your problem.
