Well let’s look at high torque Harleys or the big V twin customs ( think 124 cu inch mill) they run a belt at final drive they can wheel spin a 320kg bike and after initial running in need only one readjustment to remove slack in the final belt drive.I too think the fancy tail it amazing. Dick Degraw uses something similar on his Rhino. I was just giving my humble opinion as to why they are using a belt drive instead of a gear box.
The belt isn’t as a good power transmitter in my opinion. Most people think those belts isolate the engine pulses like the rubber bumper in the gear box they don’t at all. They are called a poly chain for a reason.
I used to own an older Harley where we had a belt drive as the primary from the crank to the gearbox …the belts did seem very bullet proof, BMW on some of the smaller bikes powered by Rotax are using belt in final drive
The rotax gearbox can wear and often does removing it saves weight, complexity with the Cush drive slipper clutch and so on, a belt on final seems like a great solution RAF use it to we don’t see many reported issues with it, but then here locally we don’t have many RAF’s flying
