I didnt add that arrow. The power delivery goes the other way.
thank you! *looking up ring and pinion right now*

Well you can lube a belt if you want, but I suspect the results would be much like putting armor-all on the tread...in other words...very BAD...

You do have to adjust belt tension on occasion, but not all that often. Typically you'll remove the rear wheel to change the tire more often than you would need to adjust belt tension. Remounting it requires re-tensioning the belt, so....

Yep - Concours, FJR, VFR, most BMWs, the Gold Wing, many metric cruisers, etc...

Nothing wrong with shaft drive at all. It is very good for what it is intended to be - a stable, near-zero maintenance drive design.

Belts are great too - to a point. After a certain amount of power, they become more a liability than anything else. They also make such things as changing sprockets a bit more difficult.

Chain? Also great - but require more maintenance than most mile-eaters want to deal with.

I never took great care of the chains on my sport bike and never could grasp the idea of cleaning it. SHame on me I know, Patrick would always run his mouth about it when I would have to buy new sprockets time and time again along with chains.

I never hear about these in the sportbike world so I'm clueless as to their advantages and disadvantages.
Does anyone have any info on the maintenance and power output on belt and shaft drives?

If you've owned a bike with one of these kinds of drives, what do you think about it?

Any info would be appreciated, thanks ya'll!
Well, I concede the chain is better for all-out performance, that's what a sport bike or an MX should have. But the shaft rules supreme for the all around motorcycle.

Maintenance free, durable, and so quiet--it makes the chain appear old-fashioned.

2009 MotoGuzzi MGS 01CORSAhtm

Shaft driven, lots of torque.

The power is lost in a variety of ways. You lose some with every change in power direction and with a shaft, you've got at least two changes in direction. You also have the power necessary to move the shaft itself - that's a big chunk of metal.

Typical shaft drive, you have a ring and pinion at both ends allowing for a 90 degree direction change.
