It also didn't really bother me.
review Newtons Laws... R90 is motor torque, shaft
mass is inconsequential...

Techincally you are supposed to lube the chain every 500 miles.
Total loss oil system: Route the breather tube down to the
chain, viola! continuous oiling...

Then your chain doesn't get rusty like those
on the ninja-like bike all the kids ride in the
college towns...

He's talking about torque, not mass.

I'm not a mathmetician.

It seems to me though that a spinning driveshaft, assuming it's strong enough for the job, will deliver the torque whether it weighs 1 lb or 2, whatever its mass.

It will also mass the same whether spinning or not.

Two different animals.

as long as 1st gear is tall enough thell last...but on heavier bikes they wear out and you could blow one in an hour if you badly abused it...i have normally worn em out on my wings over the years and also blew a belt on the hd...but that taught me to learn how to set a belt and how to treat it to last.

Red face Belt

Shaft works fine but is heavy and expensive to repair.
You can't change gearing cheaply or usually at all.
Belt works fine but can pick up little stones & break.
Belt is a PITA to change since you have to pull the swingarm.

I have one of each... there is a different feel from one to the other but both ride very well... I think I'm liking the belt more and more though... I just like the feel a little better... :-)

All my past bikes were chain drive, but my current ride is shaft driven and I really do like it. I've not had any handling issues, but I've gotta say, I don't miss the maintenance. From that point of view, a belt is similar to the old chain drives......more maintenance then a shaft.

Not much to do with a belt.
Just make sure it's adjusted properly.

I've noticed some use a shaft setup instead of a belt, is there any benefit, downside to doing so????


Thanks.



Figure i'v egot lots of time to reasearch....20+ years before the kids are moved out and the wife will let me get one, lol. So i'll have lots of knowledge by then.
This was the OP's post which was 6 years ago...

Wonder if this thread will last another 14, if he has decided, of if he needs more opinions\ research...

My point exactly.......don't have to do that on a shaft drive.

No,you don't but you have a universal,a driveshaft, & a ring & pinion gear.
When it breaks it costs a LOT of $$$$ to fix.

A belt is cheaper.
