Just reading up on BMWs latest scooters. Its a 647cc parallel twin.
Seems to make sense to me. Curious, why a typical, modern motorcycle wouldn't benefit from this?
Cost? Complexity?

That cast chain case probably weighs a fair bit, and a lot of that weight is unsprung, too.
Doesn't look any beefier than my 929's swingarm,LOL

That looks like it would make chain inspection one major pain.
Great idea lot less complex and lighter than a drive shaft with universals and a ring and pinion.

PM if you have one for sale.
I know that a motorcycle manufacturer somewhere actually sold a bike this way, many years ago. I can't remember exactly who or when, though.
Edit: What the ... apparently Harley did this as recently as 1984.

Yamaha had a 920cc v twin that had an enclosed chain, although I don't think it was oil bathed.

On a scooter yeah, on a sport bike nah. The weight and movement of the oil would mess with stability IMO. Not to mention that a chain is a lot more likely to snap/fail under 100-200hp acceleration then on a scooter and id hate to see the repair bill if it did inside the swingarm.
I plan on leaving this world the same way i came in...... Bloody and screaming.
It looks like the swing arm pivot is the same as the sprocket centre line unlike most bikes, therefore the chain slack will remain constant with suspension movement allowing it to be adjusted relatively snug.
If your 200 hp sports bike breaks its chain it will likely wad up and do some serious damage to your engine rather than simply fall off.

It was oem for a few bikes many years ago.It's mostly about the ugly chaincase i think.

You would have to use a non-oring chain for this to work best.
I guess it would help with keeping the wear down on the sporckets...seems like you are adding more weight and complexity with this crap though.
Is it that hard to just maintain your chain?

It's BMW. They over engineer almost everything. Though husqavarnas division is probably manufacturing this it might actually be dependable !!! LolOriginally Posted by frekeyguy

This, plus the fact that the rear arm pivot point is the output shaft means the chain can be sealed completely (the chain cover would just require o-rings around the output shaft and rear axle).
There is no planet B.
Less efficient, heavier, more costly.
