Jos is looking for a dual sport.

What's the special feature that "SOLD" you and Jos on it?
Looks VERY trick...
the teeth are off set and the grooves in the sprocket are there to clean the drive system, dirt is the enemy of chains. The sprocket itself is cut out of stainless steel and then coated in nickel, its lighter than a standard steel sprocket but still stronger than an aluminum. Substantially on both accounts.
 
I am curious to see if the zig zag of the sprocket will cause the chain to wear faster. Seems all the back and forth of the teeth will put strain on the chain:noidea:
All the research I did on it said that it wears the sprocket faster but the chain lives longer since it cleans itself as it rotates.
