Will this sprocket fit both my 1998 and 2015 Harley?

Yes — the included hub adapter ring accommodates both 1984-1999 and 2000-2022 hub styles, so one sprocket works on either bike.

Why is the aluminum carrier lighter than steel?

Aluminum is inherently 70% lighter by weight while the riveted carbon steel tooth ring maintains strength and durability for chain drive.

Is this sprocket street-legal?

Yes. This is a direct replacement sprocket for V-twin motorcycles and street use.

How durable is the black finish?

The anodized black carrier and zinc-passivated sprocket with clear coat provide corrosion resistance for long-term outdoor use.
