The motorcycle sink faucet seems to no longer be in production, but may still be found used or through MC Advantages. This company is primarily a distributor of aftermarket motorcycle parts, but they also sell accessories and collectibles.
The designer motorcycle faucet is designed for two tap 4-inch sink faucet. It is getting more valuable as a collectible, so may be more expensive.
Overstock also has a listing for the designer motorcycle faucet, but it is listed as being "Out of Stock," as of August 2015. Customers may check out alternative motorcycle themed accessories, such as shower curtains, lamps and beer taps for the home bar.
