The product is a 2016 Yamaha YZF R1 R1M engine motor with only 3,000 miles! This street motorcycle engine was made by Yamaha in the United States and is designed for gasoline fuel only. NOTE: DOES NOT INCLUDE THE CYLINDER HEAD. Originally bought to replace engine my R1, but shop was able to repair the engine already on the bike so I don’t need it! Motivated to sell, with reasonable offers!
