Each weight is 290 grams
*Though Aprilia will sell these to you each, we STRONGLY recommend you purchase in pairs becuase there are often slight, but noticable color variations from production batch to production batch. If you order two bar ends at the same time, you're guaranteed a matching set.
**Additionally: Aprilia does a reasonably good job of packaging these bar ends for their 5,600 mile journey to the United States (double layer bubble wrap) but you should expect some cosmetic imperfections (like the one seen in the 2nd detail image).
The retainer bolt for this bar end is part number 2B002580
