The fitment is....not good. They fit, they work, they do their job. However, the shape is completely wrong and they sit at the back part of the indention where the mirrors go. These were obviously not specifically made to fit the shape of the indention for this model specifically. If you need something to just do the job on your trackbike, they're fine. If you really care about the fit and finish of your bike, I wouldn't use these.
This is a scenario where actual product fitment photos would have saved me some money.
