These long stalk turn signals install using an 8 MM mounting stud. This offers a variety of mounting possibilities. See our eBay store for adapters to fit the front of many popular sport bikes. These also work great as rear turn signals, I mounted similar signals directly to my sub-frame with only minor modification. They feature rubber mounted studs so they don’t break easily when you accidentally knock them into something.
