Just wish they would've made it adjustable

I agree with the previous comment. Looks cool. But it does rub against the heat shield. At first I thought the heat shield was slightly pushing down on the arm. I was able to move the heat shield slightly back enough to fix the issue. You definitely lose leverage and really can't smash on the rear brake if needed. Takes a lot of pressure to activate the ABS with this arm. I assume due to the aggressive angle of the arm. I was eventually able to smash down on the brake. But it took some time.


Does not fit but looks cool

Does not fit Harley Touring. Rubs on the heat shield. I called Pro One, they said sometimes it does that and suggested that i cut the heat-shield where it touches. I decided to grind down the inner edge of the arm instead. Got the clearance I needed, but the arm is so short, it makes it very difficult to mash down hard enough to stop. I rode with it for about a week now. Feels very unsafe not being able to stop quickly. The leverage is not there, feels like you get half the stopping power as usual.
