The ball peen hammer on a bike (commonly hung from the engine mounts on V-twin) was known as a "traffic cop" and back in the day when people on the road cut you off, you used it to hit their vehicle. I would imagine you would givew your bike a really old school look (to those who know what it means) but you could also be looking at alot of trouble. Not just from john law who see's you riding by but also from the FOD (foreign object damage). What if that thing rattles out and hits your chain? Thats bad news dude. But opinions are like A$$holes, everyobdy's got one. Good luck!
