Crash bars are heavy-duty metal bars that are installed on a motorcycle, ATV or other off-road vehicle to protect it from damage in case of an accident. These bars are designed to absorb impact and prevent the vehicle's fragile components such as lights, mirrors, and windscreen from being damaged during a crash. Crash bars also provide additional protection for the rider by deflecting some of the force of an impact away from their body. Overall, they help increase the safety and durability of off-road vehicles in challenging conditions.
