BikerShield
BikerShield Motorcycle Protection Barrier provides safe rider containment and redirection through the combination of spring mounting brackets and lightweight, corrugated panels. The spring brackets attach directly to the guardrail beam mid-span between posts and absorb the impact energy of the sliding rider. The BikerShield mounting bracket position is an important design consideration as vertical alignment with the face of the guardrail beam reduces the potential for rider snagging.

Crash tested in accordance with EN 1317-8.
Innovative Design
Connects directly to the rear of the guardrail beam.
Leading Safety
Shields a dismounted sliding motorcycle rider from contacting the guardrail posts.

Frequently Asked Questions
What are the risks of guardrail barriers to motorcycle riders?
Guardrail barriers can present risks to motorcyclists, primarily because riders are unprotected and can collide directly with the barrier structure during a crash. Exposed steel posts can present a snagging risk to a sliding, dismounted rider.
How does BikerShield work?
BikerShield provides safe rider containment and redirection through the combination of spring mounting brackets and lightweight, corrugated panels. The spring brackets attach directly to the guardrail beam mid-span between posts and absorbs the impact energy of the sliding rider.
What is the benefit of securing the BikerShield mounting bracket to the rear of the guardrail beam?
Securing the mounting bracket to the rear of the guardrail beam ensures the face of the BikerShield panel and guardrail beam are always vertically aligned regardless of guardrail post type and any lateral offset between the face of guardrail and the post. This is an important design consideration as vertical alignment reduces the potential for motorcyclist rider snagging.
What is the crash test standard for the evaluation of a motorcycle protection rail system?
European Standard EN 1317-8 specifies performance classes and test methods for systems designed to reduce injury severity to motorcyclists who collide with safety barriers. Tests involve a dummy sliding into the barrier at 60 km/h. The system’s performance is rated using the Acceleration Severity Index (ASI) and head and body injury criteria
Does the attachment of BikerShield affect the crashworthiness of the guardrail barrier system?
Acceptance of motorcycle protection rail systems by Australian state road agencies requires a vehicle crash test demonstrating that the attachment of the motorcycle barrier does not adversely affect safe vehicle containment and redirection. Vehicle impact performance of BikerShield was undertaken when attached to RamShield W-Beam and performed with an 1100 kg passenger vehicle travelling at 100 km/h and 25 degrees as nominated by MASH.
What guardrail barriers are suitable for the attachment of BikerShield?
BikerShield is suitable for attachment to all RamShield guardrail variants including RamShield W-Beam, RamShield Median W-Beam, RamShield Low Deflection and RamShield High Containment.
Can I retrofit an existing guardrail barrier with BikerShield?
Yes. Existing public domain and RamShield guardrail systems may be upgraded with BikerShield motorcycle protection rail system. Since BikerShield attaches directly to the guardrail beam there is no disturbance of the existing guardrail post.
How do I terminate the ends of the BikerShield system?
A specially designed bullnose is used to terminate the ends of the BikerShield motorcycle protection rail system and shield sharp edges.
Can the BikerShield motorcycle protection rail system be installed within the guardrail end terminal section?
No. The BikerShield motorcycle protection rail system should be terminated before the guardrail end terminal. The guardrail end terminal is designed to absorb or dissipate vehicle impact energy in an end-on collision. The attachment of a motorcycle protection rail system in this region may affect the function of the guardrail end terminal.
Can BikerShield be installed on curved roadways?
Yes. The BikerShield panel has a thickness of just 1.5 mm facilitating field curving to suit site requirements.
Can BikerShield be attached to wire rope safety barriers?
No. The BikerShield motorcycle protection rail system can only be installed on guardrail barriers.
