When chasing grip on loose surfaces, the XRAY XB4 2017 benefits from the XRAY 361265 Medium Composite Chassis Side Guards. The medium hardness composite provides an extra degree of compliance while keeping the chassis interior protected from stones and muck.
This medium-hardness material is softer than the standard kit guards, which increases chassis flex and can improve turn-in on low-traction tracks. The guards fit precisely to maintain a sealed chassis and offer solid defence from side blows during close racing.
