These cylinder guards are designed to cover 85% of the face of the head to protect, not only the bottom/front initial impact area, but also the mid part of the cylinder head. Even in a stationary drop, inertia can cause a bike to roll partially onto the face of the head before it settles down.

For off-road riding the X-Heads complement BMW’s crash bars to protect heads from rocks and strike angles onto terrain that can get past the bars. The X-Heads are styled to complement the new models and are the best choice for riders who do not like the look of crash bars.

The X-Heads design benefits from a SuperTough nylon polymer successfully proven in use with the X-Head models.
With its blend of high impact strength, temperature and UV stabilization, the injection moulded shell is designed to be slightly ductile in impact to prevent breakage. On the inside of the shell is a thick thermoplastic rubber liner that rests against the face of the cylinder to aid in dissipating impact force while preventing hard contact.

The X-Heads are designed to protect both the valve and spark plug covers. If a bike is dropped at speed, any material will wear at the point of contact, but nylon will not break or puncture. Even a driveway drop will cause a bike to roll onto the face of the valve cover and X-Head’s wide shape helps to protect more area than other head covers.
