X-Head_LC cylinder guards
X-Head_LC cylinder guards are designed to cover 80% 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, X-Head_LC complement BMW’s crash bars to protect heads from rocks and strike angles onto terrain that can get past the bars. X-Head_LC are styled to complement the the Liquid-Cooled models & are the best choice for riders who do not like the look of crash bars, especially on an RT.
The X-Head_LC design benefits from a "SuperTough" nylon polymer successfully proven in use with the X-Head DOHC and SOHC models.
With its blend of high impact strength, temperature and UV stabilization, the injection molded 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. Each side mounts via 2 stainless steel M5 T25 Torx Head fasteners and one existing T50 bolt.
We’ve received feedback from a couple of customers about variations in mounting clearance between the X-Head and their 2015 GS and ADV crash bars. In one case there was sufficient clearance with the bar on the right side, but the rubber pad on the left side touched the X-Head. In a second case the customer reported that the crash bars on both sides of his GS could not be re-installed after X-Heads were mounted.
There is a solution for fitting X-Heads to bikes with tight clearance â€" shims in the form of tubular spacers or thick washers placed behind each of the crash bar mounting flanges that bolt to the engine. On bikes needing them, shims will offset the bars slightly to the outside to restore adequate clearance. Adding them will not affect the bars’ function in any way. Even if the rubber pads on the bars end up touching the X-Head slightly after remounting the bars, it will not affect X- Head integrity as they are designed to withstand compressive force in case of a drop.
