The X-Head DOHC is designed to protect more of the cylinder head surface than any other guard in the event of a fall. Even if it gets away from you in the driveway, the inertia will cause the bike to roll onto the face of the cover before the bike settles down on the bottom of the cylinder. When off-road riding, X-Heads work together with crash bars to prevent damage from rocks that can get past the bars. Behind the tough nylon shell is a thick rubber liner that helps absorb impact force against the cylinder.
Included are stainless steel bolts with Nyloc threadlock patches so they stay tight. X-Head DOHC protects while letting just enough of the new head shape to show through. They fit with the following crash bars: BMW OEM; Adventure Designs BMW crash bar extensions; Touratech; Hepco Becker; SW Motech; ALT Rider. Does not fit Z-Tecknik bars. The rule of thumb is: if your bars fit with BMW's OEM cylinder guards, they will fit with X-Head DOHC.
X-Head DOHC fits all Dual Overhead Cam engines, including the 2014 R1200R and R nineT.
Fit and compatibility with BMW or aftermarket crash bars with X-Heads may vary, depending on their manufacturing size accuracy and any running changes the manufacturers may make over time.
Installation with crash bars: To install X-Heads on R1200 GS/A already fitted with crash bars, they will have to be removed to provide enough working room for X-Head installation. It is recommended that removal and re-fitting be done by a qualified BMW technician if there is any concern about the procedure.
