A few months ago, the folks at MachineArtMoto sent us a sampling of their impressive products to review. MAM manufactures custom armor upgrades as well as various improved splash guards for BMW motorcycles. “Art” is very much a part of their product line, and the outstanding craftsmanship and fit reflect this aspect of the company’s name. But, don’t be fooled into thinking MAM’s upgrades are just pretty bolt-ons. Built for durability, these parts not only increase protection, but play a vital role in reducing maintenance. Installation is remarkably easy, too.

X-Head Cylinder Guards are thick, tough and wide to protect both the valve and spark plug covers of the boxer’s opposing cylinders. They’re molded from an impact-modified nylon polymer, with a high resistance to heat or chemicals, a design that’s far tougher than the stock magnesium cylinder covers they replace. In a crash, in addition to a good set of engine crash bars, the X-Head Cylinder Guards are likely to be your next line of defense to keep you going, or in the worst case, prevent expensive repairs.

The MudSling is an innovative guard that deflects tar, mud, water and rocks away from the rear monoshock and surrounding parts. It also reduces maintenance by preventing pitting of the swingarm and shock spring. Aside from general use, if you’re a hardcore off-roader, this is a bolt-on must-have. How well does it do the job? After 18,000 miles of severe rain, mud, gravel and road kill, it’s amazing how pristine my rear shock still looks. The Mudsling is so effective that cleaning the rear shock is a snap.

If you think of MachineArtMoto’s products as increased insurance against potential damage you can’t go wrong.  X-HEAD FIT: BMW '05-'09 GS, RT, S, R, ST, HP2, MegaMoto, and 2010 R1200R. MSRP: $169 MUDSLING FIT: BMW '05-09' hexhead models and 2010 R1200R; R1200R, standard suspension, all years; R1200R with ESA, all years. MSRP: $97 MachineArtMoto.com
