Engine Guards, Frame Sliders, and Motorcycle Protection
The engine guard is the tubular bar that runs along the sides of the motorcycle and absorbs impact instead of the crankcase, tank, and fairing when the bike goes down. Together with frame sliders, radiator protection grilles, skid plates, and heat shields, it comprises everything needed to prevent a standstill fall from turning into a bill for hundreds of euros. The catalog features 207 active items, largely from RD Moto and Kappa Moto, almost all specific to model and year.
Engine Guard, Frame Sliders, and Motorcycle Protections: Guide, Tips, and FAQs
Engine Guard, Sliders, or Both?
The engine guard is a tubular structure that wraps around the engine and distributes impact to the frame: it offers more protection and is the choice for travelers and off-road riders. Frame sliders are nylon or aluminum cylinders bolted to specific points on the frame: they are more discreet and more economical, and they keep the bike raised just enough to save the fairing and levers. On road sportbikes, they are the most common solution.
Radiator Protections
The radiator grille is made of stainless steel or aluminum and serves to stop stones that, at highway speeds, can puncture the fins and immobilize the motorcycle. It is a model-specific part: sizes are not interchangeable.
Installation
Almost all engine guards attach to existing frame anchor points provided by the manufacturer, often replacing existing screws with longer ones supplied in the kit. The manufacturer always indicates the target model and year: you buy based on the vehicle's year, not just the name.
Frequently Asked Questions
Is the engine guard suitable for my motorcycle?
Only if the product sheet indicates your model and year. These parts attach to frame points that vary from one series to another: an engine guard from a different year will not fit.
Do frame sliders damage the fairing in a fall?
A correctly mounted slider works before the fairing touches. If it is mounted on brackets that are too protruding or too short, it can act as a lever: the manufacturer's instructions must be followed to the letter.
What is the difference between a skid plate and an engine guard?
A skid plate is a plate that protects the oil pan from stones from underneath, typical of adventure bikes. An engine guard protects the sides in case of a fall. They perform two different jobs and are often mounted together.
Does the radiator grille reduce cooling?
Grilles made for the purpose have a mesh designed not to obstruct airflow. A generic, too-dense mesh, however, can raise temperatures: a model-specific part is better.
Are special tools required for installation?
In most cases, hex wrenches and a torque wrench are sufficient to respect the indicated tightening torques. On some motorcycles, part of the fairing needs to be removed.
What is a carbon fiber heat shield?
It is a shield applied near the exhaust terminal to protect the fairing, bags, and leg from heat. The catalog includes Arrow models specific to motorcycles.
