Nylon Motorcycle Guard Bar Protection Block 90 x 50 x 50mm Bumper

This nylon motorcycle guard bar protection block is a practical add-on for riders who want a replaceable bumper point on their engine bars. It is designed to bolt onto compatible guard bars and act as a contact surface during a fall or slow tip-over. The block measures 90 x 50 x 50mm and is made from nylon, a material chosen for its resistance to wear and impact. It comes with the mounting hardware required to attach it: four M5 x 25 stainless steel screws, four M5 stainless steel locknuts (4mm), and one hexagonal wrench. Available in black, red, or blue, it allows you to match or subtly accent your motorcycle's existing colour scheme. The simple single-piece design has no moving parts, so there is nothing to adjust once fitted. This makes it a straightforward accessory for riders looking to protect their guard bars without a complex installation.

Features and Construction

The protection block is built around a solid nylon body with pre-formed mounting points. It is supplied with stainless steel fasteners and a hex wrench, so the basic fitting components are included. The design is intentionally simple, focusing on a durable contact surface rather than complex mechanics.

Material and Build

The block is made from nylon, a tough engineering plastic that resists abrasion and repeated contact. Unlike metal bumpers that can scratch or transfer impact directly to the bar, nylon offers a slightly yielding surface that can absorb some energy before deforming. It is a single-piece moulding with no seams or joints, reducing the chance of weak points. The included M5 x 25 screws and M5 locknuts are stainless steel, which helps them withstand weather exposure better than plain steel. The supplied hexagonal wrench matches the fastener heads for a secure tighten.

Size and Practical Fit

At 90 x 50 x 50mm, the block provides a substantial contact area without being overly bulky on the bar. The 50mm width and height give it enough face to meet the ground or an obstacle before the bar itself does. The M5 mounting hardware suits typical guard bar brackets that accept 5mm bolts. Because the block is rigid, it should be mounted on a flat or suitably shaped section of the bar. Always check that your guard bar has compatible mounting holes before ordering, as no adapters or clamps are included.

Uses and Placement

This protection block is intended for motorcycle guard bars, also known as engine bars or crash bars. It can be fitted to the lower or upper section of the bar depending on where you want additional contact protection. Its replaceable nature means that if it becomes worn or damaged, you can swap it for a new block rather than replacing the entire guard bar.

Event or Professional Use

Riders who take part in track days, off-road sessions, or training courses may find this block useful as a sacrificial bumper. In these environments, guard bars often come into contact with the ground during low-speed falls. A nylon block can take the initial scuff and be replaced afterwards. It is also suitable for riding schools or rental fleets where bikes are regularly used by different riders and bar protection is a practical concern. The block is not a substitute for a full crash protector but adds a layer of contact protection.

Everyday Home Use

For everyday road riders, the block offers peace of mind when parking or manoeuvring in tight spaces. A slow tip-over in a driveway or car park can scuff a guard bar, and this block provides a contact point that can absorb that damage. It is equally useful for riders who regularly park on uneven ground or use a side stand on soft surfaces. The block is small enough not to interfere with normal riding position and can be fitted without special tools beyond the supplied hex wrench.

Benefits and Buying Value

The main value of this product lies in its replaceable nature and the inclusion of stainless steel mounting hardware. Rather than accepting permanent scuffs on your guard bars, you can fit a low-cost nylon block that takes the wear. The simple design and included fixings make it a practical purchase for riders who maintain their own bikes.

Reuse and Low Maintenance

Because the block is a separate component, it can be removed and replaced when it becomes worn. There is no need to repaint or repair the guard bar itself if the block has absorbed the contact. Maintenance is minimal: check the fasteners periodically and re-tighten if vibration loosens them. The nylon material does not require lubrication or special care. If the block becomes deeply scored, replacing it restores the protective contact point.

Why Choose This Product

This protection block is a straightforward solution for riders who want a replaceable bumper on their engine bars. It comes with the screws, locknuts, and hex wrench needed for installation, so you can fit it as soon as it arrives. The choice of black, red, or blue allows a degree of colour coordination. It is not a universal fit for every bar, so checking your bar's mounting points and diameter is important. For compatible bars, it offers a simple way to add a nylon contact surface that can be renewed.
