Bumpers for Motorcycle Crash Bars Ø 25 mm | Tubular protection with rubber pads, 2 pieces

Measure the tube’s outside diameter with calipers, or wrap a measuring tape around the bar and divide the circumference by 3.14. On a 25 mm bar, the circumference is approximately 78.5 mm. If you don’t have the tools, the specification is almost always listed in the engine guard’s technical data sheet.

No. The clamp is shaped for a 25 mm tube: on a smaller diameter, it would be loose and rotate; on a larger one, it would not close. Do not use improvised shims to adapt it, because in the event of a fall, it is precisely the grip on the tube that does the work.

Only for tubes with a 25 mm outside diameter. This is the standard size for adventure crash bars, but it is not universal: no spacers or adapters are available for other diameters. If your bar is 22, 28, or 32 mm, this product is not suitable for you.

With a caliper, measuring the tube’s outside diameter is immediate. Without a caliper, wrap a tailor’s tape measure around the bar: a 25 mm diameter corresponds to a circumference of approximately 79 mm.

No, just an Allen key for the clamp’s four screws. Installation does not require removing the crash bar: the guard opens, is positioned at the chosen point, and closes around the tube.

At the bar’s most protruding point—the part that touches down first if the motorcycle falls—this is usually the vertical section at engine-block level. If you’re unsure, place the motorcycle on its side stand and see which area of the engine guard is most exposed.

The clamping is secured with four bolts, which distribute the grip better than two. As with any component bolted onto the motorcycle, you should still check the tightness again after the first few miles and then periodically.

Yes, at any time: loosen the four screws and reposition them. They do not drill into or modify the bar, so the adjustment is completely reversible.

Two, one per side, each with its own four-bolt clamp and self-locking nuts. There’s no need to buy additional hardware. LOBOO recommends installing a pair on each side for maximum coverage; in that case, two packages are required.

108 g each, so 216 g per pair. This weight does not affect the motorcycle’s handling, especially since the guards are positioned low and close to the longitudinal axis.

Yes. The mounting uses a clamp and does not depend on the bar brand: LOBOO states compatibility with most systems on the market, including GIVI, Touratech, and original BMW and KTM crash bars. The only requirement is a 25 mm tube.

No. The guard closes around the tube by tightening the upper and lower shells with four M4×20 screws: no drilling, no welding, no modifications. An Allen key is required, and LOBOO specifies a tightening torque of 5 N·m, warning not to overtighten to avoid damaging the screw head.

The clamp uses locknuts, and the rubber surface in contact with the tube is textured, so it grips instead of slipping. As with any bolted accessory, it’s worth checking the tightness again after the first few miles.

Each protector consists of three pieces: an upper and lower shell made of technical plastic, which resist abrasion against asphalt, and an intermediate rubber element that absorbs impact energy. The three pieces are separable, so if damage occurs, only the worn part can be replaced instead of the entire bumper.

It depends on how much they have been used. They are sacrificial components: after a tip-over or scrape, they should be inspected, and if the shell is deformed or deeply abraded, it is best to replace them. That is precisely the purpose of the product: this wears out instead of the bar.
