    1. Anodization or powder coating

    Most rear top racks on the market are powder coated or anodized.

    The top plates of all our top luggage racks are powder coated.

    The reason is simple. Although all edges on our top plates are chamfered by CNC mill, additional rounding of the edges that powder coating provides is a great benefit. Also, powder coating provides smooth and slick surface. This is very important as it greatly increases the life of straps used to secure soft luggage.

    2. Durability of powder coating

    We use only high quality IGP Duraface powders, and we strictly stick to the procedures set by the powder manufacturer. These powders are very durable, weather resistant and have very good surface hardness.

    However, when the soft luggage is strapped to the rear top rack, dirt and fine dust will enter between the rack and the bottom of the bag. While riding, the bike will vibrate, and this dirt will act as sandpaper. So, some blemishes on the top surface of the rack will appear. On some parts, where the bag is pushing hard on the rack, even “hot spots” may appear, where the powder coating will be completely removed. All this is perfectly normal and can’t be avoided if the bike is used in off-road conditions. Just like the engine case will have visible blemishes caused by the moto boots. Just like the rack-less luggage will leave the marks on the side plastics. It is part of the normal and expected wear.

    Mind that all materials we use for our racks are non-corrosive - aluminum and stainless steel. So if some hot spot appear, they won't rust and won't cause any functional issues. 

    3. Weight limit for rear top racks

    We don’t provide strictly determined max load limits for any of our top luggage racks.

    When we design our racks, we do many CAD simulations to determine what material we should use, where the carriers or racks should be stronger and where we can remove some material to save the weight. It is an integral part of the design process. Also, we test our racks rigorously. And very important, we have extensive experience as we design and sell racks and gather customer feedback since 2015.

    So, why can’t we give precise max load limits? We design racks for adventure bikes and adventure bikes are used under various circumstances. On the road, off the road, on smooth gravel roads or on high-speed rocky tracks. Also, suspension on these bikes varies a lot and it affects the forces acting on the luggage racks (and on the frame of the bike). Rider styles also vary a lot, some of use ride cautiously, others trash the bikes. And it is all OK and to be expected. 

    Static load is one thing and it is easy to determine it. But dynamic loads, real-life loads and forces, cycles, oscillations etc. are so diverse that we just can’t give a solid and precise answer, without being too conservative.

    But fear not – just use common sense and you will be fine.

    Generally, info below applies to all our racks. Some of them are stronger, due to the construction of the bike (large billet rack for 790/890 Adventure and 901 or top rack for 2021+ 1290 Adventure) but none is weaker.

    If you use the bike only on the road, where won’t be any harsh hits, you can safely carry 10-15 kg on the rear rack.

    If you ride off-road, this comes down to 5-10 kg (this load refers to the load on the top plate of the rear rack, not the entire load of the rack-less system). Try to place the luggage as close to the front of the rack (towards the rider) as possible and avoid strapping heavy objects (like full tool roll or fuel canister) on the rearmost part of the rack. Heavy bags towards the front, light bags on the rear of the top rack. Secure the luggage nicely, so it doesn’t bounce on the rack. Try to spread the load – instead of mounting one bag on the rack and the other bag on that bag, try placing both bags on the rack (if possible). This will prevent or minimize oscillations of the rack (up-down movements) and these movements lead to material fatigue. Remember, these oscillations are the problem, not the weight per-se. This is the reason why rack-less luggage is so popular and why it is a very good choice – rack-less luggage will spread the weight over rear part of the seat, sides of the bike and rear top rack. This will fix the rear top rack and it will minimize the oscillations.

    Also, occasionally check the bolts for tightness. And don’t overtighten the bolts, this can weaken them!
