DERBI / GILERA / APRILIA SX 50cc EVO BLACK - SEAT COVER

Founded in 2018 by Mickael Galaup, Bikesellier (BKS) was born from a deep passion for motorcycles and 100% handmade craftsmanship. Each cover is designed, crafted, and carefully finalized in our workshops in France, to give your machine a unique identity (50cc, Supermoto, Electric Motorcycle).

Unlike factories or import sites, we do not have a finished product warehouse. When you validate your 3D configuration, our team cuts out the specific pattern for your saddle, embroiders your customisation, and then proceeds with a hand-stitched assembly. This high-end French craftsmanship requires patience, for a result that cannot be found elsewhere.

We do not use basic materials. Bike Sellier uses a professional anti-slip grip essential for Supermoto/MX braking, genuine Alcantara, high-resistance textured synthetic leather, and assembles it all with unbreakable and waterproof marine-grade sewing thread.

Yes, absolutely! More than 95% of our young riders install their seat covers themselves.
Our patterns are precisely calculated. Remove your old staples (with a flat-head screwdriver), position the cover, pull to smooth out wrinkles (our elastic material does the rest), and secure it with a simple stapler (6mm staples).

If your foam is severely damaged (missing pieces due to a fall), stretching a new cover over it will create an unsightly bump. We strongly recommend injecting polyurethane foam into the cavity, sanding it with sandpaper once dry to restore the original shape, before stapling your new BKS cover over it.

We provide a picture tutorial with all the tips (using a hairdryer to soften the fabric) on our BKS Seat Cover Installation page.

No. In accordance with intellectual property laws, reproducing registered logos for commercial purposes is totally illegal (counterfeiting). As an official French craftsman, Bike Sellier strictly prohibits such practices, unlike black markets and distant import sources. However, you are completely free to customize the typography, your first name, or your personal team logo!

The Grip (the rough material on the seat) is crucial in Enduro, Motocross, and Supermoto. It allows you to stay anchored to the bike during heavy braking without sliding onto the tank, preventing fatigue and improving your riding performance. On the open road, it is also a huge safety asset.

Whatever you do, don't use a high-pressure cleaner (Karcher) 5cm from the grip, as this will fray the technical weave or ruin the Alcantara!
Apply soap or our special BKS cleaning kit, use an extremely soft-bristled brush, rubbing gently, then rinse from a metre away with low pressure. Always allow to air dry or use a microfibre cloth.

Yes, we have a huge rider base in French-speaking Europe. Bike Sellier exports daily to Switzerland, Belgium and throughout the rest of Europe, allowing our cross-border enthusiasts to access French craftsmanship without paying the exorbitant prices of small local saddlers.

In accordance with legal directives related to Craftsmanship, any custom-configured item (3D Cover, embroideries) is manufactured specifically to your image and therefore cannot be returned or canceled once production has begun.
Returns are only possible on non-personalized products (maintenance kits, etc).
