- Vespa GTS Rims for Royal Alloy—the adapter set makes it possible!
More choices, more personalization, and completely new styling options for your Royal Alloy!
Together with ScooterTec from Deggendorf, we’ve developed a rim adapter set that opens up the vast world of Vespa GTS rims for the Royal Alloy GP, TG, and JPS models with 300 to 350 ccm engines.
The idea for this was born at our Scooter Center Open Day in the spring of 2026. What began as a shared vision among scooter enthusiasts has now become a reality: With the new wheel hub set, 12- and 13-inch Vespa GTS rims can be mounted on the corresponding Royal Alloy models.
A whole new world of custom wheel styling
Whether classic multi-spoke rims, sporty racing designs, or eye-catching color combinations—the selection of Vespa GTS rims is vast. Now you can take advantage of this variety for your Royal Alloy, too.
From elegant and classic to sporty and extravagant, the possibilities are endless. The black powder-coated rear hub, in particular, offers a great foundation for custom combinations. Black, silver, gold, or bronze rims—there are virtually no limits to your creativity.
High-Quality Materials and Sophisticated Technology
To turn your idea into a functional conversion, ScooterTec and Scooter Center have developed a specially tailored wheel hub set.
The rear wheel hub is made of high-strength 42CrMo4 tempered steel and features a black powder coat finish. The front wheel hub is made of 6083 aluminum and features a silver powder coat finish. Both components are manufactured in Germany.
Every detail has been considered for the brake components as well: The rear wheel hub comes pre-assembled with a Braking brake rotor and a modified ABS sensor wheel. The front wheel hub is equipped with wheel bearings.
The set also includes a ByBre brake caliper from Brembo, complete with brake pads. A customized ABS sensor mount, spacers, a special hollow screw with new sealing rings, and other small mounting parts round out the package.
12 or 13 inches—the choice is yours
The adapter set allows for the installation of Vespa GTS rims in two sizes:
The maximum tire width on the front wheel is particularly important. Due to space constraints in the area of the anti-dive suspension, tires that are too wide may come into contact with the anti-dive damper mounting. The actual clearance must therefore be checked for each wheel-tire combination.

Important Installation Notes
This kit affects safety-critical components of the suspension, braking system, and ABS system. Therefore, professional installation in accordance with the enclosed installation instructions is absolutely essential.
Only M8 × 35 mm bolts of strength class 10.9 may be used for rim mounting. The distance between the ABS sensor and the sensor wheel must be 0.5 to 1.5 mm. For the rear ByBre brake caliper, use only the supplied hollow screw with the new sealing rings.
After the conversion, the brake system, ABS system, bolted connections, and free movement must be carefully checked. We recommend that installation be performed by qualified professionals.
Important Information Regarding Registration
The rim adapter set is supplied without an ABE, TÜV certificate, or parts certificate. Questions regarding possible individual approval and registration should be clarified directly with ScooterTec Deggendorf and the responsible testing agency before the conversion.
A New Look for Your Royal Alloy
With the ScooterTec x Scooter Center rim adapter set, your Royal Alloy gains access to a whole new world of rim design. High-quality materials, German manufacturing, and carefully matched components combine with the virtually limitless design versatility of the Vespa GTS.
An idea that originated at our Open Day and now opens up entirely new possibilities for individualists.
