The Alpina STS2 system is an evolution of the STS1 system. It's an all brand new generation of tubless spoked wheel, realized with innovative forged rims and the new STS2 system: a surface without dimples and welds, increased thickness and improved resistance.

Motorcycles wheels have always been conceived as mere mechanical parts, “functional tools” with the only task of transmitting power generated by an engine. A secondary part in the economy of the motorcycle, often overshadowed by more “noble” components.

Alpina strives to give spoked wheels a soul, a strong character and identity, and make it an essential part in motorcycles’ performances and design.

Alpina's strength is a century of experience in the production of spokes and nipples, side by side with the world’s greatest manufacturers of bicycles and motorcycles.

Two souls live within the same company: an industrial division – specialized in mass production of high-quality spokes and nipples – and the tubeless wheels division, an atelier where our craftsmen create exclusive wheels, tailored on our customers needs.


  • Safety. Tubeless wheels prevent tyres from deflating immediately after punctures and are easier to be repaired.
  • Weight. Save from 800g to 2kg with the removal of inner tubes.
  • Hump. Our rims are provided with a security hump that prevents the tyre to come out from its position in case of puncture.
  • Tyre consumption. Tubeless wheels ensure an increased durability of tyres.
  • Plug & Play. Each wheel model is suitable with its corresponding motorcycle models, without further adaptations.


STS2 Functioning:

Alpina's STS2 nipples have O-Rings that are positioned inside the profile of the rim. This rubber ring works as a permanent seal, with an extremely durable resistance to temperatures and atmospheric agents. A Safety Clip is added in order to prevent the nipple from being ejected out of the rim in case of spoke breakages or severe punctures.



The new generation of Alpina Tubeless wheels is equipped with forged rims instead of standard, extruded rims: produced starting from one, single piece of aluminum, without weldings and dimples (Weldless Technology), these products represent the best available technology in aluminum rim manufacturing.

Top performances.

Increased thickness in the center of the rim (up to 12mm) and perfect roundness. Incredible resistance even during the most extreme off-road activities, better handling and riding precision.

STS 2 Technology.

Double seal. STS 2 Nipples are an evolution of our standard tubeless system, equipped with a single O- Ring. The increased rim thickness of 12mm allows the use of a double O-Ring for a durable seal and a safer tubeless system.

Innovative design.

A rim without dimples and weldings, for an uncomparable aesthetical result and a clean, modern design.
