Alpina STS-2 Tubeless Supermoto Racer Kit

Alpina wheels are tubeless spoked wheels that truly set the bar in quality, performance, and craftsmanship. Hand-built in Italy, they are equally ready to be used on the race track, in the streets, and at custom shows alike.

• STS-2 Double Seal Technology:  Forged rims include two O-rings on each nipple, seal against precision-drilled holes in the rim profile to ensure a stable seal and a safer tubeless system.
• Forged Rims - WLT (WeldLess Technology): Forging the rims does not require any roll-forming or welding, so there are no weak points and the rim is much more uniform in strength.
• Less Maintenance: Easy balancing and less required maintenance thanks to forged rims combined with STS-2 Tubeless System.
• Innovative design: A rim without dimples for an incomparable aesthetical result and a clean design.
• Alpina Color Combos: Explore new color options from Alpina with their "RIDE" and "B-COLOR" combinations.

  * Moto-Master & Beringer Rotor Sizes
  If you select a 16" or 16.5" front rim size, the smaller 300mm rotors are used because they allow for much easier removal of the caliper. Otherwise, the 17" front rim size is paired with a 320mm rotor to allow proper spoke clearance for the back of the caliper.

Moto-Master Sprocket:

• Choose Size: 45-53 tooth count.

Rotor & Sprocket Hardware:

• Burnt titanium saves you nearly half the weight of standard steel hardware, and it adds a touch of color with its rainbow coloring from the burning affect.
