Langens New Lightspeed Turbo with Carbon Fibre Body, Curvy Frame

Langen LS12 Lightspeed Turbo, which Langen Motorcycles has been teasing and developing as an ultra-exclusive, high-performance machine.

Here’s a breakdown of the expected key elements.

• Name: The motorcycle is part of the Lightspeed model line, with the turbocharged version being the LS12 Lightspeed Turbo (or sometimes just LS12 Turbo).¹ The standard version is the LS12 Lightspeed.
• Curvy Frame: The bike utilizes a bespoke tubular steel trellis frame (sometimes described as a space frame), which, combined with the design of the carbon fiber bodywork and the visible rear twin-shock suspension, gives it a distinct, elegant, and curvy/flowing aesthetic compared to many modern superbikes.² It’s often described as having a retro-muscle cruiser style.
• Twin Motor: This refers to the V-Twin engine.³
  • Standard Lightspeed: Uses a naturally aspirated 200cc+ V-Twin (sourced from Buell/Rotax) that produces about 185 hp.⁴
  • Lightspeed Turbo Tease: The turbo variant is built around the same 1,190cc V-Twin engine, but with a turbocharger added to produce a staggering output of up to 200+ hp in “full power” mode (with a 220 hp “road mode”).⁵

🏍️ The Teasing Goal:

The LS12 Lightspeed Turbo is essentially an ultra-exclusive, turbocharged evolution of their already impressive LS12 Lightspeed muscle cruiser/roadster, featuring:

• Power-to-Weight: An absolutely astonishing ratio, expected to be one of the highest in the world due to the massive power from the V-Twin Turbo and the bike’s lightweight construction (carbon fiber bodywork, forged aluminum wheels).⁶
• Technology: Custom ECU and a ride-by-wire system engineered to carefully manage the powerful turbo boost and minimize lag.⁷
• Limited Production: Like their previous model, the “Two Stroke,” the Lightspeed and its Turbo variant will be built in extremely limited numbers.

The carbon fiber bodywork is a critical element of the Langen Lightspeed’s design and performance strategy.

It’s not just a styling choice; it’s fundamental to achieving the extraordinary power-to-weight ratio that makes the Lightspeed and its Turbo variant so extreme.

🖤 Carbon Fiber on the Langen Lightspeed

The carbon fiber is used extensively on the bike’s visible components to keep the weight incredibly low while maintaining the sculpted, elegant aesthetic you mentioned.

• Weight Reduction: The strategic use of carbon fiber is one of the main factors that helps the standard Lightspeed achieve a dry weight of just 185 kg (408 lbs). This gives it a spectacular 1:1 power-to-weight ratio of 1 horsepower per kilogram (1,000 hp per tonne). The Lightspeed Turbo aims to keep a similarly low weight, making its 200+ hp output truly ferocious.
• Body Components: Nearly all of the visible body panels, including the:
  • Curvy Fuel Tank
  • Headlight Cowl
  • Front Fender
  • Tail Unit/Seat Unit
  • Radiator Shrouds
  • …are constructed from lightweight carbon fiber.
• Aesthetics: The carbon fiber is often left partially or fully exposed, contrasting beautifully with the visible tubular steel space frame and the CNC-machined aluminum “jewelry” (like the yokes, swingarm, and wheels), giving the bike a high-end, bespoke, and modern-classic race machine look.

In short, the carbon fiber is an essential component that allows the bike’s 200+cc V-Twin engine, especially in its 200+ hp Lightspeed Turbo form, to challenge for the title of the “world’s fastest production motorcycle.”
