Langen Two Stroke V-Twin


This street-legal two-stroke sportbike is the creation of Christofer Ratcliffe, from Langen Motorcycles, based in Wigan, UK.

Christofer said: “The company has been founded with the aim of producing motorcycles with a simplicity and purity of days gone by, like the Ton-Up Boys and their café racers, yet pushing the limits of modern technology. My dream has always been to create a small piece of British motorcycling history. To be able to launch this special motorcycle under a completely new brand really is a dream come true. The aim is to continue to push boundaries and create more interesting bikes, which we hope will really please people.”

The Langen Two Stroke is powered by a 249cc, 90º V-twin engine and advanced fuel-and-oil injected unit developed by Vins Motors in Italy producing 75hp at 11700rpm and 45Nm at 11700rpm. 

EFI, computer-controlled oil injection, electronically manipulated exhaust valves, and carbon fiber reeds work together to keep the power up while controlling emissions to achieve street legality.

A tubular aluminium ‘space’ frame and swingarm that is ultra-lightweigh are handmade from large-diameter aluminum tubing. To connect the pieces together, the connection points are either machined or bonded.

Front Suspension is 43mm Öhlins ‘Right way up’ forks with compression, rebound damping and spring pre load adjustment.  Rear suspension consists of dual shock bespoke Ktech Piggyback Razors, compression and rebound damping, spring preload and length adjustment.

Braking power consists of twin 300mm Brembo discs (265mm rear) which are clamped by HEL radial billet callipers on the front and back.

Carbon fibre tank and bodywork are hand-laid in Wigan and given a 24ct Gold Leaf detail finish, this sets the parts off beautifully, especially with the bespoke billet aluminium components.

The carbon fiber used for the bodywork and fuel tank is hand made. The claimed dry weight is only 114 kg /251 lbs.

Each Langen Two Stroke is a custom motorcycle, as they are built-to-order.  Each machine is individually numbered, with the initial build limited to 100 units.
