Triumph build supercharged T120s for Glemseck 101

Published: 02 September 2016

Triumph Motorcycles have entered two stonking supercharged Thruxton R bikes in the ‘Essenza – The Essence of Motorcycles’ challenge races that take place tomorrow, September 3 at the Glemseck 101.

The first is a sleek marriage of modern racing lines with a classic T120 parallel-twin heart, the second a dark brooding retro street fighter.

'The White Bike' which will be ridden by Triumph Global Ambassador, Carl Fogarty, while the 'The Bulldog' will be ridden by Christophe Lentsch from 1000ps.

‘The White Bike’ gets some aerodynamic efficiency from its Daytona 675R fairing and seat, while it also gets a braced, MotoGP-inspired swingarm has been hand-crafted in the factory and revised gearing helps to feed the power to the tarmac.


‘The Bulldog’ is more brutal. It also gets a deep-braced swingarm, with the front dominated by a custom Speed Triple R intake fairing, repurposed to house the LED front lights. Final detail touches include the factory-accessory seat and matching factory-accessory black wheels.
