According to Japanese media reports, Yamaha plans to expand its recently launched model Tricity line of three-wheeled vehicles. Tricity will be equipped with dual head light size, the characteristic time for the family as a T-Max . While Tricity comes with a 125cc engine, a new frame is supposed to put the engines from 250cc to 500cc, possibly with a larger diameter cylinder than it is now at the T-Max. It is possible that the novelty will be presented this fall at Europe's largest EICMA Motorcycle Show in Milan, Italy, which will be held in November. How much will the T-Max on three wheels, and whether or not it will be another T-Max or have a new model, it's unclear.
