According to the blurb from brand Y: Many believe that the TDM900 is Yamaha's best kept secret, but its popularity in Europe points to something more than cult status. Product planner Hennes Fischer remembers:
"It all started in the beginning of the nineties, when we wanted to create a bike that would be fun on bumpy, minor roads. Most team members preferred touring trips using tiny alpine pass roads. But bikes at that time either needed full concentration on these small roads or simply could not cope with the constantly changing surface properly. Something in between a big enduro and a streetbike seemed ideal for this purpose. The answer was TDM850 launched in 1992. The bike instantly connected with French bikers, who were already customising their enduros with street tyres and upgraded brakes. In the years to come TDM convinced motorcyclists all over Europe of its many benefits. Yamaha product planners are often told that the TDM is many bikes in one: a sportsbike on small roads, a tourer on longer trips and a powerful commuter in city traffic."
