Yamaha TDM 900
The Yamaha TDM 900 first appeared in 2002 and replaced the Yamaha TDM 850. Very often TDM900 is considered as the next generation of TDM850, however, despite the general concept and similar appearance, they are radically different from each other.
The main differences between Yamaha TDM900 and Yamaha TDM850:
- Deltabox aluminum frame instead of steel - 29% lighter;
- New modified and lightweight engine with increased volume;
- Injection power system instead of carburetors;
- 6-speed gearbox instead of 5-speed;
- New 4-piston front brakes from the sporty Yamaha R1;
- New 1-piston rear caliper (instead of 2-piston);
- The appearance of modifications with ABS (differs by a black frame and the name - Yamaha TDM900A);
- New lightweight 3-spoke wheels, increased wheel width (120 and 160 mm, respectively);
- Reduced curb weight (from 232 kg to 221 kg).
However, the main advantage of the Yamaha TDM 900 is the absence of the "sores" of the previous TDM850 - all the problems of the older versions of the motorcycle have been eliminated. This effect was achieved both by using more advanced mechanisms (the problematic rear caliper was replaced with a new, more advanced one) and modern solutions (the problem with carburetors was solved by the introduction of an injector), as well as by the refinement of existing units (engine lightening, the use of other materials and elements).
The main modifications of the Yamaha TDM 900:
- Yamaha TDM900 is the standard version of the motorcycle.
- Yamaha TDM900A - version with ABS. It has been available on the market since 2004. Visually distinguished by a black frame. In a number of European countries, only these versions were present (due to legislation obliging all new motorcycles to be equipped with an ABS system).
The Yamaha TDM900 was based on an in-line 2-cylinder liquid-cooled engine with a volume of about 900 cc and 86 hp. power and almost 89 Nm of torque. The engine is medium-speed, with maximum performance at 6000-7500 rpm. Like previous TDM850 modifications, the new TDM900 engine was also equipped with a 270 ° crankshaft, due to which the ignition of the mixture occurred asymmetrically (with a delay of half a stroke), which made the engine work similar to a V-shaped arrangement of cylinders.
Also among the features of the Yamaha TDM900 should be distinguished an aluminum frame, adjustable suspensions, powerful brakes (taken from the sports Yamaha R1), a 20 liter fuel tank and 221 kg of curb weight (224 kg - for the version with ABS).
2010 was the last year of production of the Yamaha TDM900, but official sales were up to and including 2012. Unfortunately, the model series did not receive a direct continuation. Only in 2015, a modification of the MT-09 model appeared - Yamaha MT-09 Tracer, which can be considered as a kind of continuation of the TDM900, although these are completely different motorcycles.
