Yamaha sports snowmobiles in 2011 were represented by only three models: FX Nytro R-TX, FX Nytro X-TX and APEX X-TX. All these models are suitable for fast driving along natural
trails and are of the rough trail type. It is important to recall that all of these models are 4-stroke. This is the general policy of Yamaha on environmentally friendly technology. Let us focus
on the new product of 2011 for the Russian market — the Yamaha APEX X-TX model. This is the first snowmobile to feature an EPS electric power steering system that sets new standards for handling
and stability. This model is equipped with a modified four-cylinder engine with an EXUP exhaust system and a fuel injection system. These improvements were made in order to significantly increase
peak power and torque at low and medium ranges of engine speed. A long 144 ”/ 3658mm track, new front suspension geometry, Dual Shock® suspensions and wide skis make it easy to cross any trails.
