2015 Yamaha YZ250

Posted on by  

Weighting only 227 lb. (wet) and propelled by a 250 cc, 2 stroke engine, the 2015 Yamaha YZ250 offers an incredible power to weight ratio which helps it deliver first class performances even on the toughest terrains.

The motorcycle’s engine is fueled by a 2.1 gallons fuel tank and its power is transferred to the ground by means of a constant mesh five speed transmission with multiplate wet clutch.

Among the improvements made for the 2015 model year you’ll find a new style, the latest generation KYB Speed Sensitive fork, a clutch lever position adjuster and new Dunlop MX52 tires.

The Yamaha YZ250 is also fitted with lightweight 21 inch front and 19 inch rear Excel rims which help reduce unsprung weight.

The Yamaha YZ250 is offered with a starting price of $7,290.
