    The 2021 Yamaha YZ250: MotoCross Competition With A Big Engine!​


    The 2021 YZ250 is Yamaha’s entry into professional national motocross. Powered by a 250cc 2-stroke, liquid-cooled, crankcase reed-valve single cylinder, the bike is designed to take a complete thrashing and still win every heat.

    The no-compromises mentality of the YZ205 shows through with a full suite of competition parts already fitted from Yamaha’s factory. KYB fully adjustable front and rear shocks, with 48mm inverted forks up front travelling 11.8 inches and the adjustable link monocross at the rear giving 12.4 inches of travel.

    Braking is through a 270mm floating disc up front, clamped by a 2-piston competition caliper, and a 245mm disc out back with a single-piston competition caliper, all to say that it is premium Japanese engineering in one package. The front wheel is 21 inches in diameter, with the rear at 19 inches. Ground clearance is at 14.2 inches (360 mm).

    A cross-country competition variant exists in the YZ250X, which is listed for Canada and Europe. Much like the YZ125X, the major difference is different gearing, valves, and a more mid-range torque for scrambles and hill-climbs.

    The 2021 Yamaha YZ250 starts at $7,499 USD / $8,299 CAD, with the YZ250X at $8,499 CAD.
