It’s summer, and that means it’s time we start seeing next season’s offroad bikes debut. Right on schedule, Yamaha has introduced its 2021 motocross series, including a much-updated YZ250F.

Yamaha’s four-stroke quarter-liter MXer gets a new head, with updated camshaft and the intake system re-design. The clutch, transmission, shift cam, water pump impeller and ECU are all updated for 2021, too. The result? Yamaha says the engine makes more peak horsepower, with gains in the mid-range and top-end, retaining its low-end grunt.

Yamaha also re-worked much of the rest of the bike, re-tuning the suspension and also re-working the frame and other chassis bits (new handlebar clamps and updated triple tree). The brakes are beefier, too. The YZ250F should be in Yamaha’s North American dealerships by fall, with an $8,299 MSRP in the US and $9,699 in Canada.

You’ll pay more if you want the Monster Energy Yamaha Racing Edition graphics. These bikes have the same mechanics, but with a race-inspired sticker kit. So far, we’ve only seen Monster Energy versions of the 250 and the YZ450F (unchanged for 2021).

While the YZ450F hasn’t been updated for next season, Yamaha is changing up the YZ450FX cross-country machine for 2021, at least in some markets. This machine gets roughly the same make-over as the 250 MX bike: top end changes (new cylinder head, high-compression piston), a slick-shifting gearbox, a revised frame, new brakes and changes to the suspension’s compression and rebound settings.  The GNCC-friendly machine will cost $9,699 in the US, $10,899 in Canada.

As for the rest of the lineup, Yamaha has not made any major changes—the bikes look different for 2021, with new paint, but  that’s it. Visit Yamaha’s US site or Canadian site for full specs and pricing.
