YFM400F Big Bear
Yamaha’s middleweight semi-automatic is a tough-as-nails workplace classic with the proven combination of 386cc air-/oil-cooled engine mated to a 5-speed, constant mesh transmission, with reverse.

Patented On-Command push-button switching provides fingertip access to either light steering 2wd or full traction 4wd – and should the going get really sticky… use the Diff Lock!

Factor in the superb trail holding of IRS (independent rear suspension), ventilated disc front and sealed wet brake rear stoppers, as well as full protective Grizzly bodywork and you’ve got one thing.

A rugged workday legend with the performance to match the reputation.

Big Bear’s plush, comfortable Independent Rear Suspension provides control and comfort, while a fully sealed oil bath rear wet brake allows long-lasting, outstanding stopping power even in the worst conditions.

For riders who crave ultimate control, a rugged 5-speed gearbox features a semi-automatic action and ultra-low ‘stump-pulling’ first gear. Naturally, there’s a reverse gear, so you can back out of what you get yourself into
