Yamaha Wr 250 F

When Yamaha dropped the first WR250F in 2001, it genuinely changed what serious enduro riders expected from a four-stroke — the DOHC motor pulled cleanly from about 4,000 rpm and kept clawing hard past 9,000, which felt almost obscene for a 250 single at the time. At 118 kg wet it was noticeably heavier than a KTM 250 EXC two-stroke, and you felt that mass grinding through tight technical singletrack on a hot afternoon. The close-ratio gearbox was a revelation though — you could pick exactly the right gear for every rocky climb and it stayed there, and those titanium valves meant the top end stayed in spec longer than any Japanese four-stroke had any right to. My biggest real-world gripe was the jetting: carb ran lean from the factory to pass emissions, and until you re-jetted it and pulled the throttle stop, you were riding maybe 80% of the bike.

The Gen 2 WR250F finally sorted the gritty, abrupt powerband of the early bikes — the revised head and updated carb jetting gave it a cleaner, more usable midrange that you could actually work with through tight single-track without constant clutch slipping. At 118 kg wet it feels lighter than the numbers suggest once you're moving, and the improved suspension linkage made the rear end far less prone to packing up on rocky descents. That said, the 985 mm seat height is genuinely brutal for anyone under six feet on technical terrain — you will dab and you will pay for it — and the stock Mikuni flatslide carb still needs a rejetting the moment you leave sea level. Maintenance intervals are aggressive for a DOHC motor; if you're not comfortable checking valve clearances every 25 hours, budget for shop time or this bike will punish your neglect quietly and expensively.

I put two seasons and roughly 4,000 km on a 2013 fuel-injected WR250F, and that bike genuinely changed how I think about enduro riding — the revised frame is noticeably stiffer in the front triangle without killing feel, and the KYB suspension swallows square-edged rocks better than anything else at this weight. The FI version cold-starts without fuss at 6 AM in the mountains, no choke dance, no flooded engine; it's a small thing until you've been stranded with a carbed bike in freezing air. High-rpm power is addictive but merciless — let the revs drop below 8,000 in tight switchbacks and it stumbles badly, demanding constant clutch work that'll gas your forearm on a long technical day. The 985mm seat height also genuinely limits who can ride this confidently; I'm 182cm and it suits me, but I've watched shorter riders fight it all day.
