2019年6月16日 · Revolutionary double-tube Twinwall design makes fatigue failure virtually impossible. The top-tier complete auto-clutch package from Rekluse. I had a 1995 as well, and while the motor was great, I thought they went backwards in the 1993 - 1995 era on ergonomics.

Overall, though, the 1992 Yamaha WR250’s good points far outnumber its faults. The WR is well finished, its engine starts easily, its seat is firm and shaped nicely, its suspension is...

2011年12月19日 · I just bought a 1992 yz 250. my first 2 stroke in 10 or 12 years. I cant wait to ride this bike.

2008年5月7日 · I picked up a 2 hour '92 YZ250 and used it for two years. The '92 was MXA's 250 of the year and overall a really stable bike. Much like the modern bikes, the best mod I made was to set the suspension up correctly.

That makes it the longest-running production dirt bike in the world–maybe even the longest running motorcycle model of any kind outside of Milwaukee and Russia. Perhaps more than anything, the YZ250 is known for the legendary riders who used it to win.

2008年4月1日 · Its a great bike even now. Its power is surprisingly strong compared to my 02 YZ250. A tad slower with a narrower powerband. I actually prefer the 92 at times if the track …

Yamaha YZ250: manuals, parts, microfiches.

With the constantly maturing 2-stroke single-cylinder engine and semi-double cradle frame as the basic components, it adopted a specially designed intake/exhaust system, a front fork with large-diameter tubes, a large-capacity radiator and more. Donny Schmit rode this machine to win the 250cc World Championship title.
