2010年8月17日 · anyone have a list of major changes from the 90's on up? I've been looking at some late 90's YZ250's, and I'm not sure if there's bad/good years, or what years share frames and engines for sparts swapping

The Yamaha YZ125 is a motocross racing motorcycle with a two-stroke 124.9 cc (7.62 cu in) displacement single-cylinder engine made by Yamaha since 1974. It is available to the public. For the first two years it was made with dual rear shocks, then changing to a monoshock. [3]

2010年1月22日 · Go buy a 110 width tire of your choice and run it, and then for you next tire, get the Sedona MX907HP in the 100/90-19 size. The Sedona tire is probably my favorite when using a 19" rear wheel.

While the majority of builds/project bikes go for broke (sometimes literally) in their quest to have the the most exotic unobtanium, it's nice to see a retro build stick to a stock look.

I found a 90' yz125 that im pretty interested in buying. The motor has supposedly been gone through and is mechanically sound. It has new tires and all it needs is the side number plates.

The Yamaha YZ125 two-stroke might be the number one motocross bike in the world. Actual production numbers are hard to estimate, but the YZ125 and 250 have had the longest production runs of any dedicated dirt bikes, starting in 1974 and continuing to this day.
