2016年7月7日 · I personally loved mine. Other than regular maintenance it was very reliable. My dad was very meticulous about air filter cleaning, regular piston & ring changes, oil changes, etc. We never even had a problem with the wheels. We raced my 1984 YZ125 for two full seasons with nothing more than regular spoke tightening.

2012年3月7日 · The wrench report mods did very little, we had Pro-Circuit do a full head/cylinder mod along with a new pipe and boyesen reeds for a customers 1985 YZ125 = it was still slower than the stock 1984/85 KX125's we also sold. Yes the 1983 cyl is a must have for performance.

2009年12月23日 · I currently own both a 1982 and 1983 YZ125. The 1982 is a great bike. I've raced it a handful of times in past couple years. Motor is very competitive. Setup your suspension and you'll love it. The heavy front end feeling of the radiator goes away quickly once you start riding it hard. I picked up my 1983 a year ago and have one race on it.

2018年2月20日 · The '83 YZ125 was my favorite bike back in the day. I had YZ125s from 1980-1983, went to CR125 in 1984 which was a mistake, but the YZ125 in '84 was bad too... Should've kept the '83 YZ125 for 1984...

2013年11月1日 · I also owned quite a few YZ125's from back in the era. The 83 K was my favorite bike of all time. In fact, i am rebuilding one now as a Ron Lechien tribute bike.

2011年10月20日 · My neighbor got his new 1985 YZ125 same time as I had the new 1985 RM125..I rode his and knew why both of our bikes where "left-over" at the dealers and discounted late into spring of 1985...CR125s did almost everything great,,the KX was the motor of the 125 class. I ate enough roost to never forget.

2022年2月19日 · Does anyone have any suggestions,on how to compress this enough to get the clip off.I’d buy a tool,if it helps/works..also..I want to install the cartridges from a set of 88 forks..I saw a feed once,a guy did it,but said the bottom of the tubes would need machined a little..Anyone have any insigh

2013年4月11日 · Hello All, I've finished my motor build YZ125 1979 Race Build and the bike has a boatload of top end, but is still lacking in mid range. YZ125 ignition mapping? - Old School Moto - Motocross Forums / Message Boards - Vital MX

2011年1月19日 · Aluminum swingarm and shock from a 1982/83 Yamaha IT175 is a easy conversion. For some reason the IT175 rear axles are hard to find, you can also use a rear axle from a 1980 YZ125. You can use the YZ100 linkage or the IT175 same same. Use a chain rub block from a 1984 IT200 it is a one piece and bolts on to the IT175 swingarm.

2014年9月5日 · Chassis / suspension wise, the 83-84 was an improvement over the 82. Unfortunately, the engine package for the 83-85 YZ125 was sad. Yamaha small bores always made their power high in the rev range. The 82 had a very fast engine, I'd say the fastest stock 125 of '82. The 83-85 lost the great top end scream of earlier YZ125's.
