Z spokes, what a "great" idea

I love those articles. Thanks for the link.
Not Yamahas finest moment by all reports!

at least the mags told it how they saw it.

were they really that bad ?

My understanding is that the 84/85 were slugs for the same basic reasons as the 90~93 models were: all of the power producing parts were designed to work at different points of the rev range. Not that the fundamentals were wrong, or that any single part is "wrong", just that the parts didn't work together.

I've had a couple of YZ125Ls. I didn't think they were that bad, but nor were they bikes that I found easy to love.

Engine should make really good power, I would look at the PV opening/pipe /ignition mainly the pipe

They claim in the article it was extremely difficult to get good power back in the day, no matter what was done, including fitting older model barrels.

I had an 83 125 for my son - one of the most impressive bikes I have ridden.

Well I am very skeptical about analysis from US mx magazines, a similar Yamaha cylinder has no trouble pushing 30hp out even with relatively small 30mm carbies.

Only one way to settle this then Lozza. We need to find you a YZ125L, to carry out some scientific experiments on.

yet the it "L" models were good??

Shit yeah , if all the cycle parts break after the first meeting I'll count that as a win

Same here,I had one for years and still believe its the fastest 125 I have ever riden.

Story claims the '83 was faster than the '84 by a wide margin.
Goes on to say some resorted to fitting '83 cylinders.

It was two steps forward, one back during the steep learning curve of Japanese MX bikes in the crazy rate of development from '73 - '88.

Some would say the '82 RM125 was slower than the "Case Reed" '81. At least it was universally praised as easier to ride. I believe they went back to the Case Reed after two years.

These days it's bold new graphics one year, "revised suspension" settings the next.... Even "total redesigns" are fairly "incremental".
