Was just reading this article on KHI's site and couldn't find any photos of the works bikes used in the All Japan event they mention. https://www.kawasaki-cp.khi.co.jp/msinfo/press/kdc/vol04_e.html
Anyone happen to have pics of either the 1980 KX125SR or KX250SR used in that race? It had Uni-trac, water cooling and a front disc, two years before the first production KX came with front disc.

This was Jeff Ward's 1980 SR125. I don't ever remember it having a disc brake though. Sounds like they only used them in Japan at the time, and may have been late in the year. The beginning of the 1981 season is when all of the American factory riders had front disc's on the SR's. 1982 they were in production. Honda didn't put a front disc on until 1984, and it took Yamaha and Suzuki until 1985 to figure out that front discs were the way to go. Kawasaki was also the first manufacturer to put a REAR disc on a dirtbike in 1986. Most riders of the time didn't like the rear disc because it didn't have a floating rear brake arm and it was touchy. Motocross bikes were changing by leaps and bounds during this era. You really were at somewhat of a disadvantage if you owned a year old bike, or one that didn't have the latest technology.
*edit I just found a pic of Goat Brekers SR in 1980 from Matthes' site. Notice the caliper in front of the fork leg - in 1981 they moved it to the rear of the fork leg:
When did Suzuki first race with the full floater prototype?
*Cool side note, while looking for 1980/81 Mark Barnett bike pictures I can across this. 1983 RH250 that carried the fuel in a alloy tank where the air box would go and the air box is housed in the fuel tank.. pretty cutting edge for the time.
The Full Floater was on Suzuki works bikes through most of the 1980 season. Kent Howerton, who won the 250 National championship that year, started out on a dual shock bike, while his teammates started on the Full Floater. By mid-season, he had switched to the full floater also. That was a stolen design btw. Suzuki had a lawsuit against them for it and was forced to pay the inventor. Probably one of the reasons that it was abandoned.
The Shop
Barnett rode both in 1980.
That 1983 design with the tank swapped with the airbox was abandoned because the riders couldn't get the bikes to handle right like that. It probably made the front end too light.

Works bikes were so bitchin back then. Real one off Formula One stuff.
The #9 is Warren Reids bike. His number was #9 in 1981, so this could have been early 81'.
Here's some pics I saved of a 1980 and a 1981 SR125.
