Circa 1972 Penton 125 Trials machine

The growing sport of observed trials now has a new mount to contend with, the new light-weight Penton 125 Trials machine. This new machine is manufactured in England where the sport of trials is the most advanced in the world and the new Penton Trials reflects this advancement. Based on the fantastic 125 Sachs engines as used in the Penton Six-Day, this engine has proven itself beyond a doubt to be the finest small bore engine in production today. The advanced frame design is of Reynolds "531" tubing. Look over the specs and check this new machine out at your Penton dealer if you're an observed trials buff.

1975 Honda TL-250 & TL-125 - ride a sure thing

Of all types of motorcycle competition, perhaps none calls for more special skills than observed trials riding. Speed is of little concern to a trials rider, because his challenge is to creep through an obstacle course that would be difficult even on foot. And to be a winner, he's got to stay aboard his motorcycle - all the while traversing rocks and boulders, easing across narrow logs, and covering stretches of terrain often more vertical than flat. And to earn maximum points, his feet must never touch the ground. Sammy Miller (inset) is that kind of rider. And Sammy rides a Honda TL250 trials bike. The new TL-250 is a big brother to the highly acclaimed TL125 trials bike. So what makes Sammy run on a TL-250? He simply thinks it's the best trials bike in the world - after all, he and Honda engineers designed it together...

1974 Yamaha TY250 - Introducing the first slow Yamaha

Mick Andrews likes the new TY250 Trials. He should. We built it to his personal specifications.

...The engine, like all the other components on the TY250, was built specifically for trials. Its large flywheel design, combined with Yamaha's Torque Induction intake system, gives it the low speed pulling characteristics of a bulldozer.... The TY80 MiniTrials has the same high ground clearance, low center of gravity configuration as its bigger brother...

ISDT: Uphill All The Way

It's really a shame that so little is known about the International Six Days Trial / ISDT here in the United States because it's by far the most complicated and sophisticated game in town for motorcyclists......this was the 3rd year the event has been held in the tiny mountain ski resort town of Spindleruv Myln, Czechoslavakia.....
