Cl '" ~ . '" .... '" Cl u The 123 pulled this little cliff climb in second gear. It was not a straight shot from the bottom and the dirt was loose. Any serious doubts about the pulling power were quickly dispelled when I came around a tough comer out of shape, but still went up a four foot plus rock face with a step immediately follow.ing. What makes this impressive is that the 125's of the past had to be kept buzzing. Once you rolled the throttle off in a spot like that it was allover. 1 just did it twice in the same section without planning to. You could tell it was loaded but it didn't stop pulling and 1 weigh 165 or thereabouts. Sharp turns and off-cambers are easier than on the 250s I have ridden. The front end is so light and predictable the floating turn is a breeze. Run the front wheel up a bank turn full lock and hold a steady . throttle. Apply the desired amount of body english to turn and roll off the throttle where you want the front end to come down. Or, with a similar procedure you could skip the front wheel from rock to rock. Off-cambers also require a great deal of finesse. T-Iere the Iigh tweight and smooth. tractable power is a real asset. The ligh tweigh t allows the rider to mancuver the bike with less effort. The trick here is when the wheel starts to slide, lean the bike away from the hill. alice, I said the bike, now necessarily the bod y. Th is gives the tire face a better shot at the ground. The specially designed tires, 2.50x20 front and 3.75x17 rear, are by Pirelli. They contribute greatly to the handling and tractability. Ground clearance of 11.6" is not hampered because everything is proportional. Thc smooth power allows a rider to main lain, or even gain speed on almost any off camber. To complete our test we decided to ridc a loop of what is considered to be the toughest Trials event in the United States. The San Diego Scottish One Day. This loop this year w,as 20+miles and 22 sections three times for Master and Expert riders. that's 60 miles with 66 observed sections and a time lintit close enough to kcep you moving. Both man and machine had better have their garbage together just to fmish. Off we went in 100 degree heat to see what the bike could ·do. After a quick clean ride on No. 1 we hit the first of the tough trails: riding in a wash 1·1/2 times as wide as your bars with rocks, sand, and 20" walls straight up on both sides. It took 10, guys an hour to make a way out of the wash so we could use it in th e even t. umber 2 was Master·Expert only section and a two dab score was recorded because the rider took the wrong line and almost blew. it comple tely. The next part of the trail shot down quite a few riders. A long, loose, rocky .-~. . .. .... ~~ ~---- up·hill had riders on the seat and both feet on the ground. The 123 went up the hill in third gear, feet on the pegs. The engine did ping on me once or twice when I rolled the throttle off and back on quickly to jump over rocks or take advantage of traction. This was attnbu ted later to the high temperature and a not-so-premium batch of gasoline. The plug color looked good so we rode on. We hit the longest stretch of road on the loop: 3 miles; and were running 30 to 40 MPH. The rated 50 MPH top speed is about right as the motor was starting to wind up at 40. The only time we bottomed the suspension all day was when 1 had lard in the seat and hit a dip at 35 or so. 1 should have been on the pegs. 1 jumped off rocks, ledges; down rock staircases and' back up again. The suspension perfonned flaw lessly. The en tire loop and sections were ridden without any problems. The original stiffness in ! .L . -.- .... . Good control on a dropoff (The same cliff climbed in the opposite photo.) was helped with a perfect front brake and rod--actuated rear brake. begun to work its way out with the six speeds evenly spaced. Without any big jumps in the gearbox, the righ t cog was only a tap on the lever away. The 64 dollar question is: Can you beat the 250s on a 123? In the Novice and Amateur classes, for sure. We have a bunch of real fine young riders who just are not ready for a 250 size bike. There are some young ride...s who handle a 250 pretty well. But when they get in trouble in a tough section forty pounds is lot of difference to a 107 or 140 pound rider. If the whole event is tough, I have seen that 40 Ibs. flat wear out a good rider. The machine has the ability if the rider has the talent to be No.1 in the Novice or Amateur class. Even some riders who have not done well in the past may "tum on" with this m·achine. How about the Master and Expert classes? At this point you could even go into rider personality. 1 will try to sort it out a little. Masters and Experts are now riding and cleaning sections which, Jumping off rocks and ledges did not bottom the suspension. ~ ~.~. ~ .. a short time ago (2 years) were thought impossible. Riders' and motorcycles have improved. With this improvement, inclividual sty les have cropped up, Certain basic techniques are similar but the rider picks up his own line and uses his ability. The individual's ability to use his equipment to the best of its ability is t\1e difference between first and last place. Certain sections could be made to favor either machine: 123 or 250. The fact that international class riders can .negotiate terrain -on a 123 that we cannot on a 250 lea'les little doub1: the machine is capable. The rider would have to be more aggressive in some sectiond due to the engine size bu t could take advantage of outmaneuvering the bigger bike. All of this is considering you are a serious competitor. Whether you are or not, it's O.K. with the bike. It is fun to ride, and I haven't had that much fun in ye;ars. '.
