The four Alpinas all use the same frame, which is practically a carbon-copy of the Sherpa T frame. Riding the 350 Alpina is more like riding an old 500cc four-stroke Single than a medium displacement two-stroke. The 350, on the other hand, puts out its maximum of 21 bhp at 5000 rpm and a whopping 21.5 lb.-ft. The 125 is the buzziest engine in the group, developing its maximum power at 8000 rpm. >ДЄll-out performance is not a criterion for these machines so their port timing is on the mild side with good power available from ultra-low rpm right up the scale to peak power speed.

The first three gears are more widely spaced than on a Sherpa T as are the top two speeds, so keeping the engines in their powerbands is easy. A single row primary chain transmits the crankshaftвЂ™s power to a clutch with all steel plates which will take an extrodinary amount of abuse before it gets hot enough to slip or drag.ДЄll four Alpinas have the same internal gearbox ratios which are ideally suited for the machinesвЂ™ intended usage. On the Alpinas a Femsa flywheel magneto with lighting coils is installed on the left hand end of the crankshaft while additional flywheels are mounted on the right hand (primary drive) end of the shafts.

In typical Bultaco fashion, the engines feature vertically split crankcase assemblies. In order to get a good sampling of the four Alpinas, we requested a 175 and a 350 for test, and although the handling qualities are practically the same, the 350 has much more tractive power than the 175. The same crankcase assemblies, except for flywheel weights, are used and the big differences to the engines are different size cylinders and pistons. But the first Alpina, introduced near the end of the 1971 season, was available with only a 250 engine, which was okay if your bag is to ride the 250 class in enduros.ДЇor 1973, Alpinas are available in four of the most popular engine sizes for enduro competition: 125, 175, 250 and 350cc and almost all the cycle parts are the same.

lighter than the more fully equipped Matador and is the ideal set up for short enduros and pleasure riding. In its present form, the Alpina is almost 50 lb. Alpinas really feel strange for the first few miles, unless of course you have been preconditioned to the trials attributes of high pegs and low seat ala Sherpa T.ДЄctually in its first guise the Alpina held many of the virtues of the Sherpa T: good bottom end power, a narrow profile and a redesigned seat/gas tank combination with greater fuel capacity and a softer padded seat. Why? Because this ultra lightweight will not slide due to a considerable rear weight bias. However, riding one requires a definite readjustment of riding style.

Although the Matador was a machine that could be used for these events, many riders wanted something lighter and more maneuverable for use in these short events as well as a mount for strict pleasure riding. It soon became evident to Bultaco representatives in America that there was a demand for a Sherpa T which would be more suitable for the popular one-day enduro contests in this country.

The Bultaco Matador, on the other hand, was developed by the factory for competition in the famed International Six Days Trial and is a more ruggedly built and heavier machine than the Sherpa T, with long distance enduros being its strong point. Call It вЂњThe Great American One-Day Machine.'Д«ULTACOвЂ™S Sherpa T, the world reknowned observed trials machine developed by many times world champion Sammy Miller, has won over a large following in the United States and in other countries as well. The Lightweight Alpina Concept Is Something New And Unique - Borrowing From Both Enduro And Trials.
