Our hearts always leap when a new XTR Pepo comes our way. This time, it’s a 1973 Bultaco Lobito 125 MK7 flat tracker. The Lobito (“Little Wolf”) was an enduro built from 1966-1976, most popularly in the 74cc form, though we have here the 125cc version. The 74cc Lobito was originally designed for a speciific demographic — 16 riders with only their A1 card — but the bike’s aggressive styling and mixed-use urban agility made it a lasting icon of the 1970s — even, some say, a “sociological phenomenon.”
The MK7 you see here had an 11.2-hp two-stroke motor, weighed 88kg, and had a yellow tank with blue stripes — iconic of the Lobito.
Pepo Rosell of XTR Pepo turned this Lobito 125 — nicknamed “Astro” — into a 2-stroke tracker, complete with a Yamaha SR250 swingarm, Honda Hornet 600 front forks, Derbi supermoto wheels, and a load of one-off XTR components. As for name, Pepo says:
“Astro was the name of a bike that Bultaco made specifically for racing in the USA Dirt track championship. It was name Astro because one of the tracks where they raced was in the Astrodome of Houston.”
