2026-10-07 11:50:00 2026-10-07 12:00:00 America/Los_Angeles No Reserve – 1976 Bultaco Frontera 370 Panorama City, California - A Pursang at heart but built for the trail, the Frontera 370 paired Bultaco’s competition bred 370cc two-stroke with a wide ratio gearbox and enduro ready equipment. https://iconicmotorbikeauctions.com/auction/no-reserve-1976-bultaco-frontera-370/ Iconic Motorbike Auctions concierge@iconicmotorbikes.com

When Bultaco wanted to introduce the Frontera to American customers, they said it was “bred from the Pursang and the demands of the American Enduro experts.” The idea was that you’d get the off-road capabilities of the MX Pursang, but with a wide-ratio transmission and lighting for dual-sport usage. Or as the Spanish firm put it, “The Bultaco Frontera, the hi-speed Enduro bike you have been waiting for!”

The Frontera was a bike that you could explore with in an easy to live with way: in a 1977 review, Cycle magazine said “Frontera power is the gutsy, low down, dig in, tractable kind of torque that will take either [250 or 370] bike anywhere and makes them ridiculously easy to ride.” This was also a fair description for the slightly older 360, also known as the Model 143.

The 370 was distinguished from the 250 by its red and white finish and was developed squarely for motocross competition. Period testing praised the new Pursang’s combination of tractable power, suspension performance, and responsive handling, with the contemporary Cycle World review noting that Bultaco had once again produced a competitive motocross machine.

This example is VIN: HB-18100263.

The odometer shows 987 miles.
