A 1984 BMW R80 ST given the custom treatment by Spanish bike building experts Fuel (www.fuelmotorcycles.eu)

Fuel calls it the R80 STrial. It’s based on a 1984 R80 ST and was inspired by the Triumphs, BSAs and Pentons of the 1960s.

The philosophy is light bikes, with small headlights, flat handlebars, minimal seat and off-road tyres.

The STrial was commissioned by a classic bike enthusiast living in the Austrian Alps and took five months to build.

The front forks are from a BMW K75 Sport, with a 320mm oversize front disc and four-piston calipers.

At the rear the STrial uses Wilbers shocks with multiple adjustments, whilst the rear subframe has been made slimmer and lighter to complete the look.

The headlight is from a classic Spanish trials bike, whilst the tank is Kawasaki, incorporating a gearshift on the side from an old Ural.

There’s a Motogadget speedometer, handlebars are by Tomaselli, indicators switches are from an old Triumph, classic enduro grips and a car type starter motor relocated to the side of the bike.

Fuel is a small team out of Barcelona. Worth visiting their website to see what else they do.
