The hibernation is over.

Unlike grizzlies, BMW Airhead motorcycles hibernate in the summer, when it’s too darned hot to leave a vintage machine in a 130F greenhouse passing as a garage, here in Scottsdale, Arizona.

Back on May 1, 2020.

So with temperatures finally dipping back into single figures, it was time to get the 1975 BMW R90/6 out of its refrigerated comfort zone and back on the road. Where it belongs.

The Odyssey gel cell battery needed no recharging, having dropped from 13.11 volts to 12.97 volts. On the other hand, the tubed tires did need air, each having lost some 50% of the usual 32/36 pounds in pressure. Easy. Oil? No need to check. German motorcycles do not leak.

So a gallon of high test later – the tank had been drained before indoor storage – a prod or two on the kick starter to get oil to the piston rings, full choke just for the start, a touch on the electric starter button to get that huge, antique Bosch lump of a starter to do its bit, and off we go. Kicking those big twin 450cc pistons into life from cold is no fun. Electric starting is the way to go, introduced in Airheads in 1970.

Nothing, but nothing, beats two motorized wheels.
