35-year-old Yamaha RD500 discovered (still in its original box)
Yamaha's RD500 was the superbike of its day when it was released in 1985. The two-stroke 500cc V4 engine was similar to that used in the 500 Grand Prix machine of the era ridden by Eddie Lawson.
Today, a good quality example will reach £20,000 - making this box fresh example discovered in Australia worth even more. How could someone forget about this bike sat in its original box, untouched since the mid 80s?
