Hot wheels: The world's most expensive motorbike by Bucherer and Harley-Davidson

If you thought motorbikes were for the tough, think again. Fine watch and jewellery maker Bucherer has collaborated with Bünderbike to produce an entirely handcrafted bike — the Harley-Davidson Blue Edition. Handlegrips are topped with Bucherer’s Dizzler rotating ring and a further pair of diamond rings are on the forks. Studded with 360 diamonds, the bike also features a glass dome, under which — in a retractable safe — lies a 5.40-carat solitaire diamond ring and a custom-made Carl F Bucherer watch. To achieve the startling, iridescent blue of the body, the bike was entirely silver-plated before six layers of coating were applied. Finished with gold-plated parts and a cowhide saddle, the bike took more than 2,500 hours to complete and costs CHF 1.89 million.
