Les Ateliers Ruby Belvedere helmet, £607
Miles covered/time: 1000/six months
What's good: The Les Ateliers Ruby Belvedere helmet is without doubt, the most luxurious piece of motorcycling equipment ever made.
It's the helmet equivalent of an Aston Martin DB5. Hand crafted, hand painted and upholstered with the softest red leather, the quality and detail of the finish is without equal.
Touches like the small leather panel revealing the carbon-fibre weave of the inner shell only add to the helmets cache.
But perhaps surprisingly, the Belvedere's function is as impressive as its form.
The four-position visor design (two tinted visors are included) is especially remarkable with the spoiler directing all but a whisper of air away from the face.
It's also the quietest helmet I've ever worn (full face or open) plus it conforms to the UK legal ECE22.05 standard.
Other motorcyclists' reaction to the Belvedere is distinctly Marmite with the majority hating the helmet's quirky style and outrageous cost. But this isn't a cynical exercise in charging a high price for something that doesn't deserve it.
Unlike a typical mass produced helmet, the time, effort and craftsmanship is clearly visible.
After six months of summer use the Belvedere has become my all-time favourite piece of motorcycle kit.
What's not: Nothing. Yes, it is worth £600
