I recently decided to get myself a decent top box for the bike. I have been using some Oxford cloth panniers, which have been fine but proved less than ideal for carrying my heavy chain and lock. Often sagging down on one side, unbalancing the bike slightly and precariously pressing down on the rear indicator stalk.
When it comes to top boxes and hard luggage in general, Givi is the brand to have. Givi has two levels of products the basic Monolock range and the better Monokey range. The latter is higher spec’d to carry more weight, for higher speeds and more weatherproof. To fit a top box, I first have to fit some a rack to the bike, which consists of some motorcycle model specific arms and a universal mounting plate. For the Fazer FZS600 this is the Givi 340F rack and the M3 plate (for Monokey boxes). This pair normally sets you back about £95-100 in the UK, however, I was able to find a shop on eBay that could post the pair (brand new) from Italy for about £60 – bargain. You may be able to source one secondhand, but finding one in good nick with all the bolts and fastenings is not easy. And note, slightly different bolts are required for the early ’98-99 Fazer to the later ’00-03 FZS600.
