The TRK52B Trekker is capable of holding an impressive 52 litres, which is 6 litres more than the other boxes in the Trekker range. It is worth noting that unlike other boxes in the range, the TRK52N can only be used as a top box.
A good box - I shall be keeping it - don't want the hassle of returns etc but it is an aluminium 'look' box not aluminium as listed.
Up to usual Givi standard. Has to have a particular mounting plate - another £30+.
Plastic ones can be found a bit cheaper on the Bay.
Good practical size, well constructed, better than Yamaha's original label cases and a lot cheaper. Looks good on my Yamaha XT1200Z Super Tenere. Brilliant value and highly recommended.
