My GTR came with an OEM 39l top box fitted which was handy . Big enough to take my rucksack with laptop in etc but could only take one helmet (ok I know you can fit a helmet in each pannier but.....)
On my Bird I had a Givi Maxia which comfortably took two helmets so the next decision was whether to get one of those and also replace the mounting plate (the Maxia is Monokey, the OEM is Monolock) . After humming and haing I settled on the
Blade B47N Tech plus the
optional cover. The latter was ordered in silver which is close but not quote so a friend sprayed it up for me to match.
Piccys speak for themselves. Still to do fit some 10mm red LEDs to the Blade to use as supplementary brake lights (could have taken the easy option and ordered the kit but had some LEDs lying around from a previous project)
