This luggage rack has been designed and manufactured exclusively in India by Z Pro and tested over one year of usage with bags and small top cases (plastic only) by mainstream European manufacturers. This rack is not compatible with aluminium boxes or Chinese boxes. The rack enables the rider to mount a bag across the axis of the motorcycle to maintain the centre of gravity and balance on the Triumph Street Twin. The pillion seat, being very small, does not enable carrying off big luggage bags. This is where this rack comes in handy. The top rack plate on the part is made entirely of lightweight yet durable aluminium. The entire assembly is mounted on very thick and heavy-duty (using all stainless steel hardware). Like all Z-Pro products, this rack comes with a full, lifelong warranty against any rusting whatsoever..
