Half-Daft is a SUPPLIER to us, of various items, mostly Honda 650L and 650R, but he does other products as well, so thanks for posting, Half-Daft!
1. the brackets he has manufactured seem to be for TRAX (SW Motech), rather than for Motorradical, which was my original posting.
2. We are aware that in the past, certain ALUMINIUM top-box carriers for TRAX brand cracked...
3 TRAX then re-worked their alu top box plates to be designed tougher, and have had way fewer issues with them.
4. Motorradical top box plates are A-L-L stainless steel, not aluminium. They are practically over-built, and are tough.
5. 2 or 3 models of Motorradical top box plates are SUPPLIED WITH SUPPORTING brackets, the BMW 1200 GS comes to mind, BOTH the newer liquid-cooled and the older air-cooled, so does the new Africa Twin, and the Yamaha Super-Ten as well...
6. We do not recommend ANY top box for offroad travel for ONE particular bike: the Yamaha Super-Ten: we have seen OEM box break the mounting bolts, Globescout, Trax, Motorradical, and others - simply put, there are MANY threads about this bike and top boxes (for OFFROAD use), it simply is often not worth the risk.
7, We have sold well over a hundred Motorradical top boxes, with VERY few comebacks on the adaptor plates, the only one we know of are the odd 'guillotined' bolt on the supporting bracket on 1200 Air-cooled, and then Motorrdical withdrew the Honda NC700X bracket..., a difficult bike for top boxes WHEN USED OFFROAD, etc.
8. Mototradical now makes TWO Honda Africa Twin top box mounting plates for the SAME top box: 1 is when using top box WITH Motorradical pannier racks, and has extra supporting brackets, and then they make a 'stand'alone' top box plate with its own additional supporting brackets.
Hope that clears things up, and thanks for posting half-daft: we are a fan, and stockist, of your products!
