ok i know these are made of ally, and are not meant for the weight of a pillion. as you might have read i went touring in scotland, i got a pillion seat unit and just bodged it onto the mono subframe just to carry soft panniers. i had about 10-15kgs in the panniers and got a bit of airbourne action in scotland. cleaning the bike today the subframe has completly snapped both sides towards the rear :| and looking at the thickness of the metal it looks like its not meant to carry any weight at all.
anyone know where i can pick up another Mono subframe ?
I remember when Bike magazine first road-tested the 999 monoposto. They snapped the frame too, without the luggage. If I needed any further persuasion to get a Bip, there it was!
I think it was colin chapman who spoke about car parts saying if they didnt last a race, they were too weak, and if they lasted longer they were too heavy/strong.
its a mono seat frame, designed as such.........extra weight over the rear of the frame (inc the leverage effect from the mounting points) it wasnt designed for!
