Very well suited for stock chassis with Twin shock absorbers. E.g. HONDA-Bol d`Or, KAWASAKI Z/GPZ or SUZUKI GS/GSX. And of course for special suspension systems such as RAU, GODIER GENOUD, MARTIN, BAKKER, EGLI with Twin shock absorbers. We, the BIKE SIDE team, have installed this sport ourselves on our ENDURANCE-Racer and put it through its paces. Our conclusion: A TOP PART! The sport is made of GRP and comes unpainted with a TÜV material certificate. total length: 760mm, width ( widest point on shock absorber attachment): 350mm, height: 290mm. Weight: 1400 gr.
