pgeldz Posted July 10, 2020 Share Posted July 10, 2020 (edited) Hey everyone! I've been researching crash bars, and was was wondering how/why companies do the mounting, specifically from an engineering point of view. Wanted to get everyone's perspective on the different crash bars I'm considering, specifically the MOUNTING POINTS of said bars, and how it affects load and impact during use (crash). I've narrowed it down to 4 companies, for various reasons, and highlighted the mounting points of each with Red circles. GIVI - I like that it's almost like the Yamaha design, but more minimalistic, and doesn't interrupt the Tenere 700 logo on the fairing, but still protects the radiator. Mounting: It only has 2 mounting points. One on the upper bar, and one ON the bar. The one ON the bar has a crossbar going behind the headers to the other side to triangulate. Concern: Is it enough? Since it's not braced further back, will those two vertical bars bend? If they do bend, it looks like they are not a part of the frame, and easily replaceable. Also looks like the motor us untouched because it's not braced to it. YAMAHA- Like the GIVI, but goes further up the fairing. Hate how it intersects the Tenere 700 logo. Mounting: Similar to the GIVI, but it adds another mounting point on the two tabs sticking up out of the engine case. Concern: Will those two tabs on the engine case break off or crack on a hard hit? If so, you'd need a new engine case? SW Motec- I like this one a lot. The lines don't mess with the Tenere 700 logo, it comes up enough to protect the radiator, and at the top, it bends slightly further away from the fairing so if the bike is on its side it's further away from surface rocks, etc. Mounting: Like Yamaha, but instead of having the rear mounting point on the two tabs sticking out of the motor casing, it mounts to a lug sticking out of the head of the motor. Concern: The lug sticking out of the head of the motor is connected to a triangular brace bolted to the frame. Is seems like it would be strong, but would a hard hit damage the head of the motor? Adventure Spec- I like the looks of this one a lot. Great coverage, follows the lines perfectly, doesn't obstruct the logo, and it's lightweight, but strong aluminum. Mounting: Has one mounting point like all the others on the upper tube at the bottom of the fairing, but only one more on a bracket near the headstock. Concern: The upper mounting point seems like it could get easily tweaked since there would be a lot of leverage in the head stock area, especially since it's on a bracket. However, since the bars are made out of aluminum and not steel, maybe they would bend or crack before any headstock damage could be done? Also, the headstock area in general make mounting a fender or light bar possibly more difficult. Ok, those are my OCD thoughts on the matter. What are your thoughts on all of this? - Paul Edited July 10, 2020 by pgeldz 5 1 Link to comment Share on other sites More sharing options...
