I tried riding with the 9.5" and too short for me. I didn't have one in my brief ride, but I could see a real potential for unintentional engine kills in more difficult sections. I'll stick with the regular elastic ones for now. A Jitsie replacement is only $7 from the Tryals Shop. If I wear out 1 or 2 in a year, that's still cheap. I ride with a complete spare in my water pack, keep another complete spare in the van, and a spare strap too. If anyone is interested in trying a 9.5" cord one, PM me your address and I'll send you one. FIM rule for lanyard kill switch, with maximum lanyard length..... 37.02 Ignition cut-out switches It is compulsory that all motorcycles be equipped with an operational cut-off switch, connected through a lanyard to the rider (max. length - 1m). Once the rider steps off the motorcycle, the lanyard must disconnect from the cut-off switch and cut the power to the engine. .
