This might be Costa Rica's only "Rat Bike" according to owner Nestor, whom I had a brief chat with at the Los De Xibalba Swap Meet on April 29th, 2012. Might not be the "only one" but it certainly has class!
I tried to find a link to the Spitfire M/C of Costa Rica, but couldn't locate one. Translating Spanish is not my strong point. If anyone reading this from the Spitfire M/C has a link, post it in the comment section below and I'll be glad to link you up. Si a cualquiera que esté leyendo esto desde el Spitfire M/C tiene un vínculo, puesto que en la sección de comentarios a continuación y tendré el gusto de enlace.
