In case anyone is interested, OSSA's warranty support is FANTASTIC. My Explorer's plastic fuel tank (the additional plastic auxiliary unit in the conventional position) had two thin spots that were clearly rotomoulding defects. Within ten days of sending my email (with photos) explaining the problem, I had a new tank delivered to my door by the UPS man... directly from Girona. That is what I call first-rate service. It does not get any better than that.
