I live in northern Indiana. We have a short riding season but I still manage to rack up 8,000 miles a year on my Harley Ultra Limited. My bike is my pride and I keep it clean. Still, I was very impressed with this product after torturing it. We drove 600 km. It was 3 a.m. on the back roads of Indiana. The bike was full of insects. So I thought this would be the perfect test. I didn't pressure wash or rinse the bike first (although you should). I pull off a dry bike. Waited 5 minutes and then rinsed with a pressure washer. EVERYTHING went under. I blew it out with an air compressor and wiped it down with tec582 parts spray. It looked like I hand washed it. The wheels are amazing too. No need to clean the nooks and crannies of the engine or wheels. To be honest, I don't think I would have gotten the same results if I'd just used garden hose pressure. There was also no accumulated dirt or dried rain spatter. Just your typical dirt bike after a long ride and mistakes.
