I have used them on a scooter and a naked bike, although I shouldn't, as they are intended for motocross - off-road use. I bought them to try them out because of the rave reviews about their feel. For road use, they offer no protection, apart from the fabric "pad" on the palm and have no certification for protection. The material does not seem very resistant to friction. Indeed, they have a great fit, but it is not much different from all the summer fabric motorcycle gloves with protections. They have the best ventilation in the summer to the point where you can't use them in other seasons. It's like not wearing gloves at all. The fox sizing chart is accurate. The velcro does not seem like it will withstand the test of time and may fray / not fasten. A fair purchase for someone who wants perfect ventilation, fit, and does not want gloves with protections. However, for their price, there are many very good summer gloves with protections and good ventilation.
