A test of the top motocross and off-road bikes has been conducted, with various models from 2017 being evaluated. Some outlets are focusing on specific bikes, such as the 2017 Yamaha YZ250FX and YZ450FX, while others are comparing different models or providing buyer's guides. However, there is also a mention of a separate test for street motorcycles, which may not be directly related to the motocross and off-road bike test.
