I've been reading everywhere that the CRF450RL is far too exhausting for riding 300 to 400 km (200-250 miles) a day on asphalt or dirt roads. If I replace the seat with a Seat Concepts seat, is it true that this bike quickly wears the rider out and that it would be better to choose a DRZ4S or a CRF300L instead?
