I have an 05 WR450 that has been a tremendous bike. No problems in a variety of terrain/riding conditions from hot desert to single track up in the pines. Have done no night riding other than making it back to camp out in the desert on some well groomed flat trails. Headlight worked fine for that. Planning on some single track night-riding in the mountains/pine covered forests in the mountains outside of Southern California. A friend says the headlight wattage on most bikes is not sufficient for that terrain but turns out he has a Honda 400 with only 35 watt bulb. The WR450 has a 55watt lamp. Any experience/tips/advice or recommendations about this type riding and or wattage would be appreciated. Thanks.
