Took me a little time find and take pics of the XR4, but here are a couple. I have had this XR400 since '96 and love it. I raced it in amatuer enduros & local hair scrambles a little back then. Now I commute on it whenever I can, ride with my kids on their PW60 & XR70, & wife on her CRF230.
No performance mods to speak of.
Utility mods include:
Baja Designs kit and plate in '96,
16T front sprocket
Duro dual sport tires (cheap commuting traction)
Passenger pegs adapted off a CBR I think
Top box from JC Whitney (for daily commute, not tested off-road)
Rear rack from Ebay (cut to fit around DOT taillight)
Clark 3.8 gallon tank for longer trips
Blue artwork from Ebay (not recommended, stickers are not sticky
