I looked for TT's bash plate, which I like on a DRZ, and I do not see one in the parts store for the WR450F model.
I do not want a carbon fiber. I bash mine pretty hard on occasion, and I'll wreck a carbon fiber plate quickly.
Aluminum I can take a sledge hammer to, and straighten by beating on it, which is just compense for me beating up my cycle.
So, an aluminum plate would be best, with good coverage of the oil and water pumps (which I've wrecked by bashing through plates before).
Any recommendations, please?
