I fit a B&B Engineering sump guard to my WR250R, looking at the overall product, fitment and my thoughts after the first adventure ride.
This is a heavy duty aluminium guard that clips onto the frame on frame bolts and uses two front mounting bolts, for a simple and easy install, that should be very secure.
The build quality is great and while there’s some additional engine noise reflected back at you, it suits the look of the bike and is well integrated.
