VStream® Sport/Tour Windscreen for BMW® F850GS/Adventure

Item Number: Z2378


Availability: In Stock


VStream® revolutionizes windscreen performance! The advanced "V" shape and dimensional contours push the wind vortex out and away from the rider's helmet, resulting in a peaceful, quiet environment. This improvement is notable for the passenger as well.

The Z2378 is a generously-sized sport-touring screen, and will give most F850GS/Adventure riders excellent wind protection while maintaining the bike's adventourous appearance.

State-of-the-art 4.5mm Quantum® hardcoated polycarbonate gives this VStream windscreen outstanding clarity and strength characteristics unmatched by any windshield maker worldwide.

This exclusive combination of Quantum and polycarbonate is 30X more scratch-resistant than acrylic materials, has better UV life, chemical resistance, and optical definition, and has superior crack and impact resistance.

Covered by ZTechnik's 3-Year Warranty against breakage!

NOTE: Z5304 Mirror Extenders required for proper clearances.

Good screen! Review by GS Guy
Install was super easy!

I removed the old shield, threaded in the bolts with the stand-offs loosely to facilitate fitting the screen on. Once the rubber grommets are fitted to screen, push the screen onto the stand-offs, loosen each screw and re-install with grommets included, one at a time. Whole process takes 15 minutes at the most.

I've logged 120 miles with the new screen, despite being a tall person it still provides just enough wind deflection without being so tall as to flex and stress the flimsy ABS plastic GS mounting system. The screen is just dark enough to filter some light without being too dark.
I recommend this one but don't go taller than that! (Posted on 4/12/2020)
